ABSTRACT:
Techniques are described for dynamically configuring an interface in a network service provider. The techniques allow dynamic configuration of, for example, a dual stacked interface that includes both Internet Protocol version 6 (IPv6) and Internet Protocol version 4 (IPv4) on the same layer 2 link. In this way, a customer network having an existing IPv4 connection to a network service provider will be able to run both IPv4 and IPv6 over the same interface. A network device within the network service provider may receive a control packet from a subscriber device. The packet may be received on an ATM hybrid permanent virtual circuit (PVC) that supports multiple interface columns. The network device is capable of auto-sensing multiple packet protocols and may dynamically create multiple interface columns over the same ATM interface based on the encapsulation type of the received packets.
