RIP Challenge 1 - Solve The Puzzle

So here we are with another Challenge 1 for this week. I am sure that coming up with 2 exiting challenges is not a bad idea either. Anyways...Let's talk about RIP challenge as most of the networks guys (specially experienced ones) gonna say...."ehhh.....that should be simple" coz it's RIP. RIP...hmmm....RIP is very simple and straight forward kind of stuff...at least that's what most of people think.


Anyways let's me show the RIP diagram with all details and the requirement to full fill :-)

Requirements: My Favorite Part :-) 
1. The RIP Updates from R1 over network 12.12.12.0/24 
    should not be send as "Multicast" or "Broadcast" packets. 


2. Establish Full Connectivity/reachability among 
    loopback interfaces of all three routers.


Restrictions:
1. "neighbor" command shouldn't be used anywhere.
2.  Redistribution is not allowed anywhere.
3.  PBR, Static Routing, Default Routing, Tunnels are not allowed.


Best Of Luck...
