Configuring VRRP VRRP Application Example
OmniSwitch AOS Release 6 Network Configuration Guide September 2009 page 32-27
The CLI commands used to configure this setup are as follows:
1 First, create two virtual routers for VLAN 5. (Note that VLAN 5 must already be created and available
on the switch.)
-> vrrp 1 5
-> vrrp 2 5
2 Configure the IP addresses for each virtual router.
-> vrrp 1 5 ip 10.10.2.250
-> vrrp 2 5 ip 10.10.2.245
3 Enable the virtual routers.
-> vrrp 1 5 enable
-> vrrp 2 5 enable
Note. The same VRRP configuration must be set up on each switch. The VRRP router that contains, or
owns, the IP address will automatically become the master for that virtual router. If the IP 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 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 unavail-
able, 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 unavail-
able, OmniSwitch A will become master for 10.10.2.245. This configuration provides uninterrupted
service for the end hosts.
