OSPF and EIGRP interaction troubles

hi there, well, I have basically the following:

A B

-------------------------- Net 1 { | } | { | } |

-------------------------- Net 2 C D

A, B, C, D are cisco routers, mix of != type.

{ } represent a slow backup link,

| | represent a fast link

A, B are configured using EIGRP C, D are configured using OSPF (differents clients) sometimes the fast link drop, and the backup take place. OK when the fast link come back, the C router get blindly routing throught A to reatch Net1, I have to manually set it back to the default D-B link.(shut down of A side interface) I don't know why routes doesn't come back to normal after link restore. I think this is because of bad interaction of protocols. or may be a too selective neighborhood ? May I have your points of view.

thanks for your time.
