In “Configuring Frame-Relay, Part 1″, I demonstrated how to configure a basic frame-relay hub and spoke network.

In Part 2, we have the same three routers with the same physical topology, but we’ll be using point-to-point connections between each of the routers.

Here’s the topology…

…and the walkthrough…

In Part 3, we’ll add another router, R4, to the topology and use a combination of the physical interface and point-to-point subinterface on R1 to demonstrate how to use both simultaneously. We’ll follow that up in Part 4 by adding OSPF to the whole network to show the differences over various types of networks.
