Abstract:
1. A method for automatically configuring a virtual circuit (VC), comprising: receiving a packet, by a router, the router configured as being absent a VC configuration for the packet source, the packet including a source VC identification indicating that the packet was sent on the VC; determining, by the router if the source VC identification indicates an unconfigured VC; and configuring the VC, by the router, if the source VC identification indicates an unconfigured VC; further comprising: determining whether the source VC identification is valid if the source VC identification indicates an unconfigured VC; and rejecting the VC if the source VC identification is invalid; wherein the configuring includes bringing the VC to the point that it can be recognized by a router; and wherein the determining whether the source VC identification is valid includes determining whether the source VC identification is within a preset valid range.
