Yes, Recursive Routing will occur because :
Router R5 PREFER Tunnel interface (area 0) to reach R1 Interface(area1)
(destination) but Tunnel interface is build based on these
Source/Destination => Recursive Occur. I hope you understand what I mean.
(IE explained this situation in details Solution Guide but I don't remember
which page.)
Thanks
