Configuring VRRP

The Virtual Router Redundancy Protocol (VRRP) is designed to eliminate the 6400-S as a single point of failure in a network configuration. Two 6400-S devices can be configured to perform as a redundant pair. One 6400-S is the Master, the other is the Backup. If the Master fails because of a network or hardware failure, the Backup takes over for the Master.

To configure VRRP:

1.In the navigation bar, select System.
