Hi, if the connection between A & B is down than wouldn't B choose to send
all its traffic to C by default because that would be the only route
available.
When you redistribute from OSPF to EIGRP on B the routes will be advertised
to C as External EIGRP routes.
When you redistribute from OSPF to EIGRP on C the routes will be
redistributed to B as External EIGRP routes.
If you change the administrative distance just on C for the External EIGRP
routes to something lower than 110 than C would always choose B as long as
the routes are getting redistributed on B from A. If the link between A and
B goes away than there will be no redistribution hence C will never receive
the routes from B and C will choose the native OSPF routes from A. It will
redistribute these routes to B as External EIGRP routes and now B will
choose C as the next hop.
I hope I have understood your topology and haven't missed anything. Please
correct me if I am wrong. Thanks
