Examples of Configuring VRRP for IPv4 and IPv6

The following example shows configuring VRRP for IPv4 Router 2.

R2(conf)#interface twentyFiveGigE  2/31
R2(conf-if-tf-2/31)#ip address 10.1.1.1/24
R2(conf-if-tf-2/31)#vrrp-group 99
R2(conf-if-tf-2/31-vrid-99)#priority 200
R2(conf-if-tf-2/31-vrid-99)#virtual 10.1.1.3
R2(conf-if-tf-2/31-vrid-99)#no shut

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 interface has a higher IPv6 address than the twentyFiveGigE 1/2 interface on R3.

Router 2
R2(conf)#interface twentyFiveGigE 1/1
R2(conf-if-tf-1/1)#no ip address
R2(conf-if-tf-1/1)#ipv6 address 1::1/64

R2(conf-if-tf-1/1-vrid-10)#virtual-address 1::10
R2(conf-if-tf-1/1-vrid-10)#no shutdown
R2(conf-if-tf-1/1)#show config
