Configuring Soft PVCs

Soft PVCs are a combination of SVCs and PVCs. SVCs are set up on the inside of the path among ATM switch routers, and PVCs are set up between an edge ATM switch router and the terminating device (such as a router).

Soft PVCs require less manual configuration than PVCs. With soft PVCs, you need to configure only the destination ATM switch router in the path and PVCs on the devices that terminate the softPVC (such as a router).
