what if I have to use the physical interface for my frame connection? Do
I just create the sub-int and put all the other pvc's into it?

This is, actually, not an "error" by itself.

Your backbone router send EIGRP multicast packets on multiple PVCs.
Since all those PVCs are "linked" to physical interface by default,
and you have IP enabled on the same interface, multicasts are delivered
to EIGRP routing process.

But because they have "incompatibe" source ip addresses (different ip
subnets)
EIGRP complains on "neighbor not on common subnet". Neighbor with
correct IP will work okay with your router, though :)

To get rid of that message completely, create a subinterface, and link a
single
DLCI to it.

        This is an ADJ to BB1 and on BB1 the eigrp network statement is

        Is this an IOS issue? PVCs are active but they are unused.
        Any suggestions would be appreciated,
