Patent ID: 8750314

Claim:
A method for a link protection in a virtual private local area network, comprising: in a networking process of a virtual private local area network services (VPLS) network, a link protection device establishing a main tunnel and a standby tunnel of multi-protocol label switching (MPLS) traffic engineering (TE) for a link, and creating a VPLS forwarding table to organize information of the established MPLS TE main tunnel and standby tunnel; and when receiving a VPLS message, the link protection device searching the information of the MPLS TE main tunnel of transmitting the VPLS message according to a way of accessing the VPLS network of the VPLS message and the VPLS forwarding table, and if the found MPLS TE man tunnel is invalid, then transmitting the received VPLS message by adopting the standby tunnel of the MPLS TE main tunnel; wherein, the VPLS forwarding table comprises a VPLS broadcast forwarding table, a VPLS media access control (MAC) forwarding table, a TE fast reroute (FRR) table and a next hop output port table.
