Foundry Switch and Router Installation and Configuration Guide
Router1(config-if-1/6)# ip vrrp vrid 1
Router1(config-if-1/6-vrid-1)# owner track-priority 20
Router1(config-if-1/6-vrid-1)# track-port ethernet 2/4
Router1(config-if-1/6-vrid-1)# ip-address 192.53.5.1
Router1(config-if-1/6-vrid-1)# activate
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 VRID.
Because this router owns the IP address, this router is the default Master router and its VRRP priority is thus 255.
Configuring Router2 Using the CLI
To configure Router2 in Figure 21.2 on page 21-3 after enabling VRRP, enter the following commands:
Router2(config)# router vrrp
Router2(config)# inter e 1/5
Router2(config-if-1/5)# ip address 192.53.5.3
Router2(config-if-1/5)# ip vrrp vrid 1
Router2(config-if-1/5-vrid-1)# backup priority 100 track-priority 19
Router2(config-if-1/5-vrid-1)# track-port ethernet 3/2
Router2(config-if-1/5-vrid-1)# ip-address 192.53.5.1
Router2(config-if-1/5-vrid-1)# activate
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 VRID
Backup must have an IP address in the same sub-net. 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 sub-net as the address associated with the VRID 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 router(s) 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. See "Track Ports and Track Priority" on page 21-5.
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.

USING THE WEB MANAGEMENT INTERFACE
Use the following procedures to create a virtual router using the Web management interface.
