GRE Route Recursion
I think the key with this issue is to ensure that you don’t learn a preferred path to get to networks through your tunnel that includes the path to get to the tunnel. So, R1 thinks that the path to get the tunnel destination is through the tunnel itself. I can think of four methods that I have used to prevent this:
1) Distribute-list 2) Offset-list 3) distance related commands 4) Route-maps
