VRRP
Router Configuration Guide 413
One exception to this rule is for the IPv6 link-local address that is configured as a backup
address. The same link-local address can be configured in all virtual routers that use the same
vrid.
Virtual Router IP Address Assignment without Parent IP Address — When assigning an IP
address to a virtual router instance, an associated IP address (see backup and backup) on the
parental IP interface must already exist. If an associated IP address on the parental IP interface
is not configured, the virtual router IP address assignment fails.
Virtual Router IPv6 Address Assignment — An IPv6 backup address requires that the parental
IP address that is in the same subnet as the backup address must be manually configured, non-
EUI-64 and configured to be in the preferred state.
Parameters ipv6-address — The virtual router IP address expressed in dotted decimal notation. The IP virtual
router IP address must be in the same subnet of the parental IP interface IP address or equal
to one of the the parent interface addresses for owner virtual router instances.
