Zusammenfassung:	The present invention is directed to a method of resolving protocol addresses using new protocols. Gateways that map ATMARP packets to NHRP packets are place in the network to make translations between the two protocols. Therefore the installed base of networks can be maintained, with added functionality. Techniques for handling those areas where the two protocols do not match directly such as sub-address fields, purge packets and holding time expiration are also disclosed.
