Configuring VRRP

VRRPv3 Application Example

OmniSwitch AOS Release 6 Network Configuration Guide

page 32-31

Note. The same VRRPv3 configuration must be set up on each switch. The VRRPv3 router that contains, 
or owns, the IPv6 address will automatically become the master for that virtual router. If the IPv6 address 
is a virtual address, the virtual router with the highest priority will become the master router.

In this scenario, the master of VRID 1 will respond to neighbor solicitation with a neighbor advertisement 
for IPv6 address A using the virtual router MAC address for VRID 1 (00:00:5E:00:02:01). OmniSwitch 1 
is the master for VRID 1 since it contains the physical interface to which 

213:100:1::56

s assigned. If 

OmniSwitch A should become unavailable, OmniSwitch B will become master for VRID 1.

In the same way, the master of VRID 2 will respond to neighbor solicitation for IPv6 address B using the 
virtual router MAC address for VRID 2 (00:00:5E:00:02:02). OmniSwitch B is the master for VRID 2 
since it contains the physical interface to which 

213:100:1::57

 is assigned. If OmniSwitch B should 

become unavailable, OmniSwitch A will become master for 

213:100:1::57

. This configuration provides 

uninterrupted service for the end hosts.

The figure below shows two VRRPv3 routers with two virtual routers backing up one IPv6 address on 
each VRRPv3 router respectively. Virtual router 1 serves as the default gateway on OmniSwitch A for 
clients 1 and 2 through IPv6 address 

213:100:1::56

. For example, if the port that provides access to the 

Internet on OmniSwitch A fails, virtual router 1 will continue to be the default router for clients 1 and 2, 
but clients 1 and 2 will not be able to access the Internet.
