FRR BGP ipv6-auto-ra

https://docs.frrouting.org/en/latest/bgp.html#clicmd-bgp-ipv6-auto-ra

Please add a no-ipv6-auto-ra option to the BGP parameters because FRR is sending RA packets with different settings on my intranet at the same time as radvd!

All tasks should be on our forge if you want a new feature.
I created the task/feature request ⚓ T7531 Add FRR no-ipv6-auto-ra option
Thanks!

Comparing to other vendors this should be configured on interface level and not in the “router bgp” settings.

Do you know if FRR supports it?

No idea, it seems like its a global option according to BGP — FRR latest documentation

However according to this support ticket it seems like you can define interface configuration in FRR aswell:

So I would vote for having that statically disabled (as in “no bgp ipv6-auto-ra”) and let radvd (or whatever is used) to deal with sending RA’s at interface level?

Also relevant cases:

suppress-ra can currently be configured at the interface level in FRR, but this setting is overridden by bgpd if extended-nexthop is enabled

https://docs.frrouting.org/en/latest/ipv6.html#clicmd-ipv6-nd-suppress-ra

I also tested it and it does

And no bgp ipv6-auto-ra will disable this behaviour completely from FRR/bgpd ?

Yes, setting no bgp ipv6-auto-ra will no longer cause the FRR to send RA packets just because the Extended Next Hop in BGP is enabled

Maybe in the future VyOS should remove radvd and use FRR included features instead
