Abstract
This invention discloses a method, apparatus, and system for packet transmission. The method for packet transmission includes: configuring the two logical interfaces of a bidirectional tunnel to operate in bridge mode; at the first logical interface of the two, encapsulating Layer 2 packets and the protocol type information in tunnel packets and transmitting the packets to the peer through the bidirectional tunnel; at the second logical interface of the two, transmitting the tunnel packets to the corresponding Layer 2 protocol stack for processing according to the protocol type information in the received tunnel packets. The present invention enables the logical interfaces of a bidirectional tunnel to operate as Layer 2 ports to transmit Layer 2 packets.
