Embodiment Construction

[0034] The embodiment of the present invention provides an isolation method within the scope of the entire VPLS network, including isolation between local access ACs and remote access ACs, and realizes flexible access control within the VPLS instance.

[0035] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0036] see figure 1 , is a schematic diagram of a flow for implementing network isolation between local ACs in the VPLS provided by Embodiment 1 of the present invention. A local isolation group is pre-configured on a PE, and its members include ACs that are connected to the PE and belong to the same VPLS instance but need to be isolated from each other. The process includes:

[0037] Step 101, when the AC-side incoming interface of the PE device receives the unicast message, the PE device searches for the outgoing interface of the message according to the MAC address forwarding table;

[0038] Step ...

Abstract

The invention discloses a network isolation method in a VPLS (Virtual Private LAN Service) and a device thereof. The network isolation method comprises the following steps: configuring a local isolation set on a PE (Portable Executable) device; adding local ACs (Attachment Circuits) of the PE device, which belong to the same VPLS example but are needed to be isolated, into the same local isolation set; and in a message forwarding process, limiting the forwarding of the message on the basis of a VPLS source filter principle when a message output interface AC and a message input interface AC belong to the same local isolation set, thereby realizing the isolation among the local ACs of the PE device. In the invention, a global insulation set is respectively arranged on PE devices at the local and an opposite end; ACs which are on the PE devices at the local end and the opposite end, belong to the same VPLS example but are needed to be isolated are added to the same global isolation set; and in a message forwarding process, on the basis of the VPLS source filter principle, the forwarding of the message is limited when a message output interface AC and a message input interface AC belong to the same global isolation set on the PE device at a message receiving end, thus the isolation between a local AC and a far-end AC of the PE device.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a network isolation method and device in VPLS. Background technique [0002] VPLS (Virtual Private LAN Service, Virtual Private LAN Service) is a point-to-multipoint L2VPN service provided 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 each site like a LAN (Local Area Network, local area network) same as in. [0003] VPLS provides Layer 2 VPN services. In VPLS, users are connected by multi-point networks. A series of virtual switches are created on PE (Provider Edge, operator border network equipment) and leased to users. The networking of virtual switches is similar to that of traditional switches. Exactly the same, in this way, users can realize their own LAN through MAN or WAN. ...
