company and control access between them. There are three types of routes that are advertised with IGRP: internal, system and external. You will learn more about these in a later lab. Like RIP we must first enable IGRP and then advertise, publish or associate our networks with IGRP (all three things are the same…I have seen it many different ways on tests—hint-hint). IGRP shares characteristics of RIP that we saw in Part 2: it does not pass subnet mask information (geek speak: it truncates at the classful boundary”). Step-By-Step Instructions: 1. Set up and cable the lab as shown. Then set up the basics and interfaces on each router. 2. Add in IGRP as the routing protocol and advertise, publish or associate the networks like this: john(config)#router igrp 38 john(config-router)#network 184.34.0.0 john(config-router)#network 184.35.0.0 draper(config)#router igrp 38 draper(config-router)#network 184.35.0.0 draper(config-router)#network 184.36.0.0 Notice how I picked (out of thin air) to use #38 as my autonomous system number. It really does not matter which one I use just as long as I use the same one on both sides. Notice how I advertised (published/associated) my networks at the classful boundary…a limitation of IGRP. 3. Test by pinging from one workstation to the other. It should work just fine. Do a show ip route. You should see something like this: draper#sh ip route Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2 E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, * - candidate default U - per-user static route, o - ODR Gateway of last resort is not set I 184.34.0.0/16 [100/8576] via 184.35.67.1, 00:00:06, Serial0/1 C 184.35.0.0/16 is directly connected, Serial0/1 C 184.36.0.0/16 is directly connected, Ethernet0/0 draper# 285

Let’s test IGRP’s classful routing capability by changing the serial cable addresses to 192.168.1.1/24 and 192.168.1.2/24. Then try to ping again. Sometimes it might work, but most times it won’t work. Remember we want reliability for our networks too. draper#sh ip route Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2 E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, * - candidate default U - per-user static route, o - ODR Gateway of last resort is not set C 184.35.0.0/16 is directly connected, Serial0/1 C 184.36.0.0/16 is directly connected, Ethernet0/0 draper# C:\WINDOWS\Desktop>ping 184.36.67.3 Pinging 184.36.67.3 with 32 bytes of data: Reply from 184.34.67.1: Destination host unreachable.
