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).
