Connect gi2/7 on cat6500 to another box and try setup ospf with bfd in some another ospf process. You can do it for me3600 too.

Thanks to Andrew Koch, I've finally managed to bring the session up.

On C6500_1 there was an overlapping subnet configured on an interface 
that has been shut down months ago.t

Gi2/7        1     0          10    P2P   1/1
Gi3/11       1     0          10    DOWN  0/0

That was enough to break the BFD stack.

Thank you for your help.
