摘要：
A method and apparatus for processing a signal on an intermediate network node at an edge of a provider packet-switched network to support a link-layer virtual private network includes receiving a signal on a particular interface. The particular interface is for a direct communication link to a customer network node outside the provider network. It is determined whether the signal indicates that the particular interface is changing from an inactive state to an active state, whereby the signal is called first sign of life (FSOL). If it is determined that the signal is FSOL, then configuration data is determined for configuring the particular interface for the particular virtual private network. The signal is processed based on the configuration data. These techniques allow a dynamic response to new signals on a customer interface without human intervention by the provider.
