OSPFv3 between BIRD2 and RouterOS (Mikrotik)

[Kees Meijs | Nefos]

Hi list,

First of all: I'm very sorry if this has been discussed before.

Anyway, we're experiencing possible (configuration) incompatibiliy 
between BIRD2 and Mikrotik RouterOS. To be precise, we're on BIRD 2.0.7 
and RouterOS 6.48.5 (Level 6).

Configuration snippet from BIRD:

> protocol ospf v3 ospf_v6 {
>         # Do not generate ECMP (equal-cost multipath) routes.
>         ecmp no;
>
>         area 0.0.0.0 {
>                 interface "eth0" {
>                         authentication cryptographic;
>                         password "SOMETHING";
>                         bfd yes;
>                 };
>
>                 interface "eth1" {
>                         authentication cryptographic;
>                         password "SOMETHINGELSE";
>                         bfd yes;
>                 };
>
>                 interface "dummy0" {
>                         stub;
>                 };
>
>                 interface "eth2" {
>                         stub;
>                 };
>
>                 interface "eth3" {
>                         type pointopoint;
>                         bfd yes;
>                 };
>         };
> }

The dummy0 interface has bound a /32 IPv4 and a /128 IPv6 address for 
BGP lookback. OSPFv3 should provide us with IGP in order to facilitate iBGP.

Between BIRD nodes this works flawless.

When adding the Mikrotik router to the mix, the /128 addresses don't get 
propagated. Other routes do and OSPFv3 seems to work fine, but the stub 
routes seem to be ignored.

What am I missing here?

Thanks!

Cheers,
Kees
