Hot Standby Router Protocol Commands
To configure HSRP, add the interface for each router that will participate in the virtual
router group, set the priorities, and configure an authentication string. The HSRP
protocol will automatically select the master and standby router based on the priority
settings. You can also enable the preempt feature which allows a router to take over
as the master router when it comes on line. HSRP also allows you to specify a set of
interfaces that dynamically change the router priority based on their availability.
