TRILL NETWORK INTERCONNECTION METHOD, DEVICE AND SYSTEM

摘要

The present invention relates to the technical field of communications. Disclosed are a TRILL network interconnection method, device and system, capable of solving the problem of low packet forwarding efficiency due to the fact that a great quantity of hardware resources need to be allocated for each edge route-bridge (RB) to support packet encapsulation and decapsulation during interconnection between data centers (DC). The method of the present invention comprises: the first edge RB of a first DC receives RB identification information transmitted by the second edge RB of a second DC, the RB identification information carrying the combination of the identification (ID) of a root-RB in a second DC and the ID of the second DC; and the first edge RB establishes a distribution tree forwarding entry according to the RB identification information, such that the packet can be transmitted according to the distribution tree forwarding entry. The present invention is mainly used in the interconnection process between DCs.
