Objectives

Part 1: Configure OSPFv2 Routing

Part 2: Verify the Configurations

Background

In this activity, the IP addressing is already configured. You are responsible for configuring the three router topology with basic single area OSPFv2 and then verifying connectivity between end devices.

Note: The topology is the same one used in the chapter examples. In addition, the student practiced the configuration of this topology in the Syntax Checker activities. Therefore, the student should be able to complete this activity with minimal assistance.

Instructions

Part 1:Configure OSPFv2 Routing

Step 1:Configure OSPF on the R1, R2 and R3.

Use the following requirements to configure OSPF routing on all three routers:

  • Process ID 10
  • Router ID for each router: R1 = 1.1.1.1; R2 = 2.2.2.2; R3 = 3.3.3.3
  • Network address for each interface
  • LAN interface set to passive (do not use the default keyword)

Step 2:Verify OSPF routing is operational.

On each router, the routing table should now have a route to every network in the topology.

Step 3:Verify the Configurations

Each PC should be able to ping the other two PCs. If not, check your configurations.
