Embodiment 1

[0018] figure 2 It shows the implementation process of the method for eliminating media access control revocation message flapping in VPLS provided by Embodiment 1 of the present invention. figure 1 It is an example of a network topology applied to the method for eliminating media access control revocation message flapping in the VPLS provided by the embodiment of the present invention. Among them, the network includes provider edge equipment PE (Provider Edge) and user edge equipment CE (Customer Edge). Among them, PE can be divided into user-side operator edge PE (User-end Provider Edge, UPE), network core layer edge (Network Provider Edge, NPE) and upper-layer operator edge equipment SPE (Superstratum Provider Edge). by figure 1 As an example, the method is detailed as follows:

Abstract

An embodiment of the invention provides a method and a device for eliminating media access control withdrawal message concussion in VPLS (virtual private LAN service). A media access control withdrawal message sent by a router includes router identification TLV (type-length-value) information, and when the router include router identification TLV information includes an identification of the local router, the media access control withdrawal message is abandoned. The method and the device for eliminating media access control withdrawal message concussion in VPLS solves the problem of media access control withdrawal message concussion in a VPLS network, so that system loss of the router is reduced and performances of a whole H-VPLS (hierarchy of VPLS) nuclear network can be improved.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a method and equipment for eliminating medium access control revocation message oscillation in VPLS. Background technique [0002] With the development of Layer 2 Virtual Private Networks (L2VPN) technology, virtual private LAN service (Virtual Private LAN Service, VPLS) technology is more and more applied in major networks at present, and in VPLS network In increasingly larger cases, the use of hierarchical VPLS (Hierarchy of VPLS, H-VPLS) technology has been applied on a large scale. [0003] Although the H-VPLS pseudowire solves the problem of VPLS traffic split horizon, loops may still occur. The existing VPLS-based spanning tree algorithm (Spanning Tree Protocol, STP) can be used to solve the traffic loop problem. However, in the VPLS network, the control plane will generate a media access control withdrawal (mac-withdraw) message. The transmission depends on...
