Next Hop Resolution Protocol
Encyclopedia
Next Hop Resolution Protocol (NHRP) is sometimes used to improve the efficiency of routing computer network traffic over Non-Broadcast, Multiple Access (NBMA) Networks
. It is defined in IETF RFC 2332, and further described in RFC 2333.
"[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."
Nonbroadcast Multiple Access Network
A non-broadcast multiple access network is a computer network to which multiple hosts are attached, but data is transmitted only directly from one computer to another single host over a virtual circuit or across a switched fabric. NBMA networks do not support multicast or broadcast traffic...
. It is defined in IETF RFC 2332, and further described in RFC 2333.
Description
