[FROG] Binding two IP addresses to bgpd

Thanks for responding; sorry for the belated reply.

I have a machine with two different interfaces (one private, one public), each with an IPv4 and an IPv6 address.  I want to listen only on the private interface.  By default, it binds to * and listens on both interfaces.  I can get it to listen to *just* the IPv4 on my private interface, or just the IPv6, but not both without it also listening on the public interface.

Thanks,

-Matt

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.)
