  1. Rene,
    I’m using the Boson Netsim 9.0 simulator and I configured a lab to match what you laid out in this lesson, what has me baffled is how and where do you see the hop count message of 16, when I shutdown the interface on my R3 router (LAN) I turned on debug IP Rip on my R2 router to view the updates being sent from R3. I did see the metric count reach 4 and after that the route was deleted for network, I never saw the hop count reach 16…just curious about this.
    Otherwise a very good explanation and write up RIP protocol
    It could be the

    After the procedure that is described, R3 sends a new hop count to R2 of 2. Now you say since this hop count is higher than that which is already in the routing table of R2, why does R2 replace it? Well, it will replace it because it is an updated piece of information.

    So, the previous entry of metric 1 that was learned fr

The only other situation in which RIP requests are sent is when they are to be used for diagnostic purposes.

    So yes, it is rare to find requests.
