Even if it is "switched from spoke-to-spoke", at Layer 1 the spokes connect via the hub. And to do anything with the traffic, Layer 2 must be consulted -- which gives us Priscilla's DLCI switching table. And, unless the traffic is unidirectional, you will need DLCIs for the opposite direction, as well. I don't know Cisco FR that well, but in at least some vendors' FR implementations, the "return" DLCIs do not have to have the same numbers as the "forward" ones. That actually enables you to number according to a pattern which indicates connectionality. And it also makes the DLCI switching table twice the size that Priscilla showed.
