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 ??

Can you elaborate a bit on your use case so we can understand what the goal is?

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.)
