Feature Request : IPv6 Fasttrack

Tue May 25, 2021 2:08 pm

Hello there.

Creating this dedicated topic after reading the post of raimondsp :

viewtopic.php?f=1&t=175369#p859010

...

. We cannot do Fasttrack offloading until the software IPv6 Fasttrack gets implemented. The latter is on the TODO list (backlog) but not on the roadmap yet. I suggest creating a feature request thread on RouterOS v7 forums for IPv6 Fasttrack - if it gets enough user attention, it might receive a priority boost.

To me, with ipv6 being more and more needed, having to give priority to ipv4 for performance reason is not a good place to be in. And since CCRs without switchchip won't be able to use h3 l3 offloading, I would like to see ipv6 fasttrack in RouterOS v7.

Thx.

I have no problem with IPv6 performance (Fasttrack is always the first thing I disable) but I think IPv6 deserves way more attention from MikroTik, the "our customers never ask for it" no longer cuts it.
When that includes Fasttrack development for some people, I welcome it to be included (as long as it can be disabled).

IPv6 adoption has already reached 40-50% in many countries as per Google statistics. It shouldn't be treated as second class citizen in RouterOS. People expect IPv6 to provide the same performance as IPv4, which is only possible with Fasttrack.

The amount of IPv6 work we have done as MikroTik consultants in the last year has been staggering. We rarely build a new network without designing for IPv6.

This is a critical feature, please give it priority.

I advise you to buy routers that can run your workload without fasttrack.
IMHO fasttrack is more targeted towards home routers where the user wants to get the high bitrate of their modern fiber or cable connection on an outdated router model.
In a WISP, when you would want to do any connection tracking at all, you should not need that extra performance tweak but rather get faster routers.

IPv6 Fasttrack is a must in 2021, as most of the MikroTik devices are not capable of gigabit routing when IPv6 is involved.
my hAP AC^2 is only capable of ~600mbit on IPv6. my RB4011 uses 22% of CPU when passing ~1gbit traffic

No fast-path on the edge, Yes fast-path on all your distribution routers where you don't need to inspect most packets. An est/rel IPv6 fast-path for distribution routers is a real must have these days now that many of us are pushing >3Gbps between pops.

+1. Just bought my first MikroTik router to use on my 1Gbit connection and was very disappointed to see that I can only get that speed on IPv4. IPv6 runs at less than half the speed unless I completely remove all firewall rules. That is pretty unacceptable for 2021 when 50% of traffic is now using IPv6.

would love to see ipv6 supported in fasttrack, ipv6 is fully deployed in my network and the only hardware that can currently handle anywhere near 10gbit/sec is the CCR2004. fasttrack support for ipv6 would introduce many new options for l3 routing in my network.

At home I have DS-Lite from operator. With GPON Huawei router I have 1G connection speed, but when I made the same scheme of connection via Mikrotik hAP^2 more then 220Mbp/s I can't see.
Without IPv6 fasttrack next development of system are not possible.

This is 2021 final quarter. Please implement a proper IPv6 stack. It is till way behind other vendors. Recursive routing is still not implemented. Time for mikrotik to pull up the socks. Docker and stuff can still wait, core functionalities of a router must be the priority.

Totally agree. There seem to us there is no clear vision what Mikrotik wants to be. It wants to be Home/SMB/App-developer/5G/IOT and at the side it also route ipv6 packets for enterprises.

To be a home router supplier you need to support IPv6 as well! Maybe the current state of things (except maybe "Fasttrack") is good enough for that, but still there are many features to be brought on-par with IPv4 that are also useful in home use.

I totally agree: IPv6 is a matter of present for everybody and should be trated and supported as such. No amount of turning blind eye will change that.

While advanced features such as NATv6 would be nice to have, it's basic IPv6 support that has to be brought to higher level and it has to be done like yesterday.

Why are you talking about benchmark ? We should just accept that ipv6 is way slower than fastracker ipv4, at a time where ipv6 is more and more used ?

Re: Feature Request : IPv6 Fasttrack

It is explained in the 7.1 release topic.
Before, there was a "route cache" in the Linux kernel which meant that it would keep the last routed address and when a next packet is to the same address, there is no need for a new route table lookup (actually there are a few addresses in this cache).
So in v6, when running a speedtest, this cache was used and it was faster.
However, in the current Linux kernels (not something decided by MikroTik!) this cache no longer exists. So each route has to be looked up in the table.
This means that a speedtest runs slower.
However, in real operation, there is communication with a lot of different addresses, and this cache was not every effective anyway.
So the "normal use" will not be much slower, certainly not as much as "indicated" by the speed test.

Fasttrack is another level of such caching, where even more of the connection state is used to bypass checks done on each packet, e.g. the firewall.
Sure it would help, but you should always understand: when you need Fasttrack to make your internet connection perform at its rated speed, you have bought a router that is too slow for your line.
Fasttrack can always be replaced with a more suitable performance router.
I always disable fasttrack because it is incompatible with some of the features of the router I use, and for me it is too much work and too risky to find out exactly what can be fasttracked and what not. So I just bought a faster router.

I fear that for some Mikrotik hardware something like Fasttrack offload is actually necessary to maximize throughput, no matter how fast the CPUs. The CCR2116 offers 52G of port throughput, but this ports only have a 40G connection to the CPUs, so at least 25% of the traffic would need to be L3 offloaded to the switch chip to reach full L3 port speed with at least some L3 processing rules.

I expect most people complaining here do have an internet connection somewhere in the 300-1000 Mbit/s range and a router that at best can route up to 200 Mbit/s, or even less when there are other performance-limiting factors (PPPoE etc).
With such devices it can help to have Fasttrack. It helps to optimize the common case and it certainly will promote peace of mind by showing good figures on speedtest sites.

When you have a complex setup with VPN tunnels, QoS, policy routing etc it will be easier to just disable Fasttrack and throw some more hardware at the task.
For example, I currently have a 30/180 Mbps VDSL line and I use a RB4011. No issue at all to operate without Fasttrack.
Before, I had a RB2011. That would not be able to do this.

Thanks for these words, this is what people seem to forget: get the right sized hardware as a starting point, many devices are not fully gbit capable and while very welcome fasttrack can only do so much.

In addition to limiting all-ports routing speed, lack of Fastttack might also limit single-stream performance, e.g. viewtopic.php?t=131503. I expect you can't buy a Mikrotik with enough CPU power to achieve certain single-steam performance goals (or multiple high-throughput streams, where the number of streams exceed the number of cores) without hardware assist. Offload is the only answer.

So the "normal use" will not be much slower, certainly not as much as "indicated" by the speed test.
I consider large single stream downloads to be the "normal use" case for home use. And speed tests are perfectly fine at representing the transfer speed achievable for this.

Most people don't pay for hundreds of Mbps download speed at home to watch video streams, a fraction of that bandwidth would be enough for that. The few moments, when you can really benefit from high bandwidth at home is large downloads. When you download a 100 GB game from steam, you don't want to wait for 45 minutes when it could be done in 15 minutes with the same hardware.

Mikrotik enables IPv4 fasttrack by default in their home devices, so they clearly acknowledge its usefulness in this scenario. Trying to tell everyone that they are wrong about wanting fast downloads on cheap devices because it's not what you consider normal use doesn't help.
The existing discrepancy between IPv4 and IPv6 performance should be fixed.

Lack of route cache doesn't explain the noticeable decrease in speed like we see,speedtest or other usages...

And hell, even with V6 some of us want fastpath for ipv6.

Absolutely crucial feature!
We use some CCRs to provide service to some student-dorms at our university. IPv6 lacks behind IPv4 with NAT in terms of speed... That's not a good thing in 2022.

I'm disappointed by the lack of IPv6 fasttrack - just bought an HAP AC3 and it maxes out single core at 500mbit/sec. For anyone running IPv6 with gigabit at home this is a deal breaker. Please implement Fasttrack ASAP!

We cannot do Fasttrack offloading until the software IPv6 Fasttrack gets implemented. The latter is on the TODO list (backlog) but not on the roadmap yet. I suggest creating a feature request thread on RouterOS v7 forums for IPv6 Fasttrack - if it gets enough user attention, it might receive a priority boost.
Add me to the list of people that would like to see it. I have the RB750gr3. Currently my connection is 500mbps, but if it increases in the future, it would be nice if the router would be able to keep up with it.

+1 for IPv6 Fasttrack.

I've been using dualstack since 2015, but last year I upgraded the uplink to 60 GHz (500/150 Mbps) and the router to RB3011, but the fasttrack would still be very useful.

IPv6 adoption approaching 40% globally according to Google[1], and 25-30% according to Cloudflare[2] and Akamai[3].

This is arguably higher priority than anything related to ZeroTier / Wireguard, QoS, etc since it is a fundamental part of most networks now.

They have. It's actually even linked in the very first post.

And yes, some of the SoCs and switch chips Mikrotik uses support IPv6 offloading.

I was wondering why I had slow performance over IPv6 on my newly purchased hEX S and a gigabit connection - turns out the lack of IPv6 Fast Track is the culprit.

Adding my +1 to this feature request, as without it I've essentially downgraded when I switched from eero.

Quite of a few of the switch chips do support IPv6. hAP AC2's AR8327 for instance does. Hopefully we see IPv6 fasttrack make it onto these older units.

I would however settle for new models in similar price points with IPv6 acceleration out of the gate. I'm not that tied to the current models, it's just that getting IPv6 speeds requires dramatically more hardware. Can't sell a customer a 500Mbps internet service with IPv6 enabled on any of the 'CPE' level devices.

The practical differences are just where the packets get identified for hardware accell. ie, does the switch pluck them out and route them (hw accell...) or does the CPU identify what can be run through a hardware path and pass that to the switch (fast-track). In the end, for 99% it's irrelevant.

Then it is clear that you do not get it!
IPv6 fasttrack is not IPv6 routing at switch speeds!
It is an improvement over the current routing by using a method of shortcut around the many features provided by the router.
Thus certain thinks will not longer work, but packets for existing (tracked) connections can be routed faster.
This has NOTHING TO DO with L3 routing by switch chips, that is an entirely different animal, supported only on a couple of new devices, and restricting the functionality much more than fasttrack does. Most "users of internet at home" will not be able to use L3 accel, but they could use fasttrack.

Hi,
I heard rumors of my ISP finally beginning to understand that there is a need for supporting IPv6 for private customers. (yes they are horrible and there is severe lack of competition here, they are providing IPv6 already, but until now with severe restrictions)
So +1 for IPv6 fasttrack as I have lots of customer grade MT routers (HAP AC2, HAP AC3, HEX S, WAPac with LTE) on uplinks with several 100s of Mbps, currently running IPv4, but soon to be converted to primarily IPv6.
Ah and I have those routers in two cities with 2 million inhabitants each, so there are probably a few other MT routers to be found there.

Regards
W

Have you tried adding an IPv6 firewall rule under the "raw" category? This bypasses the connection tracking part of the firewall. Add two rules. First rule should be to match src addresses. Second rule to match dst address. Both rules should have action "no track".

i think there is a problem with that approach because raw rule still catch and process all traffic, so it will not give the boost fast-track provides

for example:
ccr1036 8g 2s+ can forward almost 20gbps of internet traffic in routing mode with conn-tracking enabled and some ip firewall rules thanks to fast-track
ccr1036 8g 2s+ can forward almost 10gbps of internet traffic in routing mode with conn-tracking enabled and some ip firewall rules doing heavy Carrier Grade NAT thanks to fast-track

without fast-track you don't achieve half of that

that's the kind of improvement we are talking about

The only way to maximize ipv6 throughput on these is to have zero forward rules and no connection tracking. Without any sort of fast-path or hw accell it comes down to touching the packets the least and spending as little CPU time evaluating as possible. This is true of fast-path ipv4 as well really. Do some tests across a mipsbe board with fast track vs no forward rules and no connection tracking. it's a pretty dramatic difference. Not as much as no rules vs passing the firewall chain down but pretty dramatic still. fast-path/track is just minimizing CPU processing but it's still CPU.

I'd really love the whole suite, fast-track/path and hwaccel on supportable hardware for sure.

I agree with you.

However, it will give you extra performance until the feature is implemented. Because you are matching traffic based on the src/dst addresses early on, you are skipping a lot of overhead.

how much extra performance you are talking about?

it is still standart track. should be same as no queue and no FW rule

Australia is rolling out 1Gbps capable technology to all houses now (and over the next few years).

One of the properties I manage is getting it this week, but their hAP ac2 is unable to do 1Gbps routing over IPv6.

We need this.

(and before you ask, every major CDN can transfer data at 800Mbps+ here.)

You can always buy a faster router. Or live with the situation that you cannot saturate the 1Gbps line. The user won't notice it in normal usage.

This isn't IPv6 fast track but it is a step in the right direction.
This is very exciting...



Can anyone provide more information on this? What switch chips are supported? Does this mean that IPv6 fast-track is being worked on?


Robert

L3HW IPv6 is now supported by all CRS3xx, CRS5xx, and CCR2x16 devices.
IPv6 FastTrack HW Offloading is not implemented because the software IPv6 FastTrack needs to be implemented first. Unfortunately, I don't have information about the latter.

Maybe the hardware (SoC) has capability to do PPPoE without CPU use?
Do you run a connection-tracking firewall in there? Or is it just transparent?

Standard firewall available in current OpenWrt version, they switched to nftables from iptables.
https://docs.kernel.org/networking/nf_flowtable.html
There were some hiccups until now, problems with PPPoE beeing unable to be HW offloaded, IPv6 unstable, but there was a lot of work in OpenWrt regarding this and it all looks/works better now.
Even this got some attention and fix: https://forum.openwrt.org/t/2-gbps-wan- ... ces/131478
It's sad that only the PPE inside some mt76xx devices is currently supported but it's still something :)
root@OpenWrt:~# grep HW_OFFLOAD /proc/net/nf_conntrack | wc -l
581

That's 581 hardware offloaded flows.
This is how a conntrack entry looks like:
grep HW_OFFLOAD /proc/net/nf_conntrack | grep 2a
ipv6     10 tcp      6 src=2a02:2f0d:xxxx:8806 dst=2a03:b0c0:xxxx:9001 sport=59630 dport=443 packets=8 bytes=1112 src=2a03:b0c0:xxxx:9001 dst=2a02:2f0d:xxxx:8806 sport=443 dport=59630 packets=222 bytes=134837 [HW_OFFLOAD] mark=0 zone=0 use=3

I like RouterOS too, but this RB750Gr3 served well beyond how much I was expecting to use it.
With the bandwidths ISPs are offering here (since a few years now) this device can't keep up while using RouterOS, like I've said above, it was sitting offline gathering dust.
In RouterOS v6 it suffers from the weird port / CPU lane layout bug, in RouterOS v7 performance decreased, IPv6 performance is bad in both versions etc.
I was curious what changed in OpenWrt since I last used it, seems like a lot.
I'll play around with it a little longer and repurpose my RB5009 into a switch + wireguard endpoint + containers, for now. I'm done betatesting it as a router.
Every few ROS7 releases something breaks in DNS or DHCP, it's not like your network depends on those services.
And I don't know if it's just placebo but the network feels snappier somehow, even browsing this forum, which is weird. (altough sniffing with wireshark the forum seems to have IPv6 issues again).

Is the hardware acceleration of IPv6 tracking and PPPoE handling part of the standard Linux kernel, or is that something done internally to the OpenWRT project?
I would think when the standard kernel supports it, it should be available within RouterOS v7 as well.

Most of it finds it's way in the kernel, https://patchwork.kernel.org/project/ne ... @nbd.name/
MikroTik won't use something like this, as it's not an universal solution :) and they only have so few devices that can benefit from this.

just started with using Mikrotik routers and I'm really surprised this is still not implemented. Wondering whether going the Mikrotik way does really make sense.

Only hardware related to MikroTik, RB750Gr3 in particular, since it was gathering dust unpowered for a long time now, I wanted to try some OpenWrt on it today (SNAPSHOT built 29.09.2022) and here it is:
And no, the "top" screen isn't frozen, that's the actual cpu usage .... none.
WAN type is PPPoE, dual stack IPv6-PD
fast.com ipv6 20220930-0001.png
RB750Gr3 OpenWrt snapshot r20784-ec8fb542ec ipv6 hw_offload.png
Interesting... I've checked the MT7621A block diagram; there seems to be a built-in Hw-NAT in the processor itself.

No news? I returned a hAP ac2 a year ago and sold a RB750GR3 because it wouldn't go past 200-250 mbps while using ipv6 (I have a 1 gbps connection), and the rest of the devices suffered from the router not being able to provide for them. Every once in a while I look for news regarding this, but... At this point it's probably not worth to waste a few minutes and be left disappointed every time.

I stayed with the router the ISP provided (which achieves full speed with ipv6) but I think it's time to give up on Mikrotik and look for an alternative (willing to listen to viable options, obviously via private message).

Why would you benchmark using such ancient devices in the first place? My CCR1036 can do 20G+ on IPv6 no problem. For home, buy a hAP ax2/ax3 or RB5009UG+S+IN

That's not the point. The point is the gap between fasttrack ipv4 and non-fasttrack ipv6.

No, that is incorrect! The packets are checked against firewall rules UNTIL ONE MATCHES.
And as the first rule is usally "accept established/related", the vast majority of packets is only checked against one rule.

Maybe some guys should stop waiting and invest on RB5009, or whatever recent device / vendor capable of +1G
I am thinking Mikrotik is moving forward to "detach" true L3HW from (software) fasttrack. That's what happened with IPv6.
Whatever the benefits once provided, fasttrack sounds like a massive kernel hack... which would not be easy to maintain forever for every device/RouterOS release/kernel upgrade

You cannot expect to do 1G++ networking with full features on 10-year old, 50€ devices...

Improving thoughput by SW hacks is very common, it´s always called by different marketing terms, but most big names have something similar like FastTrack.
HW acceleration is not strictly bound to SW accel.
Just look at the open source FD.io, VPP, backed by Cisco:
https://en.wikipedia.org/wiki/Vector_Packet_Processing
Other vendors have other proprietary implementations, like CoreXL, SecureXL,

We want to have power efficency these days, more than ever, so please squeeze out everything from the CPU!
It doesnt matter, how it´s implemented or what is it called.

+1 for this feature.

I bought a MikroTip Hap ac² and now after setting up everything to my wishes I did a lot of speed testing to ensure I get my 1 GBit/s fiber connection like before with a router without proper VLAN support.

IPv4 CPU Load is around 15-30% (mixed on all cores) when running at 1 GBit/s - all fine
IPv6 CPU Load is nearly 25% (100% on one core, other cores idle around at 0-4%) when trying to run the 1 GBit/s - I get around 400MBit/s at 1500 MTU and 140MBit/s at 500 MTU size. This is just bad. I can understand, that buy a router with larger CPU is a way to solve it. But in my case I just expected it to work "exactly" like IPv4 speed wise.

Not loaded the ping timings via IPv6 are better on my ISP, so disabling IPv6 on clients when I want speed is kinda sad and not the setup I hoped for when the routing benchmark states nearly 2 GBit/s of performance with all the basic rules.

At least update your benchmark sites to reflect the speed problems with IPv6 routing. https://mikrotik.com/product/hap_ac2#fndtn-testresults

Re: Feature Request : IPv6 Fasttrack

It would be really nice if Mikrotik would finally start using IPv6 in their offices, their web etc etc.

Now they seem to be very happy with plain vanilla IPv4-only network from 1980s, and all IPv6 functions, even the most basic ones, just escape their staff.

IPv6 really needs its FastTrack, as now I have been forced to throw otherwise useful RBhEX-S devices to poubelle, and replacing those with other vendor devices. And as this is completely useless work, I am sure those customers with 80-140 Mikrotiks each, are not coming back to Mikrotik. I did tell them what the issue is with the poor Mikrotik IPv6 forwarding, and they were equally pissed off that RouterOS so blatantly overlooks the huge requirement for IPv6 usability.

These customers have typically 500Mbps/500Mbps or 1000Mbps/1000Mbps internet connections, few locations have even bigger, of course with better non-Mikrotik hardware, as they do transfer a lot of 8K production quality video left and right. And yes, the sources and targets are IPv6 locations.

I know I can get some 1000 Mbps / 1000 Mbps IPv6 forwarding up, if I just will get a lot bigger router, and sacrifice the whole CPU for just IPv6 forwarding. That is not how real routers work in basic forwarding. Most of these devices have the most basic configuration, and even then, a otherwise nice and proper HEX-S is currently completely useless.

I have seen that Mikrotik does not use or know about IPv6, and within the 24 years I have been using native IPv6, the requirement for IPv6 support has been a lot more than "ooo, I can ping with IPv6!".

What is the current status, plan and prognosis of having even the most basic IPv6 forwarding to use hardware assisted FastTrack (and FastPath)?

MikroTik should just adopt XDP with hardware offloading to the NIC for packet filtering. To Adopt DPDK (or its derivatives) for packet forwarding, a lot of MikroTik boxes would be able to forward 100Gbps at near line-rate using CPU alone with XDP + DPDK.

@DarkNate: Replace XDP by VPP and keep DPDK, please! Or use all of them! :))

VyOs just transitioned from XDP to VPP and many other projects use it, to support >10G speeds.
https://wiki.fd.io/view/VPP/What_is_VPP%3F

Still, something should have already be done by MT about IPv6 performance!

DPDK/VPP is designed for packet forwarding, not packet filtering (aka firewall), for packet filtering XDP dominates the market. Just look DDoS scrubbing providers, all are using XDP in the industry for packet filtering.

It says here there is stateful filtering for VPP:
https://s3-docs.fd.io/vpp/23.10/usecases/acls.html

I don´t know what the general preference is, but what I've experenced is the successor of pfSense: TNSR, which is a damn powerful firewall and it´s based on VPP:
https://www.netgate.com/resources/artic ... rocessingl

Getting a bit offtopic, and honestly I don´t really care which solution wins. Any of those would be great!
Most importantly I want more performance out of the same amount of watts consumed.

No way. Mikrotik want to sell more Routerboard. If XDP/DPDK is used then x86 is the best choice.

XDP does not depend on any special HW: https://www.iovisor.org/technology/xdp
All new routerboards have ARM. (OK, there is maybe something I miss, but most of them have ARM.)
DPDK:
Designed to run on Arm, PowerPC and x86 processors, DPDK runs mostly in Linux userland and supports Windows. It is available for a subset of DPDK features with a FreeBSD port. DPDK is under the Open-Source BSD License.

So, MT, please give us any acceleration you can for IPv6 (and by using the previously mentioned stuff also for IPv4...), please!

Clearly, you have never spoken with Linux kernel programmers and system programmers to even understand what is XDP or DPDK, and how it is being deployed in the Telecom and data centre industry on all kinds of hardware architectures, ranging from x64 (what the actual f is x86 in 2023?) to arm64 to custom RISC-V to custom ASICs.

Cisco is adopting DPDK/VPP in some product lines, Juniper likely as well under-the-hood but closed source, Nokia already deployed XDP on their products a long time ago, VyOS is doing it with DPDK/VPP. People I know who works in Fortune 1000 companies are deploying XDP/DPDK all over their infra and server nodes on all kinds of CPU architectures, including arm64 boxes running BGP full tables on a damned SBC. AWS is doing their engineering with containers even for eBGP bilateral or PNI peering, not even physical routers, but containers!

But MikroTik:
Let's do 200Mbps IPv6, 1Gbps IPv4.

Top-notch innovation right here.

What makes you think MikroTik listens to customer demand from enterprise? They care more about SOHO market like storage features, bring the home/IoT type features etc.

Till date, they don't even support kindergarten-level routing protocol like is-is. When we all know, OSPF doesn't scale as well as is-is does.

Why do I or any enterprise use MikroTik? Because of funding problems, should we resolve funding problems, we're going straight for Nokia or Juniper. Heck, might as well buy an MX204 refurbished for my home lab.

[What makes you think MikroTik listens to customer demand from enterprise? They care more about SOHO market like storage features, bring the home/IoT type features etc.
Sorry sir: strictly home user of Mikrotik here! I had my share of enterprise networks, but none of that had anything to do with MT.
I doubt MT cares only about SOHO, MT cares about any market which they can make profits from, as any other profit oriented company.
Till date, they don't even support kindergarten-level routing protocol like is-is. When we all know, OSPF doesn't scale as well as is-is does.
Well, it surely takes some serious efforts to implement that "kindergarten-level" IS-IS (just the ISO standard on ISIS has around 200pages), and they look like to roll their own implementation and they for sure are working on it a lot. Btw. OSPF is good enough to scale to many hundreds of routers. You just have very fast CPUs with lots of RAM nowadays. OSPF is still widely used in enterprises.
Why do I or any enterprise use MikroTik? Because of funding problems, should we resolve funding problems, we're going straight for Nokia or Juniper.
The more you save, the more you profit in many cases. I see also more benefits, like low power, small size, versatility, supported for ages.
I have seen many enterprises giving up on separate, out-of-band management networks, because of the costs of the networking HW.
This use case would be a perfect fit for MT even in big companies!
Heck, might as well buy an MX204 refurbished for my home lab.
I belive that would cost a bit more (maybe 5x?) than a brand new rb5009 and it has something like 650W PSUs, fans, also the weight ? OK you would be well served with it's 400GB routing throughput. (??)
No MT does not compete directly with Juniper.
In smaller scale, it enables deploying faster networks at remote locations and most importantly it has enabled my 10G NAS connection.
But speed (also price, power, size) matters here in SOHO as well, as many places already get >=1G Internet connections for private users.
IPv6 is also important here in SOHO, probably even more than in datacenters.

OSPF is a PITA. is-is isn't.

OSPF requires operational and configuration overhead when you have 1000 layer 3 devices in a network, to maintain the configuration automation template etc, across IPv4 and IPv6.

Whereas with is-is, since it's CLNP, I don't need IP addressing whatsoever for underlay network, it can run unnumbered with a single-instance. Minimises operational and configuration expenses.

If OSPF is so great, why is there no Tier 1 carrier using it instead of is-is?

OSPF requires operational and configuration overhead when you have 1000 layer 3 devices in a network, to maintain the configuration automation template etc, across IPv4 and IPv6.
I did not say, that OSPF is in any way better than ISIS. It is still a fact, that in enterprise networks OSPF is still in use and scaling got much less an issue with as much resources we have today in any router.
So probably current support for routing protocols is no reason for MT to get used more in those networks. And Tier 1 Provider are really no market for MT.

In contrast: low IPv6 performance is very well a reason for not buying MT in SOHO and in Enterprise markets!

The majority of network engineers disagrees with you:

Hmmm, I did not read every post in that thread, but after a quick look:
THAT thread is about the benefits of ISIS and there the network engineers do discuss benefits of implementing ISIS.
I still never said anything about OSPF being better or ISIS being inferior.

In this thread the goal is to discuss IPv6 support and I believe IPv6 performance is BAD on MT. MT should try to do something about that, before implementing another routing protocol. Especially if they would speed up the whole data plane in the process!
That's my opinion and a 100 network engineers could not beat it out of me.
At least I´d try to run away.

Speaking about VyOs, old ER-4 can forward established TCP IPv6 at line speed (gigabit) with less than 2% CPU utilization. Too bad their os is abandonware.
Old ER-4, and even older ER-Lite, were using Cavium SDK (proprietary) to offload established connections to hardware (Octeon SoC).
It isn't pure SW optimization (like MT fast-track, or VPP), and it is not either a true L3HW. Something in between.

The complexity of this implementation was so high that EdgeOS v.2.x took years to reach stable, with a history of long-lasting bugs (packet re-ordering, ipsec, ...), as SoC vendor (cavium) was not willing/able to provide modules for recent linux kernel.

Likely it was one of the reasons they terminated the EdgeRouter line.

I have to agree, as early as 2015 (even before ?), small ER-lite managed to forward 1Gbps (IPv4 + Ipv6) with near-zero CPU usage.

Of course this (the above) is also a lesson learned by MikroTik, and likely the reason why such things are not incorporated that quickly anymore.
See how it went with the long release delay of RouterOS v7 (updating the heavily patched Linux kernel was a major effort), and what is happening now with Wireless (maintaining the old wireless driver became too much work and now that a standard driver from the manufacturer is used, a lot of functionality is lost).
And MikroTik use many different CPU and SoC architectures and should they implement IPv6 fasttrack only for e.g. CCR20xx the howling here would be even worse than it is now.
