Problems solved by technology

Although this method only deletes the CE-related entries, it is more efficient than the first method, but if the MAC address revocation message needs to carry a large amount of MAC addresses, a MAC address revocation message may not include all the MAC addresses that need to be updated. Many MAC addresses may be used, which may lead to the need to use multiple MAC address recovery messages, which will undoubtedly increase the network burden and the processing burden of PE devices. The MAC address update speed is still not ideal, and the MAC address convergence speed of the entire network is still very slow.

Embodiment Construction

[0055] Step 301, receiving a MAC address recovery message carrying the identifiers of the devices at both ends of the faulty PW.

[0056] The identifiers of the equipment at both ends of the faulty PW are the identifiers of the UPE-end equipment and the identifiers of the NPE-end equipment. This identifier may be any identifier that uniquely represents the device in the network, such as a Signature Switching Router ID (LSRID) or an IP address, MAC address, and the like.

[0057] Step 302 , judging whether the self is the NPE device among the devices at both ends of the faulty PW, if yes, execute step 303 , otherwise execute step 304 .

[0058] The judging method is arbitrary. For example, the identity of itself may be compared with the identity of the NPE end device, and if they are the same, it is judged that it is the NPE end device among the devices at both ends of the faulty PW.

[0059] Step 303: Delete the MAC address in the MAC address forwarding table with the faulty ...

Abstract

The invention discloses a method and a device for recycling an MAC address in a VPLS. The method comprises the following steps: receiving MAC address recycling information carrying marks of apparatuses at two ends of a fault link; judging whether the device is an NPE terminal apparatus in the apparatuses at two ends of the fault link or not, if so, deleting the MAC address using the fault link asan interface in an MAC address retransmission table according to the mark, and otherwise, deleting the MAC address using the link connected with the NPE apparatus in the apparatuses at two ends of the fault link as the interface according to the symbol. Then method and the device enable the VPLS network to generate a link active-standby changeover; in the process of recycling the MAC address, thequantity of the MAC address needed to be deleted by the NPE is greatly reduced, thereby the processing loads of the NPE apparatus is reduced, and the speed of updating the MAC address is improved.

Description

technical field [0001] The invention relates to the technical field of VPLS, in particular to a method and device for recovering MAC addresses in VPLS. Background technique [0002] VPLS (Virtual Private LAN Service) is an MPLS (Multiprotocol Label Switching) Layer 2 VPN technology that can provide a point-to-multipoint Layer 2 VPN service in a public network. VPLS enables geographically isolated user sites to be connected through MAN (Metropolitan Area Network, Metropolitan Area Network) or WAN (Wide Area Network, Wide Area Network), and makes the connection effect between various sites the same as in the same local area network LAN. Currently, H-VPLS (Hierarchy of VPLS, hierarchical VPLS) is widely used, and H-VPLS can extend the VPLS access range of service providers and reduce costs. [0003] LSP (Layered Service Provider, Layered Service Provider) is a network protocol interface, and H-VPLS can access the network through the LSP. Currently, the network that provides H...
