Scenarios
In this lab activity, there are two separate scenarios. In the first scenario, you will learn how to config-
ure 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 how to configure OSPF on a multiaccess network. You will also
learn how to use the OSPF election process to determine the designated router (DR), backup designat-
ed router (BDR), and DRother states.
Scenario A: Basic OSPF Configuration
Figure 11-11 shows the topology diagram for this scenario, and Table 11-2 provides the interface, IP
address, subnet mask, and default gateway (where applicable) information for the routers and PCs
shown in Figure 11-11.
