Chapter 40: 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.

Virtual Router Redundancy Protocol Commands

To configure VRRP, select an interface on each router in the group that will
participate in the protocol as the master router or a backup router. To select a
specific device as the master router, set the address of this interface as the virtual
router address for the group. Now set the same virtual address and a priority on the
backup routers, and configure an authentication string. You can also enable the
preempt feature which allows a router to take over as the master router when it
comes on line if it has a higher priority than the currently active master router.
