Practice Lab 3—The VPN Lab > Section 2: MPLS and OSPF (19 Points)

Section 2: MPLS and OSPF (19 Points)

  • Configure OSPF on your routers, per Figure 3-8, to enable your network to transport MPLS and MP-BGP. All required interfaces (including Loopback 0) should be configured to belong to Area 0. Ensure all OSPF configuration is entered under the interfaces. (3 points)

OSPF is used as the IGP in which to advertise the router loopback addresses, which will of course be used for the MPLS connectivity. The question directs you to configure OSPF directly under the interfaces of the routers. Example 3-4 shows the Loopback interfaces of each router from R1’s perspective advertised as host routes as required for MPLS. If you have configured this correctly, as shown in Example 3-4, you have scored 3 points. Consider using the show ip ospf interface command to verify your configuration.
