Method and equipment for realizing VPN message forwarding

Abstract

The invention relates to a data forwarding technology in the field of network communication, discloses a method and equipment for realizing VPN message forwarding, and solves the problems of low forwarding efficiency and high equipment hardware cost caused by the forwarding mode in a traditional technology that forwarding needs to be carried out through the searching of a VPN route. When forwarding strategy of a strategy route is configured, if the configured forwarding strategy states that a matched message is forwarded in an appointed VPN, the next hop or an outbound interface is appointed after the VPN is appointed, and the appointed next hop or outbound interface belongs to the former appointed VPN. When a forwarding table is created by a strategy route management module for the corresponding forwarding strategy, related forwarding information needs to be searched in the VPN to which the appointed next hop or outbound interface belongs, and the strategy route forwarding table is created according to the forwarding information. In the process of forwarding the message, if the message is matched with the matching strategy of the strategy route, the message is directly forwarded according to the created forwarding table, and the VPN forwarding table is not required to be searched according to destination addresses. The method and the equipment are suitable for data forwarding.

Description

technical field [0001] The invention relates to data forwarding technology in the field of network communication, in particular to a method and equipment for realizing VPN network message forwarding based on policy routing. Background technique [0002] Policy routing is a technology for forwarding packets according to configured packet processing (including matching and forwarding) policies. When forwarding data packets, the packet is first filtered according to the configured matching strategy, and if the matching is successful, the packet is forwarded according to the configured forwarding strategy. The configured matching policy can be based on the standard and extended ACLs, or based on the length of the packet. The forwarding strategy is to control packets to be forwarded according to the specified forwarding strategy. At the same time, fields such as the IP priority of the packets can also be modified. Generally speaking, policy routing is an effective enhancement t...
