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:

Serial 1, DLCI 102 to serial 2, DLCI 201—DCE switching

Serial 1, DLCI 103 to serial 3, DLCI 301—DCE/DTE switching

Serial 2, DLCI 203 to serial 3, DLCI 302—DCE/DTE switching

DLCI 400 is also defined for locally terminated traffic.
