Example: PVC Switching Configuration
You can configure your router as a dedicated, DCE-only Frame R elay
switch. Switching is based on DLCIs. The incoming DLCI is exam-
ined, and the outgoing interface and DLCI are determined. Switching
takes place when the incoming DLCI in the packet is replaced by the
outgoing DLCI, and the packet is sent out the outgoing interface.
In this example, the router switches two PVCs between interf ace se rial
1 and 2. Frames with DLCI 100 received on serial 1 will be transmitted
with DLCI 200 on serial 2 (see Figure 13-4).
