Need information/document on IPv6 support for vrrp .
Above IPv6 configuration guide do not mention any IPv6 & VRRP stuffs. ( is it supported ? )
with stateless autoconfiguration and router advertisements the only possible benefit of HSRP, GLBP and eventually VRRP is a quicker convergence.
Router advertisements ICMPv6 messages are enough to make hosts aware of gateways on the wire.
VRRP is standards based and a draft about VRRP version3 for both IPv4 and IPv6 has been published
it has been just published Oct 23 2009 so I think VRRP for IPv6 will be introduced when this draft will become an RFC
Hope to help
