and verify the connection.
Configuring Frame Relay to ATM Network Interworking Soft PVCs
This section describes how to configure a Frame Relay to ATM network interworking soft permanent
virtual channel (soft PVC).
Figure 20-8
shows a Frame Relay to ATM network interworking soft PVC
between Switch A and Switch B.
Figure 20-8 Frame Relay to ATM Network Interworking Soft PVC Example
To configure a Frame Relay to ATM network interworking soft PVC, perform the following steps,
beginning in EXEC mode:
The previous configuration steps are illustrated in the following section.
