Configuring VRRP VRRPv2 Application Example
OmniSwitch AOS Release 8 Network Configuration Guide December 2017 page 23-21
In this scenario, the master of VRID 1 will respond to ARP requests for IP address A using the virtual
router MAC address for VRID 1 (00:00:5E:00:01:01). OmniSwitch 1 is the master for VRID 1 since it
contains the physical interface to which 10.10.2.250 is 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 ARP requests for IP address B using the virtual
router MAC address for VRID 2 (00:00:5E:00:01:02). OmniSwitch B is the master for VRID 2 since it
contains the physical interface to which 10.10.2.245 is assigned. If OmniSwitch B should become
unavailable, OmniSwitch A will become master for 10.10.2.245. This configuration provides
uninterrupted service for the end hosts.
VRRPv2 Tracking Example
The figure below shows two VRRP routers with two virtual routers backing up one IP address on each
VRRP router respectively. Virtual router 1 serves as the default gateway on OmniSwitch A for clients 1
and 2 through IP address 10.10.2.250 and virtual router 2 serves as default gateway on OmniSwitch B for
clients 3 and 4 through IP address 10.10.2.245. 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.
In this example, the master for virtual router 1 has a priority of 100 and the backup for virtual router 1 has
a priority of 75. The virtual router configuration for VRID 1 and 2 on VRRP router A is as follows:
-> vrrp 1 5 priority 100 preempt
-> vrrp 2 5 priority 75
