Next Hop Resolution Protocol
The Next Hop Resolution Protocol (NHRP) is defined in RFC- 2332 (April 1998)
The NBMA Next Hop Resolution Protocol(NHRP) can be used by a source station (host or router) connected to a Non-Broadcast, Multi-Access (NBMA) subnetwork to determine the internetworking layer address and NBMA subnetwork addresses of the "NBMA next hop" towards a destination station
NHRP is used to find a short-cut between hosts on two ELANs on the same ATM network
