Next Hop Resolution Protocol (NHRP): A Comprehensive Guide

  Next Hop Resolution Protocol (NHRP): A Comprehensive Guide In networking, protocols play a vital role in ensuring efficient communication and connectivity between devices.  One such protocol is the Next Hop Resolution Protocol (NHRP) , which facilitates dynamic routing in non-broadcast multiple access (NBMA) networks.  This article explores the fundamentals, functionality, and applications of NHRP, providing a clear understanding of its importance in modern network architectures. What is NHRP? The Next Hop Resolution Protocol (NHRP) is a networking protocol defined by the Internet Engineering Task Force (IETF) in RFC 2332 . It is primarily designed for NBMA networks, such as Frame Relay, Asynchronous Transfer Mode (ATM), and Multiprotocol Label Switching (MPLS). NHRP operates at the network layer and is responsible for discovering the next hop's IP address and mapping it to its corresponding NBMA address. By resolving the next hop dynamically, NHRP optimizes data tr...
