Question on Task 4.8
I tackled this task by applying tag to routes being redistributed into OSPF (routemap RIP2OSPF) on R4, and I filtered out the tagged routes on R5 as I redistributed OSPF2RIP and I did the same on R5, tagged routes redistributed into OSPF on R5 and filtered it on R4 as I redistribute OSPF2RIP. I thought that this was the classic loop prevention mechanism but the issue I ran into was that R1 did not receive the OSPF routes redistriuted into RIP on R4 and consequently I did not enjoy full reachability.
Can some please point out to me the fundamental flaw with my approach. I am desperate to know.
