Workstations A B IP 161.20.2.2 161.20.1.2 SM 255.255.255.0 255.255.255.0 GW 161.20.2.1 161.20.1.1 Step-by-Step Instructions: 1. Cable and set up the lab as shown. 2. Complete the basic router setup on each router. 3. Configure the interfaces on each router. 4. Configure the routing protocol and advertise/associate/publish the router’s networks. Configure the workstations. You should NOT be able to ping from workstation A to workstation B or vice versa. You should be able to ping from workstation A or B to either loopback. And then try showing the route from …you should see the loopback interface for Phiber (learned via RIP) in the routing table for Optik: optik#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 161.20.0.0/16 is variably subnetted, 4 subnets, 2 masks C 161.20.5.0/30 is directly connected, Loopback0 C 161.20.4.0/30 is directly connected, Serial0/1 C 161.20.1.0/24 is directly connected, Ethernet0/0 R 161.20.3.0/30 [120/1] via 161.20.4.1, 00:00:06, Serial0/1 optik# 5. So let’s fix that little problem here: optik(config)#ip route 161.20.2.0 255.255.255.0 161.20.4.1 What this line says to the router is “to get to the network 161.20.2.0/24 use the interface with the address of 161.20.4.1.” (note: it’s the address on the far side of the serial line…more on that in a bit). Now a request from workstation B to the Ethernet interface has directions on how to get to that address. We have provided them to the router with manual (static) instructions. Our router has summarized our networks because of the addresses we used but, ha-ha!, we are one step ahead of that router because we let it know who’s the boss by slapping a static route in there…take that! 6. Now you should be able to ping from workstation B to the Ethernet interface on Phiber and to workstation A. Now try to ping from workstation A to B. You 231
should not be able to ping. This is because Phiber has no way to direct traffic, even though we did it on Optik. We must add another static route from Phiber to Optik to allow workstation A to be able to ping workstation B. Go ahead and add the route. (Can’t tell you everything step-by-step, otherwise you wouldn’t learn much…ok…if you get stuck you can check the answers.) 7. Static routes are really good for troubleshooting. Later on when you learn about setting up routers with multiple routes to a destination you will learn to use static source router destination router routes to “force” communication over one path in particular to test that specific path. Suppose the route given by the “ “ in the picture above was chosen by the source router to be the “best path” to the destination router. But we wanted to test the capabilities of a “lesser path” (given as “ “) to the destination router. We could force the route with a static route. 8. We can actually specify the interface, rather than using the IP address for setting up a static route (told you we’d come back to it!). So instead of this: optik(config)#ip route 192.168.1.0 255.255.255.0 179.40.6.1 For the same thing we could use this: optik(config)#ip route 192.168.1.0 255.255.255.0 serial0/0 If you forget your options then use your help command: optik(config)#ip route 192.168.1.0 255.255.255.0 ?
