ABSTRACT
LANs, connecting Token Ring LANs encompasses a separate set of issues. Unlike Ethernet, bridging predominates in Token Ring environments. Source routing, which is used in Token Ring, is a more sophisticated form of internetworking than transparent bridging, and this has staved off the onslaught of routing. Yet, as MIS builds increasingly complex networks, routing will become a more critical element in Token Ring internetworks. When internetworking Token Rings, you have three options: source-routing bridging, routing, and source routing transparent.
