HSRP (Hot Standby Router Protocol) Related Entries Web Links New/Updated Information Note: Many topics at this site are reduced versions of the text in "The Encyclopedia of Networking and Telecommunications." Search results will not be as extensive as a search of the book's CD-ROM. HSRP is a Cisco protocol that switches to a backup router if a main router fails. The protocol provides automatic router backup (fault tolerance). HSRP is compatible with IP, Novell's Internetwork Packet Exchange (IPX), AppleTalk, and Banyan VINES, and it is compatible with DECnet and Xerox Network Systems (XNS) in certain configurations. In a WAN configuration, HSRP can provide a way to forward packets on an alternate link should a primary link fail. HSRP is defined in RFC 2281 (Cisco Hot Standby Router Protocol, March 1998) and at the Cisco Web site (see address following). Copyright (c) 2001 Tom Sheldon and Big Sur Multimedia.
