Hot Standby Router Protocol

Hot Standby Router Protocol (HSRP) allows you to configure a group of routers as a
single virtual router. The virtual router group is configured with a single virtual IP
address that can be used as the default gateway for host devices on the attached
network.

Configuring HSRP Groups

To configure HSRP, assign the same virtual router address to each router in the
group. Set the highest virtual router priority on the router that will serve as the
master. Enable the preempt feature to allow a router to take over as the master
when it comes on line (if it has a higher priority). To configure the backup routers
with an order of precedence for assuming the role of master, set the appropriate
priority on each of these routers.Then configure an authentication string to ensure
that HSRP messages are only be exchanged between authorized routers. You can
also dynamically adjust the virtual router priority by tracking the availability of any IP
interfaces on the router.
