Hello, This is a feature that I'd dearly like to have also. In my setup, we run two routing agents, bird and frr. Bird is used by Calico to form an overlay on its own. frr provides actual routing for the host. Since frr's bgpd binds to 0.0.0.0:179, bird isn't able to run even if it's set to listen on a specific interface. The workaround I used is to change the listen port on one of them, which isn't the most ideal. Regards, Derrick On Thu, Feb 4, 2021 at 4:45 AM Novak, Jan <jan.novak@intl.att.com> wrote:
Hi,
This is just from an user point/config view. I haven’t tried with FRR but other network Oss allow simultaneous BGP sessions with IPv4/IPv6 addresses
For its sessions. The use case would be an ordinary dual stack router or sometimes transporting IPv6
AF across IPv4 session and vice versa ??

I don't believe this is possible. Can you elaborate a bit on your use case so we can understand what the goal is?

Apologies if I’m missing something easy here — I think I’ve looked at this for too long.
I want my bgpd process to listen to 2 IP addresses — one IPv4 and one IPv6. I cannot find a syntax that allows this to happen. I can listen to one or the other. I really don’t want to run two bgpd processes to accomplish it. (I could let it bind to the default 0.0.0.0 / :: and use a firewall, but, again, I’d rather just bind to the two addresses I need it on, if possible.)
Thanks,
