Configuring Wide Area Networking Using SMDS

This chapter describes how to configure your bridge/router to establish serial line connectivity through Switched Multimegabit Data Service (SMDS). It also describes how this wide area protocol works and it provides guidelines for operating, managing, and troubleshooting the protocol.

The wide area bridge/router supports bridging and routing over SMDS. SMDS allows your bridge/router to bridge or route over SMDS connectionless data service to other bridge/routers on the same wide area network.

SMDS, X.25, Asynchronous Transfer Mode (ATM), and Frame Relay allow only one path to be assigned to a port. Only one of these wide area protocols can run over a single path or serial line. For example, in Figure 349, SMDS is being run over port 3 on bridge/router 1, while X.25 is being run over port 4.
