It is a case of IPX split horizon.

two DLCIs to R3 and R5, one IPX network.
pretty clearly R#3, R1, and R5 are members of the same network
and split horizon rules are observed by IPX. So no info from
R3 is advertised to R5. The other routers are on other interfaces
and different networks so split horizon is not an issue with them.
solve this by turning off ipx eigrp split horizon and watch the sap
show up.
