Hot Standby Routing Protocol

from The Free On-line Dictionary of Computing (8 July 2008)

Hot Standby Routing Protocol
HSRP

   <protocol> (HSRP) A {CISCO} standard, defined in {RFC 2281},
   that calls for a {mirrored router} in {passive mode} to send
   {hello packets}, wait for a {lead router} to die and, without
   dropping a {packet}, take over from that router.

   Note: "standby", not "swappable" (and certainly not
   "swapable").
