Hello Satish,

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.

see

http://www.ietf.org/dyn/wg/charter/vrrp-charter.html

VRRP is standards based and a draft about VRRP version3 for both IPv4 and IPv6 has been published

http://www.ietf.org/id/draft-ietf-vrrp-unified-spec-04.txt

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

Giuseppe
