Abstract
A communication system, a communication control method and a control program storage medium do not require loading of BGP for customer node and edge node and can prevent increasing of load. The communication system establishes a virtual private network for communication between a plurality of customer networks by forming a tunnel on a provider network. Edge communication devices are connected at input and output ends of the tunnel. The edge communication device has terminating means for terminating a routing protocol used in the customer network.
