VPN realizing method

Abstract

The invention discloses an executing method and network of virtual specific network, which comprises the following steps: switching computer of virtual specific network region in the brink equipment of customer side; dividing mark of corresponding port on the brink equipment of customer side as specific virtual LAN of switch-in virtual specific network regional user; allocating virtual specific network region on the brink equipment of network side; adding the switch-in virtual LAN circuit in the virtual specific network region; allocating the switch-in velocity limit in the circuit; allocating general route to connect tunnel GRE on the brink equipment of network side; regarding GRE tunnel as one specific circuit in the virtual specific network region; realizing rapid deployment for virtual specific network.

Description

technical field [0001] The invention relates to a method for fast interconnection and intercommunication across regional networks and wide area networks when a virtual private network is deployed in the communication field. Background technique [0002] With the rapid development of the global Internet, the level of informatization of the people is getting higher and higher. Cross-regional state agencies and large enterprises have also requested to realize cross-regional interconnection in a private security network, enabling employees to work remotely at home, headquarters Share report data with branches, etc., and this demand is becoming stronger and stronger. [0003] At present, relatively mature VPN (virtual private network) technologies mainly include L2TP (Layer Two Tunnel Protocol, Layer Two Tunneling Protocol), MPLS (Multiprotocol Label Switching) virtual private network, etc., among which L2TP mainly adopts PPP (point to point) tunnel extension technology, althoug...

[0003] At present, relatively mature VPN (virtual private network) technologies mainly include L2TP (Layer Two Tunnel Protocol, Layer Two Tunneling Protocol), MPLS (Multiprotocol Label Switching) virtual private network, etc., among which L2TP mainly adopts PPP (point to point) tunnel extension technology, although it is suitable for employees to work at home, but it is not suitable for a large amount of data access between branches of large enterprises, between branches and headquarters; and MPLS virtual private network, further on the network layer To divide services, different traffic engineering can be adopted for different services, but the core layer network and aggregation layer network need to support the MPLS protocol, and the construction cost is relatively high. At present, it is urgent to provide an Under the premise of modification, provide a private private network method that can realize cross-regional interconnection of large enterprises and various state agencies, and is simple in configuration, easy to manage and maintain, and reliable
