In this video, we show how to configure a basic frame-relay network with one hub and two spokes. The configuration is pretty straightforward and simple, and nearly identical on all three routers. As such, a lot of the video is repetitive. It does, however, go from blank configurations to a fully-configured frame-relay hub-and-spoke network with full connectivity.

Here’s the topology:

As you can see, we’re using the 172.16.123.0/24 network and physical interfaces (no sub-interfaces). The DLCI numbers are illustrated in the diagram.

Here’s the video:

Part 2 uses a similar topology but in a full-mesh configuration with point-to-point connections (and sub-interfaces, of course). Part 3 will use a combination of physical interfaces and sub-interfaces to show how to set up both simultaneously. In Part 4, we’ll be configuring OSPF over the network we set up in Part 3, to show the differences in how OSPF works over various types of networks.
