Embodiment approach

[0061] Based on the above analysis, an implementation manner of the embodiment of the present invention is as follows:

[0062] The spine node receives the LTM message or LTR message sent by the leaf node in the maintenance set; when the LTM message or LTR message is used to maintain the link detection information table (by adding a custom TLV identifier in the LTM message or LTR message To illustrate that the LTM message or LTR message is used to maintain the link detection information table and is distinguished from the LTM message or LTR message currently used for link tracking), the corresponding maintenance information of the LTM message or LTR message is obtained. set level, VLAN and receiving port; after that, the spine node judges whether there are records corresponding to the maintenance set level, VLAN and receiving port in the link detection information table; if yes, the link detection information table will not be updated; if not, then in The link detection inform...

Abstract

The invention discloses a method and a device for chain detection in a TRILL network. The method includes the following steps that a spine node confirms a port where a leaf node corresponding chain is located, and confirms a VLAN corresponding to a maintenance association; and the spine node confirms all ports of the VLAN, and closes CCM transmitting functions of other ports, except for the port where the leaf node corresponding chain is located, of all ports. The method and the device can avoid CCM frequent interaction among different maintenance associations, and reduces waste of network broadband resources.

Description

technical field [0001] The invention relates to the communication field, in particular to a link detection method and equipment in a TRILL network. Background technique [0002] CFD (Connectivity Fault Detection, connectivity error detection) is an end-to-end OAM (Operations, Administration and Maintenance) mechanism based on VLAN (Virtual Local Area Network, Virtual Local Area Network) in the Layer 2 network. It is used to detect link connectivity, confirm faults, and determine the location of faults in a Layer 2 network. In the CFD network, MD (Maintenance Domain) refers to a network or a part of the network covered by connectivity error detection. The concept of level (level) is introduced in MD. MD is divided into eight levels, with integer 0 ~7 means that the larger the number, the higher the level, and the larger the range of MDs; and different MDs can be adjacent or nested, but cannot cross, and nesting can only be nested from high-level MDs to low-level MDs. set. ...
