Enabling an IPv6 VRRPv3 backup device

This task is performed on all devices that are designated as backup VRRPv3 devices. Initially a backup priority is set to 100. For each VRRPv3 session, there are master and backup routers, and the IPv6 address assigned here to the VRID is the IPv6 address of the master router. The task is repeated on each backup VRRPv3 device with corresponding changes to the interface number and IPv6 address of the interface.

Note: When implementing IPv6 VRRPv3 across a network with devices from other vendors, be aware of a potential interoperability issue. RUCKUS has implemented IPv6 VRRPv3 functionality to comply with RFC 5798 and will interoperate well with other vendors that support RFC 5798.
Note: Only 16 VRRP instances are configurable on the ICX 7150 device.
  1. On the device designated as a backup VRRPv3 device, from privileged EXEC mode, enter global configuration mode by issuing the configure terminal command. 
    device# configure terminal
  2. Globally enable IPv6 VRRP. 
    device(config)# ipv6 router vrrp
  3. Configure the Ethernet interface link for the owner device. 
    device(config-ipv6-vrrp-router)# interface ethernet 1/1/4
  4. Configure the IPv6 address of the interface. 
    device(config-if-e1000-1/1/4)# ipv6 address fd2b::3/64
  5. Assign the backup device to the virtual router ID (VRID) 2. 
    device(config-if-e1000-1/1/4)# ipv6 vrrp vrid 2
    Note: You can assign a VRID number in the range of 1 through 255.
  6. Designate this router as a VRRPv3 backup device and assign it a priority of 100. 
    device(config-if-e1000-1/1/4-vrid-2)# backup priority 100
  7. Configure the VRRP version. 
    device(config-if-e1000-1/1/4-vrid-2)# version 3
  8. By default, backup VRRP devices do not send hello messages to advertise themselves to the master. Use the following command to enable a backup router to send hello messages to the master VRRP device. 
    device(config-if-e1000-1/1/4-vrid-2)# advertise backup
  9. Assign the IPv6 link-local address to the VRID for use in the local network. 
    device(config-if-e1000-1/1/4-vrid-2)# ipv6-address fe80::768e:f8ff:fe2a:0099
  10. Assign the global IPv6 address to the VRID. 
    device(config-if-e1000-1/1/4-vrid-2)# ipv6-address fd2b::2
  11. Enable the VRRP session. 
    device(config-if-e1000-1/1/4-vrid-2)# activate

The following example configures an IPv6 VRRPv3 backup device. 

device# configure terminal
device(config)# ipv6 router vrrp
device(config-ipv6-vrrp-router)# interface ethernet 1/1/4
device(config-if-e1000-1/1/4)# ipv6 address fd2b::3/64
device(config-if-e1000-1/1/4)# ipv6 vrrp vrid 2
device(config-if-e1000-1/1/4-vrid-2)# backup priority 100
device(config-if-e1000-1/1/4-vrid-2)# version 3
device(config-if-e1000-1/1/4-vrid-2)# advertise backup
device(config-if-e1000-1/1/4-vrid-2)# ipv6-address fe80::768e:f8ff:fe2a:0099
device(config-if-e1000-1/1/4-vrid-2)# ipv6-address fd2b::2
device(config-if-e1000-1/1/4-vrid-2)# activate
