Hoi Ondrej, Bird users,

TL/DR: Ondrej's patch works and allows Bird to use OSPFv3 with either 
completely unnumbered interfaces, where it 'borrows' a valid IPv4 
address from a loopback device. It does so without breaking RFC5838!

I will then check to see if VPP is happy to set the correct nexthop 
(both in Bird2, but also in the VPP FIB).
I'll report back after the weekend but thank you very much for working 
on this (and/or the extended next hop feature).


- It now also works when interfaces have duplicate IP addresses.
- For the VPP aficionados, both scenario's work with 'set interface 
unnumbered' and with or without 'lcp lcp-sync-unnumbered' (once my 
commits to VPP are merged).


I tested both scenarios above:
- Scenario 1: where e0/e1 have the same IPv4/IPv6 address as loop0
- Scenario 2: where e0/e1 are left unconfigured, and OSPFv3 finds a 
nexthop from loop0

Don’t know why it was set this way but now it should work, please 
check if you can.

I can confirm the wiki now works.

Hello!

If you meant this wiki
https://gitlab.nic.cz/labs/bird/-/wikis/home
it's still there, just quite old.

Could you please share with us what you were looking for and on which links? 
Without that, we can't move forward.

Thanks,

Hello!

If you meant this wiki

it's still there, just quite old.

Could you please share with us what you were looking for and on which links? 
Without that, we can't move forward.
