Configuring Frame Relay to ATM Service Interworking PVCs
This section describes configuring Frame Relay to ATM service interworking permanent virtual
channels (PVCs). A Frame Relay to ATM service interworking PVC is established as a bidirectional
facility to transfer Frame Relay to ATM traffic between a Frame Relay user and an ATM user. The upper
user protocol encapsulation (FRF.3, RFC 1483, RFC 1490, RFC 1577) mapping can be enabled with the
translation option of the
frame-relay pvc
command.
Figure 20-4
shows an example of a Frame Relay to ATM service interworking PVC between Frame
Relay User A and ATM User D through an ATM network.

Note
VPI and VCI values can change when traffic is relayed through the ATM network.
