Scenarios
In this lab activity, there are two separate scenarios. In the first scenario, you will learn how to
configure the routing protocol OSPF using the network shown in the Topology Diagram in
Scenario A. The segments of the network have been subnetted using VLSM. OSPF is a classless
routing protocol that can be used to provide subnet mask information in the routing updates. This
will allow VLSM subnet information to be propagated throughout the network.
In the second scenario, you will learn to configure OSPF on a multi-access network. You will also
learn to use the OSPF election process to determine the designated router (DR), backup
designated router (BDR), and DRother states.
