It seems silly for the first moment, but it has several advantages. IPv4 and IPv6 usually needs slightly different configs, different filters (esp. addresses in filters) and having separate IPv4 sessions and IPv6 sessions means that you forward IPv4/6 routes only if IPv4/6 is really working on the routers.
And what about BGP+ announcing IPv6 prefixes over IPv4 connection?
I am not sure what kind of answer you would expect. BIRD (AFAIK) supports announcing IPv6 over IPv4 connection, but it is not a suggested configuration. Because if bird6 is listening also on IPv4 socket, you cannot start bird4 on the same address/iface. And also it can forward IPv6 routes even if IPv6 is not really working on the router. -- Elen sila lumenn' omentielvo Ondrej 'SanTiago' Zajicek (email: santiago@crfreenet.org) OpenPGP encrypted e-mails preferred (KeyID 0x11DEADC3, wwwkeys.pgp.net) "To err is human -- to blame it on a computer is even more so."
