Example: Hybrid DTE/DCE PVC Switching
Routers can also be configured as hybrid DTE/DCE Frame Relay
switches (see Figure 13-6).
Figure 13-6:Hybrid DTE/DCE PVC Switching
In this example, Router B acts as a hybrid DTE/DCE Frame Relay
switch. It can switch frames between the two DCE ports and between
a DCE port and a DTE port. Traffic from the Frame Relay network can
also be terminated locally. In the example, three PVCs are defined as:
z
Serial 1, DLCI 102 to serial 2, DLCI 201—DCE switching
z
Serial 1, DLCI 103 to serial 3, DLCI 301—DCE/DTE switching
z
Serial 2, DLCI 203 to serial 3, DLCI 302—DCE/DTE switching
DLCI 400 is also defined for locally terminated traffic.
