Configuring OSPF Stub Areas

Lab 22: EIGRP Route Redistribution, Summarization, and Stub Routing ”Part I

Practical Scenario

As EIGRP networks continue to grow in popularity, it becomes increasingly important to be able to control the query range and integrate it with other routing protocols, such as RIP and OSPF. It is also important to understand the default setting of EIGRP, such as split horizon and autosummarization.

This lab gives you practice in controlling the query range, integrating EIGRP with other routing protocols, and performing summarization.

Lab Exercise

Cisco Training Partners provide custom-tailored Cisco courses around the United States and are in the process of integrating their training facilities over a common network. Your task is to configure an EIGRP network using the following parameters as design guidelines:

• Configure an IP network, as depicted in Figure 11-13, using EIGRP as the routing protocol and 65001 as the Autonomous System ID.

  Figure 11-13. Cisco Training Partners Network

  

• Configure the Frame Relay network as a multipoint network between the wisconsin , georgia , and ohio routers. Configure the Frame Relay network as a point-to-point network between the wisconsin and minnesota routers.

• Ensure full IP reachability with the RIP domain without using static routes or advertising a default route.

• (Optional) Configure the georgia and ohio routers as EIGRP stub routers. The routers should advertise their local LAN networks in EIGRP.

Lab Objectives

• Configure the Cisco Training Partners Network as depicted in Figure 11-13. Configure IP as denoted in the diagram. The LAN topology type is not important in this lab.

• Use Frame Relay data link protocol on the WAN.

• Configure redistribution between RIP and EIGRP.

• Ensure full IP connectivity to all IP interfaces ”that is, be sure that you can ping all Frame Relay and LAN interfaces from the RIP domain. Also ensure that the georgia and ohio routers can ping each others' Frame Relay and LAN interfaces. You cannot configure any static routes or default routes on the network.

• (Optional) Configure the georgia and ohio routers as EIGRP stub routers. You will need Cisco IOS Software Release 12.0(7)T or Cisco IOS Release 12.0(15)S or 12.1 and later, the T and S trains are required.

Equipment Needed

• Six Cisco routers. Four will be connected through V.35 back-to-back cables or in a similar manner to a Frame Relay switch.

• Four LAN segments, provided through hubs or switches. The LAN topology is not significant to this lab.

Physical Layout and Prestaging

• Connect the hubs and serial cables to the routers, as shown in Figure 11-13.

• The stillwater router will run RIP only on network 172.16.0.0. Configure this router at this time. See Chapter 9 if you need assistance on this.

• A Frame Relay switch with three PVCs also is required. Example 11-31 lists the Frame Relay configuration used in this lab.
