Explain Next Hop Resolution Protocol (nhrp)?

1.	Explain Next Hop Resolution Protocol (nhrp)?
Answer» It is a Layer 2 PROTOCOL which is used to map a tunnel IP address to an NBMA address. It functions similar to ARP. Hub maintains NHRP database of the PUBLIC addresses for each spoke. When the spoke boots up, it registers its real address to the hub and QUERIES the NHRP database for real addresses of other spokes so that they can build direct TUNNELS.
