Last year while I was preparing for my R&S Lab, I felt I was not well prepared for complex redistribution scenarios. I took a look at Vol-1 workbooks outline from IP Expert and Internetwork Expert but none of them seems to cover Redistribution as part of Technology labs. So I thought to create some ugly redistribution lab my self.
So let me quickly share the physical & logical topology here with you guys along with initials.
Requirement is simple - to perform mutual redistribution at all redistribution points without creating a routing loop.

I would like to mention here that I am not looking for optimal routing here after redistribution, R4 has 3 routing protocols running, so make sure all three have mutual redistribution.
All you need to know about redistribution is right here
