Hi,
is it possible to only announce IPv6 RA if you receive a default route via another protocol in bird?
This is not currently possible, but it is simple feature that i already wanted to implement, so could be expected in near future. Question is how exactly such feature should behave - you could either withdraw just default route on IPv6 clients, or you could also deprecate assigned IPv6 addresses. The first behavior is simple and probably useful in most cases, but it does not help in a case when you have two (or more) completely independent uplinks (with different assigned IPv6 prefixes), i.e. non-BGP based multihoming. In that case you would need rules like like 'propagate this prefix if you received default route from that protocol'. Perhaps we could just have prefix-specific filters that decide whether given prefix should be propagated or not (based on received (default) routes). -- 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."
