Frame Relay to Frame Relay Interworking Soft PVC Configuration Example
This section provides an example of a Frame Relay to Frame Relay network interworking soft PVC
configured between Switch A and Switch B, as shown in Figure 20-7. The source (active) side is serial
interface 0/1/0:5 on Switch A.
Step 1 Use the show vc interface serial command to determine that data-link connection identifier (DLCI) 43
is available on serial interface 0/1/0:5 on Switch A:
Switch-A# show vc interface serial 0/1/0:5
Interface Conn-Id Type X-Interface X-Conn-Id Encap Status
Serial0/1/0:5 54 SoftVC Serial3/0/0:3 54 SoftVC UP
Serial0/1/0:5 55 SoftVC Serial3/0/0:2 55 SoftVC UP
Serial0/1/0:5 56 SoftVC ATM0/1/3 0/45 SVC UP
Serial0/1/0:5 66 SoftVC ATM1/1/0 0/100 SoftVC UP
Step 2 The destination (passive) side is a Frame Relay serial interface 0/0/1:9 on Switch B.
Step 3 The ATM address for the destination serial interface 0/0/1:9 on Switch B is
47.0091.8100.0000.00e0.1e79.8803.4000.0c81.8010.00.

Step 5 Configure the network interworking soft PVC from Switch A beginning in global configuration mode.
Switch-A(config)# interface serial 0/1/0:5
Switch-A(config-if)# frame-relay soft-vc 43 dest-address
47.0091.8100.0000.00e0.1e79.8803.4000.0c81.8010.00 dlci 255
Note If the soft PVC originates and terminates on a Frame Relay interface, the default interworking
type is network interworking. You do not need to specify the interworking type explicitly.
