OSPF Over Frame-Relay: Point-to-Multipoint

Scenario:

As the senior network engineer for a Dutch fishing company you are responsible for connecting all the different branch offices to the main network. The WAN technology you are using is Frame Relay, and you need to run OSPF over this WAN connection.

Goal:

• The frame-relay switch has been preconfigured for you, as you can see in the topology picture the following PVC's has been configured:
  
  Router Barracuda to Salmon:
  Barracuda: DLCI 102
  Salmon: DLCI 201
  
  Router Barracuda to Herring:
  Barracuda: DLCI 103
  Salmon: DLCI 301
  
  
• Router Barracuda is the "Hub" router and the other 2 routers are the "Spoke" routers.
• Do not change any configuration on the Frame-Relay switch.
• Configure the following IP addresses:
  Router Barracuda:
  S0/0: 192.168.123.1 /24
  L0: 1.1.1.1 /24
  
  Router Salmon:
  S0/0: 192.168.123.2 /24
  L0: 2.2.2.2 /24
  
  Router Herring:
  S0/0: 192.168.123.3 /24
  L0: 3.3.3.3 /24
• Configure all serial interfaces for encapsulation Frame-Relay.
• Disable Frame-relay inverse arp on all serial interfaces.
• Configure the correct frame-relay map statements on all routers and make sure you can ping every IP address.
• Configure the OSPF network type to "point-to-multipoint" on all serial interfaces.
• Configure OSPF on all 3 routers, make sure you have full connectivity. All IP addresses including the loopbacks should be reachable.
• You are not allowed to use the "neighbor" command in the OSPF configuration.
