A method and a device for forwarding an MPLS packet, the method comprising: configuring an MPLS packet interface board in an ether switching device, allocating a private MAC address to a port number of the MPLS packet interface board, and establishing a correlation between the private MAC address and the public MAC address; obtaining the private MAC address and the port number corresponding to a destination public MAC address of the MPLS packet according to the correlation; substituting the private MAC address for the public MAC address in the MPLS packet; forwarding the MPLS packet to the corresponding port according to the private MAC address. The device comprises: an MPLS packet interface board arranged in an ether switching device, for providing a dedicated interface for MPLS packet forwarding; and a MAC address converting module, for converting between the public MAC address in the MPLS packet and the private MAC address in the ether switching device. According to the invention, various services based on MPLS, such as PWE3, L2VPN, MPLS traffic engineering and so on, can be supported on layer-2 and layer-3 ether switch chips.
