Abstract

The invention provides a method and equipment for removing media access control (MAC) forwarding table entries. The method comprises the following steps: a first route bridge (RB) detects that the topology of a network to which a local end station is connected changes; and the first RB sends a first message to a second RB so as to enable corresponding forwarding table entries to be removed after the second RB receives the first message, wherein the second RB refers to an RB which is configured with at least one same VLAN as the first RB. According to the method and the equipment in the embodiment of the invention, MAC forwarding table entries of related equipment of the whole network can be timely removed to avoid forwarding errors when the topology of the network to which the local end station is connected changes.

Description

technical field

[0001] The present invention relates to network communication technology, in particular to a method and device for clearing media access control (Media Access Control, MAC) forwarding entries. Background technique

[0002] The Transparent Interconnect of Lots of Links (TRILL) protocol is a routing protocol based on link state calculations on a Layer 2 network. The device running the TRILL protocol is called a Route Bridge (RB). A network composed of RBs is called a TRILL network (TRILL Campus). TRILL can implement a large Layer 2 network and overcome the shortcomings of traditional Layer 2 networks such as low bandwidth utilization and slow convergence time.

[0003] The traditional Layer 2 local Ethernet (native ethernet) can be connected to the TRILL network. In order to improve the reliability of the access network, it is generally connected through multi-homing. If the topology of the network accessed by the terminal (End Station, ES) switches, the RB a...
