Send me your export. I have a similar configuration running just fine.
Hi,
Thanks for your interest!
So, here I attach the export compact for every router:

As you can see I've tried to establish GRE tunnel (now disabled only on ospf) betwenn R2 and R3 (area1) but with no good result, only starting a ping on GRE interface i can reach the remote end (R4).I hope in your help.....
Thanks for your support!
