Problems solved by technology

However, the function of the hardware aging mechanism is single and inflexible. It can only adopt a uniform aging time for all MAC addresses. The traditional VPLS MAC address aging is also implemented by the same hardware mechanism as the ordinary MAC aging mechanism. Therefore, it cannot cope with different Requirements for Configuring Different MAC Aging Time in VPLS Instances

Embodiment Construction

[0058] The solution of the embodiment of the present invention mainly includes: after constructing the VPLS instance, receive the message from the remote side and / or the local side to perform MAC address query; create or update the VPLS MAC aging table according to the query result; when the pre-configured corresponding After the aging time of the VPLS instance arrives, the MAC address aging operation is performed according to the MAC aging software linked list and the VPLS MAC aging table, so as to realize that different MAC aging times can be configured separately for different VPLS instances as required, so as to meet the flexibility of the business sexual needs.

[0059] Such as figure 1 As shown, an embodiment of the present invention proposes a method for VPLS-based MAC address aging, including:

[0060] Step S101, after constructing the VPLS instance, obtain messages from the remote side and / or the local side;

[0061] Step S102, performing source MAC address learning...

Abstract

The invention relates to a method and device for aging an MAC (media access control) address based on VPLS (virtual private LAN service). The method comprises the following steps of: obtaining a message from a remote-end side and / or a local side after a VPLS example is constructed, performing source MAC address learning on the message, creating or updating a VPLS MAC aging table according to a learning result of the MAC address; when the predetermined aging time corresponding to the VPLS example is reached, performing MAC address aging operation according to an MAC aging software link table and the VPLS MAC aging table. Different MAC aging times can be respectively allocated as required by aiming at different VPLS examples, and therefore, the limit that all the VPLS examples can only be aged at the same time is overcome and the flexibility requirement of the service is met.

Description

technical field [0001] The invention relates to the technical field of network data communication, in particular to a method and device for VPLS-based MAC address aging. Background technique [0002] VPLS (Virtual Private LAN Services) is a service similar to LAN (Local Area Network) on MPLS (Multi-protocol Label Switching) network, which enables users to Simultaneous access to the network from multiple geographically dispersed points, and mutual access, as if these points were directly connected to the LAN. VPLS combines the advantages of Ethernet and MPLS technology. It is a simulation of all the functions of traditional LAN. Its main purpose is to connect multiple LANs that are geographically isolated and composed of Ethernet through the MPLS network provided by the operator, making them like a LAN. To work like that, thus forming a virtual private network. [0003] Through MAC address learning, a corresponding MAC address table is generated on each PE (Provider Edge, o...
