Chapter 11. Hybrid: Enhanced Interior Gateway Routing Protocol (EIGRP)

Lab 20: Integrating RIP Networks: Redistribution, Route Filtering, and Control ”Part I

Practical Scenario

RIP is still one of the most common routing protocols in use today. Although it might not be the dominant protocol on most major internetworks, RIP domains remain sprinkled throughout the internetwork. Integrating these domains and compensating for RIP's lack of support for VLSM can be challenging. This lab gives you practice in integrating RIP and controlling routing updates.

Lab Exercise

Habano Net runs distribution and export information for some of the finest cigar manufactures in the world. Information in Habano Net flows from cigar makers, such as montecristo and romeo_y_julieta to habanos. From here, habanos has connections to worldwide importers, such as churchill_imports. The task will be to integrate the RIP network of the cigar makers to the EIGRP networks of the exporters. Use the following parameters as your design guidelines:

• Use the IP subnet 150.100.100.0/24 for the Frame Relay network between the habanos, montecristo, and romeo_y_julieta routers. Use RIP as the routing protocol. Ensure that montecristo has IP connectivity to romeo_y_julieta.

• Use the IP subnet of 150.100.200.0/30 for the Frame Relay link between the habanos and churchill_imports router. Use EIGRP with 2001 as the autonomous system for the routing protocol.

• Mutually redistribute RIP into EIGRP on the habanos router. Ensure full IP reachability across the entire network.

• Prevent the subnet 150.100.10.0/24 on the habanos router from reaching montecristo and romeo_y_julieta.

• (Optional) Configure the habanos router so that all routes from romeo_y_julieta have an administrative distance of 5.

Lab Objectives

• Configure Habano Net as depicted in Figure 9-7, and configure IP as denoted as well. The LAN topology type is not important in this lab.

• Use Frame Relay as the data-link protocol on the WAN.

• Configure RIP and EIGRP as shown in Figure 9-7. Redistribute between RIP and EIGRP to provide full IP connectivity across the network. Prevent excess routing protocol broadcasts from entering segments that are not running that protocol.

• Prevent the subnet 150.100.10.0/24 on the habanos router from reaching montecristo and romeo_y_julieta.

• (Optional) Adjust the administrative distance of routes originating from romeo_y_julieta.

Equipment Needed

• Five Cisco routers, connected through V.35 back-to-back cable or in a similar fashion. One router will serve as a frame switch and require four serial ports.

• Four LAN segments, provided through hubs or switches.

Physical Layout and Prestaging

• Configure a Frame Relay switch to provide the PVCs as listed in Figure 9-7. See Chapter 1, "The Key Components for Modeling an Internetwork," if you need assistance in configuring a Frame Relay switch. Example 9-12 provides a sample Frame Relay switch configuration.

• Connect the hubs and serial cables to the routers as shown in Figure 9-7.
