This is what section 4.2.1 states. Each CE is configured to communicate with its corresponding PE with the set of DLCIs given above; for example, CE0 is configured with DLCIs 100 through 109. OSPF is configured to run over each DLCI. In general, a CE is configured with a list of circuits, all with the same layer 2 encapsulation type, e.g., DLCIs, VCIs, physical PPP interface etc. (IP-only layer 2 interworking allows a mix of layer 2 encapsulation types). The size of this list/set determines the number of remote CEs a given CE can communicate with. Denote the size of this list/set as the CE's range. It just says that DLCIs are configured between PE and CE. OSPF is is run over those DLCIs. Since PE transports L2 packets originated on these DLCIs to the remote CEs transparently, hence the OSPF is being run between the connecting CEs and not between a CE-PE pair.
