A method and system for enabling packet based communications using MPLS protocol between routing devices located on different networks. A network management system is used to provide a conduit for MPLS protocol information to flow between a routing device on one network and a routing device on another network to set up packet based MPLS communications between the networks. The flow of MPLS protocol information through the network management system enables the assignment of MPLS labels to packet communication between the routing devices on different networks without the need for using a Control protocol. The network management system may include systems such as an operations support system and an element management system.
