Day 5

Homework:  TCP/IP, Doyle, pp. 191-324

Finish any of the Day 4 assignments that you did not complete in the routers:

1. Take a pod from the Static routing exercises that you will do in lab. Write out in notepad and actually try out in the routers some sample Default routing configurations.

2. Intentionally create a routing loop for the 90.0.0.0 network between podxr2 and podxr1 when you are running a traceroute from pxr4

3. Create an outage where a traceroute from podxr4 to podxr1 fails because podxr1 does not have a route back from podxr1 to podxr2 for the network that podxr4 is on.

4.  Do a traceroute to the 90.0.0.0 network from podxr4. Then shut down the s1 interface on podxr2 and run the traceroute again. How is the traceroute similiar or different? Is RIP able to dynamically able to route around the "outage"?

In Class:

1.  Look at the sample RIP configurations for pods 1 and 2.  After you erase your router, turn "debug ip rip" on.  Create and configure RIP configurations for the other pods.

2.  Work with your other "pod mates" to create /30 subnets.  (You may use the networks already on the diagram, or you may be more creative).   Reconfigure your pods using these different subnets.

3.  Work with your other "pod mates" to create /27 subnets.  (You may use the networks already on the diagram, or you may be more creative).   Reconfigure your pods using these different subnets and the IGRP routing protocol.  (If you have forgotten how to configure with igrp, then check the sample igrp configs link off the home page).  After you erase your router and before you configure it, turn "debug ip igrp events" and "debug ip igrp transactions"  on.

4.  Work with your other "pod mates" and have some of you do RIP routing and some of you IGRP.  Does it work?  Do you need to use the "redistribute" command?  Do the routes from your pod get passed to other pods?

5.  Work with your other "pod mates" and come up with a routing design that incorporates Static, Default, RIP, and/or IGRP routing.  (There is possibly more than one right answer.)
