Narbik’s Soup-to-Nuts Workbook RIPv2 Lab 6

"Lab 6 - Advanced RIPv2 configuration" was a very interesting lab. I actually got stuck on Task 1 that required that I configure RIPv2 on the ethernet segment. I thought it was funny that it stated if I see R1's loopback on R2 then the configuration is successful. I thought to myself, that shouldnt take more than a minute. Well I was wrong. I didn't pay attention the the ip addressing and it WAS NOT THE SAME! After clearing ip routing tables 5 times I said to myself: "Man this must be something tricky". Well looked up in the answers and guess what? There is a whole paragraph on it in the docCD.

RIP and IGRP are the only two routing protocols that validate the source IP address of incoming updates DOH!

Disabling the Validation of Source IP Addresses

By default, the software validates the source IP address of incoming RIP routing updates. If that source address is not valid, the software discards the routing update. You might want to disable this feature if you have a router that is "off network" and you want to receive its updates. However, disabling this feature is not recommended under normal circumstances.

To disable the default function that validates the source IP addresses of incoming routing updates, use the following command in router configuration mode: 

So even though it is not recommended, for this task I had to use disable this feature and baam all the routes show up in the routing table.

Task 2 requires that we filter prefixes based on the prefix-length. Using a prefix-list with a distribute-list will take care of this. Make sure to use the "gateway" option so that it only allows updates from one router.

Another main command to remember is "ip rip triggered" under the interface so that RIP will suppress regular updates unless there is a topology change.

Task 5 will use ip summary-address rip command under the interface to advertise summary address only. I would recommend going over the RIP chapter in DocCD because all of this is listed there.

This ends the RIPv2 labs and I need to start EIGRP. I am WAY BEHIND schedule and was hoping to finish this workbook by tomorrow. I am not sure if that's going to happen. Bootcamp starts next monday and according to Narbik, I need to relax for a few days before showing up to his class Let's see how much I can squeeze in tomorrow and then I will update my schedule with the new deadline

Have a good night!
