Task 4.10 -- RIPv2 filtering with Prefix Lists

Hi,

 

I don't quite understand the solution for second bullet. This is what the Solution Guide says:

* on R5, under rip process: distribute-list prefix PERMIT_ALL gateway NOT_FROM_R4 in

* the way I had attempted to solve this was by correctly creating NOT_FROM_R4 prefix list but obviously that didn't achieve the purpose by itself. What is the functionality of the "gateway" in this distribute list.

* why doesn't just applying the distribute list in the following manner work? : Rack1R5(config-router)# distribute-list prefix NOT_FROM_R4 in

thanks

    With just the single prefix-list how can you control who's you're
    receiving it from?  The "gateway" portion matches the update source of
    the prefix as well as the route itself.
