Configuring Router1
To configure VRRP Router1, 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.
The ip vrrp owner command specifies that this router owns the IP address you are associating with
the virtual router. Because this router owns the IP address, this router is the default Master router
and its VRRP priority is thus 255.
Configuring Router2
To configure Router2 in Figure 85 on page 457 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 Router1. In this case, the IP address cannot also exist on Router2, but the interface on
which you are configuring the virtual router Backup must have an IP address in the same subnet.
By entering the same IP address as the one associated with this virtual router 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 virtual
router must have a real IP address that is in the same subnet as the address associated with the
virtual router by the Owner. However, the address cannot be the same.
The priority parameter establishes the router’s 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 virtual router if the interface goes down. Refer to
“Track ports and track priority” on
page 458.
