= Small Topology Experimentation =

So far,  we have created an InstaGENI custom image that has `XORP` installed. In order to configure and verify `OSPF` routing, we need to create a network where at least two routers are not directly connected. 

We will test `OSPF` configuration and automation with a four-node topology in this part, and verify that the `OSPF` routing is working properly in this small network.
