HSRP

HSRP stands for Hot Standby Routing Protocol, HSRP is Cisco proprietary protocol. HSRP is a routing protocol that provides backup to a router in the event of failure. Using HSRP, several routers are connected to the same segment of a fast Ethernet, token-ring network and work together to present the appearance of a single virtual router on the LAN network. The routers share the same MAC and IP addresses; therefore in the event of failure of one router, the hosts on the LAN are able to continue forwarding packets to a consistent IP and MAC address.
