Problems solved by technology

During the link failure process, port P2 of transit node C and port P1 of transit node D cannot receive GVRP registration packets for a long time and reach the aging event of VLAN 10 registration information. These ports no longer have registration information of VLAN 10. Therefore, after transit node C and transit node D receive the Complete_Flush_FDB message, although they can immediately unblock the port connected to the fault recovery link, port P2 of transit node C and port P1 of transit node D need to complete the VLAN 10's dynamic learning process, therefore, the flow cannot be restored immediately, causing the flow to be interrupted for a period of time

Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] After the node on the RRPP ring receives the GVRP registration message for the VLAN through the first port that enables the RRPP feature, it stores the registration information of the VLAN on the first port, and starts on the second port that enables the RRPP feature ( UP), the registration information of the VLAN is synchronized to the second port for storage.

[0022] When the first port or the second port goes offline (Down), the registration information of the VLAN stored on the first port or the second port is deleted.

[0023] When the first port is switched from Down to UP, immediately synchronize the registration information of the VLAN stored on the second port; or, when the second port is switched from Down to UP, immediately sync...

Abstract

The present invention provides a dynamic learning method of GARP VLAN registration protocol (GVRP) and network nodes, wherein, after the network nodes on a rapid ring protect protocol (RRPP) ring receives GVPR registration messages aiming at a virtual local area network (VLAN) through a port of the enabling RRPP property, the registration messages of the VLAN are then storied in the port, and at the same time, the registration messages of the VLAN are synchronized with the enabling RRPP property and are then storied on other activated ports. Therefore, it is not necessary to perform a dynamiclearning of registration messages of a VLAN after a link switch caused by link fault or by link recovery, transmission of data messages on the link after switch can be realized directly and the flow can be recovered quickly.

Description

technical field [0001] The invention relates to network communication technology, in particular to a dynamic learning method and network node of a virtual local area network registration protocol (GVRP, GARP VLAN Registration Protocol) of a general attribute registration protocol. Background technique [0002] Rapid Ring Protection Protocol (RRPP, Rapid Ring Protection Protocol) is a link layer protocol specially used for Ethernet rings. It can prevent broadcast storms caused by data loops when the Ethernet ring is complete. When any link on the Ethernet ring is disconnected In this case, the communication link between the nodes on the ring network can be quickly restored. Generally, an Ethernet ring with RRPP enabled is called an RRPP ring. [0003] Usually an RRPP ring mainly includes: master node and transit node, such as figure 1 As shown in the figure, the master node and the transit node are RRPP-enabled network devices and have ports connected to the RRPP ring. The t...
