Abstract

In an NHRP (NBMA Next Hop Resolution Protocol) address resolution system for transforming a network layer address to a data link layer address in an NBMA (Non-Broadcast, Multi-Access) network not sharing media, an NHRP
processing section provides a function of resolving an address while an ATMARP (Asynchronous Transfer Mode Address Resolution Protocol) processing section provides a function of resolving an address on the basis of the ATMARP. A holding section is selectively accessed by the NHRP processing section or ATMARP processing section for holding address information registered by the NHRP or address information registered by the ATMARP. When the NHRP processing section receives an NHRP resolution request packet requesting for a resolution of the address of a given ATMARP terminal's address, the processing section sends, if the ATMARP
terminal and a terminal sent the NHRP resolution request packet do not belong to the same subnetwork, a reply representative of the address information of an interface received the request packet.
