Abstract:
1. A method for creating a forwarding table, applied in a provider backbone bridge (PBB) over hierarchical virtual private local area network services (H-VPLS) network comprising a source user facing-provider edge (UPE), a network provider edge (NPE) and a destination user facing-provider edge (UPE), load sharing links being between the NPE and the destination UPE, wherein the method comprises: receiving, by the NPE, a label distribution protocol (LDP) message, the LDP message carrying a backbone MAC address of the destination UPE and a load sharing negotiation parameter between the destination UPE and the NPE or the LDP message carrying an extended MAC address created according to the backbone MAC address and the load sharing negotiation parameter; obtaining, by the NPE, a plurality of extended MAC addresses of the destination UPE according to the LDP message; and creating a forwarding table for each extended MAC address, the forwarding table comprising the extended MAC address and a plurality of corresponding output ports.
