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.

How to create a horizontal drop down menu in CSS
Written by A.Jesin Wednesday, 2 November 2011 10:11
