Next Hop Resolution Protocol (NHRP) is sometimes used to improve the efficiency of routing computer network traffic over Non-Broadcast, Multiple Access (NBMA) Networks.[1] It is defined in IETF RFC 2332,[2] and further described in RFC 2333.[3] It can be used by a sender to determine a route with the fewest number of hops to a receiver.[4] The protocol differs from ARP-type protocols in that it allows routing optimization across multiple IP subnets.[5]

Description

From RFC 2332: "[NHRP] allows a source station (a host or router), wishing to communicate over [an NBMA] subnetwork, to determine the internetworking layer addresses and NBMA addresses of suitable 'NBMA next hops' toward a destination station."
