The backup command specifies that this router is a VRRPE 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 VRRPE priority in relation to the other VRRPE routers
in this virtual router. The track-priority parameter specifies the new VRRPE priority that the router
receives for this virtual router if the interface goes down. Refer to
“Track ports and track priority” on
page 458.
The activate command activates the virtual router configuration on this interface. The interface
does not provide backup service for the virtual IP address until you activate the VRRPE
configuration. Alternatively, you can use the enable command. The activate and enable
commands do the same thing.
