Figure 150. Example of VRRP for an IPv6 Configuration
NOTE: In a VRRP or VRRPv3 group, if two routers come up with the same priority and another
router already has MASTER status, the router with master status continues to be MASTER even if one
of two routers has a higher IP or IPv6 address.
The following example shows configuring VRRP for IPv6 Router 2 and Router 3.
Configure a virtual link local (fe80) address for each VRRPv3 group created for an interface. The VRRPv3
group becomes active as soon as you configure the link local address. Afterward, you can configure the
group’s virtual IPv6 address.
The virtual IPv6 address you configure must be the same as the IPv6 subnet to which the interface
belongs.
Although R2 and R3 have the same default, priority (100), R2 is elected master in the VRRPv3 group
because the GigE 0/0 interface has a higher IPv6 address than the GigE 1/0 interface on R3.
Router 2
R2(conf)#interface tengigabitethernet 0/0
R2(conf-if-te-0/0)#no ip address
R2(conf-if-te-0/0)#ipv6 address 1::1/64
R2(conf-if-te-0/0)#vrrp-group 10
