Re: MPLS hardware forwarding on new switches?

Doing MPLS/VPLS and VXLAN in Hardware on switches is a HUGE opportunity for Mikrotik to carve out a niche. I know if this was supported, I wouldn't be buying 1 or 2 switches per year, it would be hundreds if not thousands of switches per year. Couldn't agree with you more...nobody has VXLAN in anyt...

Re: Static routing instead of OSPF

OSPF is incredibly resilient to routing loops unless you're redistributing prefixes and have a config or design issue. It is the backbone of almost every network we work on for MikroTik - whether by itself or as the transport for iBGP and MPLS/LDP. It sounds like you may have a config or other issue...

Re: MPLS - massive throughput difference on CHR when using explicit nulls

I moved my lab to Hyper-V Core 2012 R2, and can confirm that MPLS runs fine on that. That's great info...we did a bunch of CHR testing on different hypervisors for BGP and presented the results in Berlin at MUM Europe 2018. Hyper-V was way better than ESXi and ProxMox (KVM) by a significant margin.

IS-IS can scale much larger than OSPF due to the way it designs the hierarchy of flooding domains and by using Incremental SPF.

Re: MPLS, BGP and OSPF design for wisp

Your BGP peer remote-addresses are wrong. These should be the peer's address on the /30 links.

Not true...in an iBGP design you want the peering address to use loopbacks that are advertised by OSPF so that if an interface goes down and another path is available, the peering will stay online.

You have a static route set for the gateway of 2a01:4a0:4a::1/128 istead of using the directly connected route. That forces the MT to use routing recursion which is not yet supported in RouterOS for IPv6. Try removing the static route and see if the defualt route for global unicast goes active.
