NOTE: To enable the new master router to send PPPoE Active Discovery
Termination (PADT) packets to the clients and create new sessions for the
PPPoE subscribers, you must create a dummy IP interface for each S-VLAN
that is part of the ICR partition.
The following example shows how to configure a backup ICR partition on an E320 router.
Configure the interface on which the ICR partition resides and then create a new VRRP
instance that manages the backup ICR partition. The value you assign to the priority
keyword determines the state of the ICR partition. In the case of a backup ICR partition,
specify a value lower than the priority of the master ICR partition.
Configure the interface on which the ICR partition resides.
