Hot Standby Routing Protocol

(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").
