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 ??

Subject: Re: [FROG] Binding two IP addresses to bgpd

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,

-Matt
