Lab 3 IP Routing

Scenario

You are a senior network administrator who has the job of installing a complex internetwork to connect various branch offices for a large company. You have decided to test various IP routing methods to see which ones work the best. Currently, no routing is configured.

Static Routing

  1. On each router, configure a static route to every other network in the internetwork. See the lab topology drawing for the network numbers.
    1. On the routers use the ip route command.
    2. On the PIX firewall, use the route command.
  2. Test the network by pinging to all other devices. Can you reach every other device? Can you reach the Internet?

Default Routing

  1. In order to reach the Internet, configure a default route that points to a local router that can reach the outside world.
    1. On the routers use the ip route command, followed by 0.0.0.0 0.0.0.0 and the address of the next-hop router.
    2. On the PIX firewall, use the route command, followed by 0.0.0.0 0.0.0.0, the address of the next-hop router, and the number 1. (The PIX makes you enter a metric parameter. We are using 1 to mean one hop.)
  2. Test the network by pinging a server on the Internet such as www.yahoo.com. Can you reach the Internet?

Advanced Distance-Vector Routing (EIGRP)

  1. Remove the static routes (although not the default routes).
    1. On the routers use the no ip route command with the correct parameters.
    2. On the PIX firewall, use the no route command with the correct parameters.
  2. On the routers, configure EIGRP with the following command.
    1. router eigrp 100
    2. network 192.168.x.0 (The "x" should be the number for your subnet. Enter the command for each subnet that your router is directly connected to.)
  3. Unfortunately, the PIX firewall doesn't support EIGRP.
    1. If you are on a PIX, just use default routes.
  4. Check your work (and your cohorts' work) with the following commands.
    1. show ip route
    2. show ip interface
    3. show ip protocol
    4. show ip eigrp neighbors
    5. show ip eigrp topology
  5. Test the network by pinging to all other devices. Can you reach every other device? Can you still reach the Internet?

Submission

Write a short lab report that summarizes your work and any problems you ran into. The lab report should cover:

  1. State of the network before you made any changes
  2. Major changes that you made to the network
  3. Any problems you encountered
  4. Conclusions about the health of the network in its new state

Submit your report

  1. Attach an MS Word-compatible file to the assignment.
  2. Your report should be about 1/2 page long, using a 12-point font and double spacing. It doesn't have to be anything fancy.
