OSPF Application Example
This section will demonstrate how to set up a simple OSPF network. It uses three routers, each with an
area. Each router uses three VLANs. A backbone connects all the routers. This section will demonstrate
how to set it up by explaining the necessary commands for each router.
The following diagram is a simple OSPF network. It will be created by the steps listed on the following
pages:
