Brocade FastIron Ethernet Switch Layer 3 Routing Configuration Guide - Manual (Page 634)

The backup command specifies that this router is a VRRP-E 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-E priority in relation to the other VRRP-E routers
in this virtual router. The track-priority parameter specifies the new VRRP-E priority that the router
receives for this VRID if the interface goes down.
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-E configuration.
Alternatively, you can use the enable command. The activate and enable commands do the same
thing.
