Abstract
A method is implemented by a node for enabling shortest path bridging in a network that is scalable to support sixteen million virtual local area network (VLAN) identifiers using multiprotocol label switching (MPLS) encapsulation. The method comprises allocating a tunnel label using a distributed tunnel label allocation algorithm, allocating a source label using a distributed source label allocation algorithm, assigning a bridge instance a service label, and distributing the tunnel label, source label and service label to other nodes in the MPLS network.
