Abstract
A method is implemented by which a Logical IP subnetwork attached (LIS) Next Hop Resolution Protocol (NHRP) client or an Emulated LAN (ELAN) subnetwork attached NHRP client in an Asynchronous Transfer Mode (ATM) network can send data to a destination LAN Emulation Client (LEC) on a different ISO layer-3 subnetwork via a data-direct Virtual Channel Connection. The method enables such a IP subnetwork attached NHRP clients to obtain the ATM address corresponding to the destination station by using the vendor-private extension within an NHRP packet. The NHRP client uses the ATM address to build a data-direct VCC over which it unicasts data bound for the destination station. The NHRP client appears to the destination LEC as any other LEC on its ELAN would appear.
