Problems solved by technology

However, due to the short deployment time of VPLS (Virtual Private LAN Service, virtual private local area network service), the corresponding standards have not been fully determined, and some common applications have not been defined. Networking requirements, or excessive restrictions on network organization, have brought certain obstacles to the large-scale deployment and wide application of VPLS technology

Embodiment Construction

[0029] The implementation of a system and method for mutual access between VPNs in a VPLS network proposed by the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] see figure 1 Shown is a system structure diagram of the present invention. The system structure is a system structure for mutual access between VPNs in the VPLS network of the present invention, and mainly consists of the following modules: a command configuration module 110, a MAC (Media Access Control, Media Access Control) learning module 120 and a forwarding module 130. in

[0031] The command configuration module 110 is responsible for configuring which VPNs can communicate with each other, because by default, VPNs cannot communicate with each other, and only after a certain configuration can the relevant VPNs be able to communicate with each other. In addition, the command configuration module 110 also includes command implementation, deletion a...

Abstract

The invention is for use in VPLS network system comprising a first PE device and a second PE device, both are respectively connected to the VPN1, VPN2 and VPN3. The system thereof comprises: a command configuring module used for making command configuration for the visits between VPNs; a MAC learning module used in learning strategy for modifying MAC address according to said command in order to implement mutual visit between VPNs; and a relay module used for relaying message according to the MAC address obtained from MAC learning module.

Description

technical field [0001] The present invention relates to the field of mutual access between VPNs in a VPLS network, in particular to a method for realizing multiple VPNs in a VPLS network environment without adding any second-layer or third-layer equipment and on the premise of administrator configuration authorization. A system and method for mutual access. Background technique [0002] Currently, with the large-scale deployment of MPLS (Multi-Protocol Label Switching, Multi-Protocol Label Switching), the MPLS VPN (Virtual Private Network, Virtual Private Network) technology is being widely used. In particular, MPLS L2 (Layer 2, two layers) VPN (VPLS) is more and more popular because of its convenient deployment, simple management, good isolation of public network and private network routing information, and reduction of the impact of user networks on operator networks. It is more and more welcomed by operators, and has been deployed and used on a large scale. However, due...
