Example: PVC Switching Configuration
You can configure your router as a dedicated, DCE-only Frame Relay 
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 interface serial 
1 and 2. Frames with DLCI 100 received on serial 1 will be transmitted 
with DLCI 200 on serial 2 (see 
).
