Section 48 Lab – OSPF

Topology

Section 48 – Review 6 1

Instructions

Connect two routers together with a serial or crossover cable:

  1. Add IP addresses to the routers and a Loopback interface on Router A and Router B,
    according to the diagram
  2. Ping between Router A and Router B to test the serial line (remember clock rates)
  3. Configure OSPF on both routers
  4. Ensure that you add all the correct wildcard masks
  5. Double-check the WAN wildcard mask and subnet: it ISN’T 172.16.1.0 0.0.0.3!!
  6. Put all networks into an area, but put 192.168.2.0/24 into Area 1 and 10.2.2.0 into Area 2
  7. Check the routing table
  8. Check the router ID for each router
  9. How would you change the router ID for each router?

Solution Hints and Commands

  • Use the router ospf x command to enter OSPF Configuration mode
  • Use the network x.x.x.x y.y.y.y area z command to configure a network in an area
  • Use the show ip route command to view the routing table
  • Use the router-id x.x.x.x command to change the OSPF router ID under the OSPF Process Configuration mode
