Enabling an IPv6 VRRP-Ev3 device

This task is performed on any device that is designated as a VRRP extended version 3 (VRRP-Ev3) device. For each VRRP-Ev3 virtual routing instance, there is one master device and all other devices are backups; but, unlike VRRPv3, every device is configured as a backup and the device with the highest priority becomes the master device. Repeat this task for all devices that are to be designated as VRRP-Ev3 devices.
NOTE
Only VRRPv3 or VRRP-Ev3 can be enabled in your network.
  1. On the device designated as a VRRP-Ev3 device, from privileged EXEC mode, enter global configuration mode by issuing the configure terminal command. 
    device# configure terminal
  2. Globally enable VRRP-Ev3. 
    device(config)# ipv6 router vrrp-extended
  3. Configure the Ethernet interface link. 
    device(config-ipv6-vrrpe-router)# interface ethernet 1/1/7
  4. Configure the IPv6 address of the interface. All devices configured for the same virtual router ID (VRID) must be on the same subnet. 
    device(config-if-e1000-1/1/7)# ipv6 address fd4b::4/64
  5. Assign the device to VRID 4. 
    device(config-if-e1000-1/1/7)# ipv6 vrrp-extended vrid 4
    NOTE
    You can assign a VRID number in the range of 1 through 255.
  6. Designate this router as a backup VRRPv3 device. All VRRP-Ev3 devices are initially configured as backup devices; the device with the highest priority assumes the role of master device. 
    device(config-if-e1000-1/1/7-vrid-4)# backup priority 110
    While configuring a backup device, you can set a priority that is used when the designated master VRRP device goes offline. The backup device with the highest priority will assume the role of master device.
  7. Configure the VRRP version. 
    device(config-if-e1000-1/1/7-vrid-4)# version 3
  8. Configure an IPv6 link-local address for the VRID. 
    device(config-if-e1000-1/1/7-vrid-4)# ipv6-address fe80::768e:f8ff:fe2a:0089
  9. Configure a global IPv6 address for the VRID. 
    device(config-if-e1000-1/1/7-vrid-4)# ipv6-address fd4b::99
    The IPv6 address associated with the VRID must not be configured on any of the devices used for VRRP-Ev3.
  10. Enable the VRRP session. 
    device(config-if-e1000-1/1/7-vrid-4)# activate

The following example configures a backup VRRP-Ev3 device. 

device# configure terminal
device(config)# ipv6 router vrrp-extended
device(config-ipv6-vrrpe-router)# interface ethernet 1/1/7
device(config-if-e1000-1/1/7)# ipv6 address fd4b::4/64
device(config-if-e1000-1/1/7)# ipv6 vrrp-extended vrid 4
device(config-if-e1000-1/1/7-vrid-4)# backup priority 50
device(config-if-e1000-1/1/7-vrid-4)# version 3 
device(config-if-e1000-1/1/7-vrid-4)# ipv6-address fe80::768e:f8ff:fe2a:0089
device(config-if-e1000-1/1/7-vrid-4)# ipv6-address fd4b::99
device(config-if-e1000-1/1/7-vrid-4)# activate
