1. A method of distributing virtual circuit identifiers associated with gateways in a network, comprising:
- receiving, at a first node, packets comprising a plurality of first virtual circuit identifiers associated with gateways in the network;
determining if any of the gateways are connected to the first node;
assigning second virtual circuit identifiers to connected gateways; and
initiating the transmission of a message to the connected gateways informing the connected gateways of the plurality of first virtual circuit identifiers.

Abstract
A network (100) includes multiple gateways (135, 140) and a router (105) connected to at least one of the multiple gateways (135, 140). The router (105) is configured to receive packets that include multiple first virtual circuit identifiers associated with the multiple gateways in the network (100), assign second virtual circuit identifiers to the at least one connected gateway, and initiate transmission of a message to the at least one connected gateway informing the gateway of the first virtual circuit identifiers.
