I'm also interested to see an example config for this. I tried using a v4 AFI over an IPv6 only peering back in 7.3 but wasn't able to make it work and didn't have time to troubleshoot. From what I can tell this is still not working as of v7.7beta8. Mikrotik opened two bugs, and I haven't gotten no...

I was doing this pretty late at night and think I was a bit sleep deprived. Thinking about it with a clearer head in the morning, of course there’s no IPv4 NEXT_HOP because there’s no configured IPv4 address to use. Does your configuration have at least one IPv4 address configured to use as transpo...

Config depends on the setup but in any case nexthop can be adjusted with routing filters. It is also not limited just to BGP, you can add IPv4 static routes with IPv6 gateways. Can you provide an example of this? I have tested setting static IPv6 nexthops {set gw} on afi4 routes, which will go acti...

ROSv6 had hacks to guess what ipv6 nexthop to set automatically. In case of eBGP on a shared network it is easy and we can get and use link-local address, which we will add as a feature in the future. But in other cases you would still need to adjust nexthop with routing filters according to your n...

I see that RFC5549 is now listed as supported at least since v7.1 here https://help.mikrotik.com/docs/display/ ... l+Overview but have found no other mentions. Is there a configuration guide or feature description, or is it as simple as passing AFI v4 over a v6 peering?

Guys, RIP routing protocol on ROS v7 is still not working. You mentioned in the changelog that RIP is supported but in fact it is not operational. I have made the tests and routes are not being learned. Can you please fix this issue ASAP? Thanks. maherhaddad, did you get any further with this? I've...

Performance isn't amazing — I'm getting about 14.5 Mbps (iperf3 tcp) with NAT to ZT hosts sharing a LAN interface with an RB3011 running RC2. Anyone getting better? Regardless, this is super useful and cool. [ ID] Interval Transfer Bitrate [ 5] 0.00-1.00 sec 2.00 MBytes 16.8 Mbits/sec [ 5] 1.00-2.00...

According to https://help.mikrotik.com/docs/display/ROS/v7+Routing+Protocol+Status RIP and OSPF should be functional under 7.1beta4. However, I've tested on RB3011, CRS309, and CCR1009, with fiber, copper, and DAC at 1 and 10G, and have suffered abject failure. OSPFv3 results in the following in the...

Steveocee, That's cool that fq_codel works on a Hex. Are you able to determine whether it uses more, or less CPU, than your large queue tree, or is that not a fair comparison? Jeremy Upgraded my Hex last night and removed my extremely large queue tree for a simple FQ_CoDel queue. So far so good, onl...

It's not possible to use Mikrotik in a real production-quality dual-stack service provider network without working BGP. I'd hate to see the CCR series, for example, be left out in the cold, if we have to wait for an entirely new generation of hardware to get ROS7. Not to spread FUD, but I don't have...

You might create a temporary workaround by setting up an EoIP or VPLS tunnel over the wirless link. Both tunnel types support fragmentation and reassembly Thanks, sup5. In this case, I am using the wireless wire as trunks in a TRILL mesh, and TRILL adds headers already. So I need to be able to set ...

Hi Tomas. I have started a ticket already. I hoped someone else might have seen this as well. In the context of any type of encapsulation, the actual configured MTU is somewhat misleading. The bridge will attempt to forward the packet, and the link crashes. There is no way to filter out the packet u...

The plot thickens further. On both current and rc builds, Wireless Wire has an issue at any MTU over 1704. To replicate, set L2/L3 MTU on Wireless Wire eth1 and w60 interfaces to Nominal MTU. Send a packet through the bridge larger than Actual MTU, and the link will go down. Nominal MTU — Actual MTU...

I've been testing Wireless Wire with Ignitenet's Meshlinq (TRILL) switches in the lab. Version: current 6.42.6 Current 60Ghz max L2 MTU is 2290. Sending a decapsulated ICMP packet to the Wireless Wire nodes of > 2264 (including headers) causes a 60 Ghz link down event! In practice, this limit is eve...

Derrick, I was thinking about extending the idea of the virtual interfaces to OSPF. Doing something like monitoring adjacency count, and downing the bridge using a timer (for detecting flapping). Have you tried this?

I'm interested in this as well — have been for a few years now.

I've been working on a pseudo-manual method using MPLS-TE, BGP communities, and link coloring to "manually" make more preferred paths for traffic-of-interest, overriding OSPF costs.

Does this interest you?

ZeroByte, thanks for the detailed comments. After further testing, I have reached the same conclusions you have. I would rather not tunnel — although I did briefly contemplate a full-mesh MPLS/VPLS for directly peering each IPv6 router. (Traffic queue management would be just one problem with that d...

Hi The only workaround we have seen so far for iBGP IPv6 routes to get active is to add a static ipv6 route for the loopback IP for the next-hop delivered through the route-reflectors. (again tested with RouterOS 6.40.2) hk Let me recap, and please correct me if I'm wrong. 1. Under no circumstances...

I had this script working briefly, but now in ROS 6.37.1 and 6.38.1 I get no results for /log find, in any iterations. How about you?

I think the problem is that "/log find" is broken.

/log find topics~"info"
/log find where topics~"info"

Both return no entries in 6.37.3 or 6.38.1

I run a BGP session over an L2TP tunnel. Normally this works fine. Occasionally though, one end of the peer (the L2TP client end) will end up with the tunnel established, but the BGP peer stuck in 'open sent'. When this happens, the only recourse is to bounce the BGP peer (disable/enable.) This peer...

You need to get lower-level technical specs for the VPN in order to be able to setup your router. There probably exists a document that lists these specs. These are available; look for the compatibility settings for Google Cloud VPN + AWS. I got as far as phase 2, and SAs installed, but then ran in...

Model CCR1016-12S-1S+ (similar results on a  CCR1009)
Queue tree + mangle + some firewall rules, udp 1500 bytes, SEND, on a 10G DAC with max-limit=1000M
Queue disabled = ~1000Mbps
6.34.6 = ~823 Mbps
6.35.4 = ~725 Mbps
6.36rc28 = ~698 Mbps

Same problem here - a (new) CCR-1009-PC of which ether3 seems fried. Also on newest firmware and ROS version.. In my particular case, it came out of the box with all ports working — it's that they died almost immediately. Basically in the configuration phase. I came back the next morning, and an ad...

I guess the appropriate question is when should I RMA them? Frustrating if I can't trust them out of the box. I'm a long way from anywhere and from what I hear RMA is often not worth it. Advice?

Are CCR ethernet port failures common? I've never seen this behavior before with new devices in a properly grounded equipment rack. CCR1009-8G-1S-1S+ Port ether1, failure to reach 1G (with auto on or off), 100 only Port ether4 failed when connected to CCR1009-8G-1S, still dead CCR1009-8G-1S Port eth...

Ubiquiti has admitted that they are not passing these packets. They'll look into allowing them. (The RFC implies that they should be passed, but does not make it explicit.)

Do you have a packet capture? Does the Ethernet Header look 'normal' ?

I will capture packets tomorrow. In UBNT forums, I found another user with the same issue. Will report in both places.

Has anyone had trouble getting RoMON to work when passed through a PoE EdgeSwitch 24? It's managed, and all I have are some VLANs configured. Full 1500-byte packets no problem, everything else working fine. No RoMON neighbours though, not with HAP lite, CRS, RB2011, or x86. When connected directly, ...

I've got a VRRP interface on a gigabit Ethernet port. SNMP appears to be reporting a default speed for it of 10Mbps. IF-MIB::ifSpeed.16 = Gauge32: 10000000 Its parent interface shows as IF-MIB::ifSpeed.3 = Gauge32: 1000000000 There appears to be no way to set this administratively. Needless to say t...
