Case Study 2: Frame Relay and OSPF Solution

Transcription

1 Case Study 2: Frame Relay and OSPF Solution Objective In this case study, you troubleshoot a complex scenario involving Frame Relay and Open Shortest Path First (OSPF). Figure 2-1 shows the topology for this case study. Figure 2-1 Topology for the Case Study Lo 0 Lo / /24 Lo /24 ISP1A DCE S0/ /30 RIP Lo /24 Lo /24 S0/ /30 DTE SanJose1 S0/ /24 DLCI 102 DLCI 103 Adtran 1/1 Frame Relay OSPF Area 0 Adtran 1/2 DLCI 201 DLCI 301 S0/ /24 Westasman London Fa0/ /24 OSPF Area 1 Stub Adtran Atlas 500 Adtran 2/1 S /24 Baypointe London Fa0/ /24 OSPF Area 2 Stub Scenario The International Travel Agency (ITA) hired you as a networking consultant to help troubleshoot and fix a problem it is having part of its network. A few days ago, ITA decided to readdress and reconfigure the connections among SanJose1, Westasman, and Baypointe. Routing Information Protocol (RIP) and static routes were being used for routing traffic in Figure 2-1. Then one of the network administrators decided to use the more efficient routing protocol, OSPF. ITA reconfigured this part of its network to use OSPF as its routing protocol and added some other features that are described next. Unfortunately, this action has broken ITA s network. The company has decided that it does not want to go back to using RIP and static routes. Instead, ITA wants to hire you to correct its problems this new configuration. You need to use the following specifications.

2 2 Cisco Networking Academy Program CCNP 4: Network Troubleshooting Lab Companion Using Figure 2-1, you must configure the network the following specifications: All routers should be able to reach (ping) all interfaces on the other routers. All interfaces on all routers should be able to reach the Internet. You can test this by pinging , , and from all routers. Westasman should be able to ping these IP addresses using its loopback interface of SanJose1 should be the default gateway (the gateway of last resort) for Westasman and Baypointe. SanJose1 and ISP1A will not be running dynamic routing protocols. ISP1A has a static route for the /16 network, pointing toward SanJose1. OSPF is the routing protocol between SanJose1, Westasman, and Baypointe. SanJose1, Westasman, and Baypointe are connected via point-to-multipoint Frame Relay, SanJose1 acting as the hub router and Westasman and Baypointe as the spoke routers. The OSPF routers are using message digest (MD5) authentication the password itsasecret. Loopback 0 interfaces are being used for OSPF Router IDs on all OSPF routers. Baypointe s /24 network is a stub network in OSPF area 2. Westasman s /24 network is a stub network in OSPF area 1. Westasman is also routing RIP on a separate interface. These networks include /24 and /24 and need to be redistributed into OSPF so that the other routers can route to these subnets. Baypointe and SanJose 1 can test this by pinging and (For purposes of this lab, these networks are configured as loopback interfaces on Westasman.) Notes Your router interfaces might differ depending on the model number. For example, if Baypointe is a 2600 series router instead of a 1700 series, the interfaces would be Serial 0/0.1 and FastEthernet 0/0. You do not need to connect FastEthernet interfaces to switches or hubs. Broken running-configs contain no keepalive statements, which keep the port in an up state. You do not need to make changes to the ISP1A router. Connectivity and routing problems might be because of multiple issues on multiple routers. In other words, making a correct change on a router might solve one problem, but routing might still not be taking place because of other problems this or other routers. Be sure you have a reason for making every change. Making random or incorrect changes might introduce new problems to the scenario. Even though you might see the problem immediately using show running-config, use other show and debug commands to view these outputs. Some of these commands might include the following: ➐ ➐ ➐ ➐ ➐ ➐ show ip ospf show ip ospf [neighbor interface database] debug ip ospf [events adj packet] debug ip rip show ip route show protocols

3 Cisco Networking Academy Program CCNP 4: Network Troubleshooting Lab Companion Step 1 Cable the lab as shown in Figure 2-1. Load the LabA-16SanJose1BrokenConfig.txt, LabA-16WestasmanBrokenConfig.txt, and LabA-16BaypointeBrokenConfig.txt configuration files. Load the working config for the ISP1A router: LabA-16ISP1AWorkingConfig.txt. (See detailed instructions in the introduction to Appendix A, Supplemental Troubleshooting Labs and Case Studies, found in CCNP 4: Network Troubleshooting Lab Companion.) Step 2 Verify the running configuration of all the routers the Broken config files. For example, if you used a 1700 router instead of a 2600 router, be sure that your router has the same configuration information for FastEthernet 0 as the 2600 listing has for FastEthernet 0/0. Make any necessary adjustments to your current running configs. Step 3 Troubleshoot and fix any problems. List the problem, the commands you used to troubleshoot the problem, and the command you used to fix it. Broken Configs NOTE: When you use the broken configs, first erase the startup-config and reload the router, and then enter global configuration mode (Router(config)#) before pasting these configs into the appropriate router. ISP1A Router Configuration This is a good config. No changes to this router need to be made.
