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.
Note: Only 16 VRRP instances are configurable on the ICX 7150 device.
  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 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.
  8. 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)# ipv6-address fd4b::99
device(config-if-e1000-1/1/7-vrid-4)# activate
VRRP-E router 4 for this interface is activating
