Frame relay is a WAN technology that uses packet switching methodology for communication. A frame relay switch is required for configuring a frame relay network. The previous article on Configuring Frame Relay on Cisco Packet Tracer explains it on a simulator, in this article I’ll show how a Cisco router can be used as a frame relay switch. The same hub and spoke topology is used, only the Frame Relay switch router configuration is explained here refer the previous article for the Hub router and spoke routers configuration instructions.Continue Reading…

This article will explain frame relay configuration in Cisco Packet Tracer. Frame relay is a WAN technology. Read the Wikipedia article to learn more about Frame Relay. You can also try this on live routers and other network simulators, but the frame relay switch configuration varies. The setup here will use the hub and spoke configuration, Router0 is the hub, Router1 and Router2 are the spokes. Point-to-Point subinterfaces are created and PVCs (Permanent Virtual Circuits) are established between Router0 and Router1 and Router0 and Router2. So the Spoke routers communicate via Router0.Continue Reading…
