Configuring Point-to-Multipoint OSPF Over Frame Relay
Routers Used : 3640 w/ NM-4T IOS : c3640-jk9s-mz.124-16a Objective In this lab, configure OSPF as a point-to-multipoint network type so that it operates efficiently over a hub-and-spoke Frame Relay topology. Scenario International Travel Agency has just connected two regional headquarters to Asterix using Frame Relay in a hub-and-spoke topology. OSPF routing is to be configured over this type of network, which is known for introducing complications into OSPF adjacency relationships. To avoid these complications, manually override the Non-Broadcast Multi-Access (NBMA) OSPF network type and configure OSPF to run as a point-to-multipoint network. In this environment, no DR or BDR is elected. Step 1 Cable the network according to the diagram. Configure the FastEthernet or Loopback interface for each router as shown, but leave the serial interfaces and OSPF routing unconfigured for now. Until Frame Relay is configured, ping is not useful for testing connectivity. Configure por...
