Lastly, there's a hidden bit here many people haven't dealt with yet in lab networks. In IPv4 critical environments it's typical to use HSRP or VRRP to provide a single gateway across two routers. The IPv6 way to do this is to have both advertise RA's, possibly with different priorities.Erm, I thought the IPv6 way to do it was to use IPv6 VRRP... I've heard of some vendor bugs on it, but it's implemented.
You can do VRRPv6 (now, finally, on some platforms). However, the standard way this works is, wait for it, advertising the default gateway via RA's! At least you can static route to the VRRPv6 address and that works without RA's. Again, it would be nice to give out the address in DHCPv6 and not need RA's at all, but alas there is no default route field in DHCPv6. -- Leo Bicknell - bicknell () ufp org - CCIE 3440 PGP keys at http://www.ufp.org/~bicknell/
