Basic Objectives: 1. Configure and cable the Serial and Ethernet interfaces as indicated in the above diagram. 2. Configure IP addresses between the routers using the following 192.168.YY.x/24 scheme: Router 13=192.168.13.x Router 56=192.168.56.x Router 23=192.168.23.x Router 78=192.168.78.x Router 34=192.168.34.x Router 79=192.168.79.x Router 45=192.168.45.x Router 910=192.168.109.x Router 47=192.168.47.x Router 911=192.168.119.x 3. Configure a loopback interface on each router. The interface should have an address using the following scheme: Y.Y.Y.Y/24. For example, Router 4's loopback should be 4.4.4.4/24. OSPF Objectives: 4. Configure OSPF on all routers. Use whatever process ID you wish. 5. Manually set the OSPF router-ID on your router to your loopback IP. 6. Place each interface on your router into the Area specified by the diagram. Place loopback interfaces in whatever area is easiest. USPF Ubjectives: 7. Configure OSPF md5 authentication throughout your OSPF domain. Use a key of "CISCO" between all neighbors. 8. Area 123 and Area 8 should not accept Type 3, 4, or 5 LSAs. Area 56 and Area 1011 should not accept Type 4 or 5 LSAs. However, all areas should accept Type 7 LSA's. OSPF Objectives: 9. Ensure that all networks are reachable. 10.On each router, create a loopback interface with the following address 66.XX.1.1/16, where XX is your router number. 11.Create static routes on each router to the following networks, and set a next hop of 66.XX.1.2: 77.XX.0.0/24, 77.XX.1.0/24, 77.XX.2.0/24, 77.XX.3.0/24 USP' UDJectives: 12. Redistribute these static routes into the OSPF process. Check your routing tables to ensure these routes have propagated. 13.Configure OSPF to summarize these redistributed routes into a single route. However, you still want the 77 .XX.1.0 network to be advertised individually
