  • Systems and Methods for Implementing Multi-Topology Support for Label Distribution Protocol (LDP) of a Multiprotocol Label Switching Network
    Publication number: 20120275461
    Abstract: System and method for support multiple topology in Label Distribution Protocol of Multi-Protocol Label Switching (MPLS) network are disclosed. The system includes a number of network elements and a communication mechanism used to connect the network elements. The network elements discover LDP peers within the network topology, and create and maintain LDP sessions for each of the network topologies. The network elements further establish LSPs by mapping network layer routing information within each network topology to data link layer switches paths. Furthermore, the communication mechanism enables the network elements to advertise the multi-topology capability and exchange the mapping information of label and FECs within each network topology.
