Router Redundancy Commands
Router redundancy protocols use a virtual IP address to support a primary
router and multiple backup routers. The backup routers can be configured
to take over the workload if the master router fails, or can also be
configured to share the traffic load. The primary goal of router redundancy
is to allow a host device which has been configured with a fixed gateway to
maintain network connectivity in case the primary gateway goes down.
