Abstract

The present invention provides a MAC address learning method and device. The method is applied to a TRILL network. The TRILL network includes at least two areas. The RB equipment of the convergence layer in the TRILL network belongs to all areas in the at least two areas. The access layer in the TRILL network The RB devices in the TRILL network belong to one of at least two areas, and the RB devices in the TRILL network are all enabled with ESADI. The method includes: the RB device at the access layer receives the message sent by the local host; the RB device at the access layer learns the message The source MAC address of the document, generate the corresponding MAC entry; notify the source MAC address to other RB devices in the area to which the RB device of the access layer belongs, so that other RB devices in the area can learn the source MAC address and generate the corresponding MAC table item. Therefore, the present invention can save the MAC address space of the RB device at the access layer, and reduce the hardware resource consumption of the RB device at the access layer.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a MAC address learning method and device. Background technique [0002] The Transparent Interconnection of Lots of Links (TRILL) protocol introduces the design idea of ​​Layer 3 routing technology, namely Intermediate System-to-Intermediate System (IS-IS), into the Layer 2 network, thereby introducing The simplicity and flexibility of the second layer are organically integrated with the stability, scalability and high performance of the third layer, which is suitable for the needs of building large-scale two-layer networks. [0003] In the prior art, the TRILL network is logically fully connected, and each router bridge (RouterBridge, RB) in the TRILL network stores TRILL routes to other RBs, and each RB maintains a corresponding RB for the peer RB device. The TRILL header encapsulates or decapsulates the table to facilitate mutual access between the host connected...
