Objective: configure Routers 1, 2, and 4 with IP addresses, and then add static routes for all routers.
Lab Equipment: Router 1, Router 2, and Router 4 from the eRouters menu
• Set the host name, and bring up the interfaces.
• Ping the directly connected interfaces.
• configure static routes for the topology.
• Verify that you can ping all routers.

1. configure Routers 1, 2, and 4 to the specifications outlined in the table and diagram below.

2. On each router, verify that you can ping the directly connected neighbors.




3. Now you need to establish static routes on each router to any location that is not directly connected. Router1 is directly connected to both Router2 and Router4, so it will not need any static routes.On Router4, enter global configuration mode, and think about what the static route command should be. You know that you currently cannot reach Router2 because it is not directly connected. Off of Router4’s serial interface is network, which is
connected to Router1. Router1 is also connected to network, which you would also like to access. In this case, you will need a static route for network On Router4, what command should you use to establish a static route to network

Router4#conf term
Router4(config)#ip route

You established a route to network Now, whenever a packet of information leaves Router4 destined for network, it will first be sent to IP address on Router1.

4. Now, try to ping Router1’s serial 0 interface, Router1’s Ethernet 0 interface, and Router2’s Ethernet 0 interface.



Consider why the ping to (Router2’s Ethernet 0 interface) was unsuccessful. A packet leaves Router4’s serial 0 interface destined for Because the destination address is on the network and the static route on Router4 stipulates that traffic destined for that network should first be sent to, the packet will travel to When the packet reaches Router1, the router sends the packet out the interface that is directly connected to the network. Router2 picks up that packet on its Ethernet 0 interface and attempts to send a response packet to confirm receipt.
Router2 examines the source IP address of the received packet, which is’s serial 0 interface). Router2 does not have a route to network, so it drops the packet. This is why the ping was not successful.

5. Just to make sure the static route on Router4 worked, view the routing table to see if the static route has been added there.
Router4#show ip route

6. To enable Router4 to ping, connect to Router2 and configure a static route back to Router4’s network. Type the command that will set a static route on Router2 for the network
Router2#config term
Router2(config)#ip route

Consequently, any data sent to network will go to first.

7. Connect to Router4 again, and make sure you can ping Router1’s serial 0 interface,Router1’s Ethernet 0 interface, and Router2’s Ethernet 0 interface.



8. Examine the routing table on Router2.
Router2#show 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
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
Gateway of last resort is not set
C is directly connected,
S [1/0] via

In the S [1/0] via line of output, the S denotes the static route.
Next, the destination network and its subnet information ( are displayed.
The [1/0] represents the administrative distance, which is 1 by default, and the metric(hop count in this case), which is 0. The word via signals the next hop address the packet should be sent to, which in this case is
