Generates a virtual link-local IPv6 address and assigns it as the virtual IPv6 address for a VRRPv3 instance.
VRRP sub-configuration mode
The no form of this command deletes the auto-generated virtual link-local IPv6 address for the VRRP v3 instance.
The default VRRPv3 implementation allows only the link-local address that is configured on a physical interface to be used as the virtual IPv6 address of a VRRPv3 instance. This limits configuring a link-local address for each VRRP instance on the same physical interface because there can be only one link-local address per physical interface. You can use this command on the owner or backup router to generate a virtual link-local IPv6 address from the virtual MAC address of a VRRPv3 instance and assign it as the virtual IPv6 address for the VRRPv3 instance. This auto-generated link-local IPv6 address is not linked to any physical interface on the router.
The following example generates a virtual link-local IPv6 address and its allocation as the virtual IPv6 address of a VRRPv3 cluster on an owner router.
device(config)# interface ve 3
device(config-vif-3)# ipv6 vrrp vrid 2
device(config-vif-3-vrid-2)# owner
device(config-vif-3-vrid-2)# ipv6-address auto-gen-link-local
device(config-vif-3-vrid-2)# activate
