EIGRP - feasible successor problem?

I have 2 wan routers A and B sitting on the same lan running EIGRP to multiple spoke sites. The network is a fully-meshed frame relay network. From Router A I can see all remote sites lans in the routing table and can see alternate routes in the eigrp topology table. I have a problem with remote Site Y though. This site terminates on WAN router A. However from Router B, I cannot see the route for this site Y over the shared ethernet lan from Router A in the topology table. I can see other alternate routes for this site from other remote sites terminated on Router B even though the FD advertised is greater than the FD for site Y.

This site Y is the only site affected, all other sites are okay. CDP works across the lan etc.,

Any ideas?

Re: EIGRP - feasible successor problem?

The basic rule of EIGRP is that the advertised distance(AD) should be less then the fesable distance of that particular route. Just check the advertised route from router A to B.
