The backup command species 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 conguring Switch 1. In this case, the IP address cannot also exist
on Switch 2, but the interface on which you are conguring 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 conguring the Backup to back up the address, but you
are not duplicating the address.
NOTE
When you congure a Backup router, the router interface on which you are conguring 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 species the new VRRP-E priority that the router receives for this VRID if the interface goes down.
The activate command activates the VRID conguration on this interface. The interface does not provide backup service for the virtual IP
address until you activate the VRRP-E conguration. Alternatively, you can use the enable command. The activate and enable
commands do the same thing.
