Configuration examples
Configuring Switch 1
To configure VRRP Switch 1, enter the following commands.
NOTE
When you configure the Master (Owner), the address you enter with the ip-address command must
already be configured on the interface.
Configuring Switch 2
To configure Switch 2 in Figure 185 on page 1651 after enabling VRRP, enter the following
commands.
The backup command specifies that this router is a VRRP Backup for virtual router VRID1. The IP
address entered with the ip-address command is the same IP address as the one entered when
configuring Switch 1. In this case, the IP address cannot also exist on Switch 2, but the interface
on which you are configuring the VRID Backup must have an IP address in the same subnet. By
entering the same IP address as the one associated with this VRID on the Owner, you are
configuring the Backup to back up the address, but you are not duplicating the address.
NOTE
When you configure a Backup router, the router interface on which you are configuring the VRID
must have a real IP address that is in the same subnet as the address associated with the VRID by
the Owner. However, the address cannot be the same.
The priority parameter establishes the router VRRP priority in relation to the other VRRP routers in
this virtual router. The track-priority parameter specifies the new VRRP priority that the router
receives for this VRID if the interface goes down. Refer to “Track ports and track priority” on
page 1654.
The activate command activates the VRID configuration on this interface. The interface does not
provide backup service for the virtual IP address until you activate the VRRP configuration.
Alternatively, you can use the enable command. The activate and enable commands do the same
thing.
