Hot Standby Router Protocol (HSRP)
Hot Standby Router Protocol (HSRP) provides high network availability and transparent network topology changes. HSRP creates a hot standby router group with a lead router, that services all packets sent to the hot standby address. The lead router is monitored by other routers in the group, and if it fails, one of the standby routers inherits both the lead position and the hot standby address.
