what is nhrp cisco
The purpose of this module is to describe how to configure the Next Hop Resolution Protocol (NHRP) for use in a nonbroadcast multiaccess (NBMA) network. NHRP is an Address Resolution Protocol (ARP)-like protocol that dynamically maps nonbroadcast multiaccess (NBMA) network.hen BGP discovers a BGP next hop and enters this BGP route into the routing table, an NHRP request is sent to the BGP next hop. When an NHRP reply is received, a subsequent route is put in the NHRP cache that directly corresponds to the BGP next hop.
