<p>The technical field of the invention relates to telecommunications, and in particular to a method and device for controlling message forwarding. The method comprises: dividing a first broadcast domain and a second broadcast domain; maintaining a first broadcast domain identifier at the interfaces of the public network side, while maintaining a second broadcast domain identifier at the interfaces of the accessing side; receiving the forwarding message, studying the source media access control (MAC) address of the message so as to achieve a corresponding relationship between the source MAC address, the receiving interface and the broadcast domain identifier, and mapping said broadcast domain identifier, whereafter an item from a source MAC address corresponding to the broadcast domain identifier is forwarded. The device comprises a division module, a preservation module, a receiving module and a mapping module. Thanks to the broadcast domain and mapping broadcast domain identifiers, there is no need to modify a forwarding engine chip of the current message forwarding device. The invention meets the requirements for an accessing side isolation in a two-layer network and realizes successful message forwarding.</p> |
