Embodiment 1

[0038] This embodiment provides a method for clearing a media access control address, including:

[0039] The NPE device receives the notification of clearing the MAC address. When the notification does not carry a specific identifier, it clears the B-MAC address table corresponding to the VPLS and forwards the notification; when the notification carries a specific identifier, it forwards the notification;

[0040]After the UPE device receives the above notification, if the notification does not carry a specific identifier, clear the B-MAC address table corresponding to VPLS; when the notification carries a specific identifier, clear the B-MAC address table corresponding to the specific identifier in the C-MAC address table item.

[0041] In order to implement the above method, the UPE device needs to assign a user ID to the CE device connected to it. Each CE device is assigned a user ID. If a CE device is connected to two UPE devices, the two UPE devices will assign the same ...

Embodiment 2

[0074] Referring to FIG. 5, this embodiment provides a system for clearing media access control addresses, including:

[0075] The edge device of the network provider is used to receive the notification of clearing the media access control address. When the notification does not carry a specific identifier, clear the backbone network media access control address table corresponding to the VPN and forward the notification; when the notification carries a specific identifier, forward the notification. Notice;

[0076] The user-side provider edge device is used to clear the backbone network media access control address table corresponding to the VPN when the notification does not carry a specific identifier after receiving the notification forwarded by the network provider edge device; when the notification carries a specific identifier, Clear the backbone network media access control address entry corresponding to the specific identifier in the user media access control address ...

Embodiment 3

[0089] Referring to Figure 6, this embodiment provides a network provider edge device, including:

[0090] a notification receiving module, configured to receive a notification of clearing the media access control address;

[0091] The notification processing module is used to clear the backbone network media access control address table corresponding to the virtual private local area network when the notification received by the notification receiving module does not carry a specific identifier, and forward the notification; when the notification carries a specific identifier, forward the notification.

Abstract

The present invention discloses a method, a system and an equipment for removing the Media Access Control address, which belong to the communication field. The method comprises: when the notice received by an NPE equipment does not carry a particular identifier, the B-MAC address table corresponding to the VPLS is removed, and the notice is transmitted; when the notice carries a particular identifier, the notice is transmitted; when the notice received by a UPE equipment does not carry a particular identifier, the B-MAC address table corresponding to the VPLS is removed; and when the notice carries a particular identifier, the B-MAC address table corresponding to the particular identifier in a C-MAC address table is removed. The system comprises a network provider edge equipment and a user side provider edge equipment. By adding the particular identifier in the notice removing the MAC address, the present invention avoids the needless MAC address learning of the NPE equipment and the UPE equipment, and reduces the impact to the network equipment.

Description

technical field [0001] The invention relates to the communication field, in particular to a method, system and equipment for clearing media access control addresses. Background technique [0002] VPLS (Virtual Private LAN Service) is a L2VPN (Layer 2 Virtual Private Network) technology based on MPLS (Multi-Protocol Label Switching) and Ethernet technology. VPLS can implement multipoint-to-multipoint VPN networking. VPLS provides a more complete solution for many operators who originally used point-to-point L2VPN services, and can simplify the management of internal routing information for users. [0003] In VPLS networking, it is generally required to establish a full connection PW (Pseudo wire, pseudo-link) between PE (Provider Edge, provider edge) devices, which is not conducive to network expansion; and H-VPLS (Hierarchical VPLS, hierarchical Standardized VPLS) only requires full connection PW to be established between NPE (Network Provider Edge, network provider edge) d...
