Figure 178. 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
TenGigabitethernet 1/1/1/1 interface has a higher IPv6 address than the TenGigabitethernet 1/1/2/1 interface
on R3.
