On each router, create an OSPF process that puts each interface into area 0.0.0.1. I strongly recommend that you
have one network statement for each interface, but you can experiment with wildcards that put more than one
interface into OSPF. It is your choice whether to advertise the loopback subnets.
You may choose to enable OSPF debugging and watch the activity as OSPF initializes. With increasing numbers of
routers, you will have more and more debug traffic -- you have been warned! Simply record the traffic for later
analysis; it will go by too fast to review on the screen....
