You can add as #5 Proper area placement of interfaces (if you have the
choice on OSPF)

Subject: Re: 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
