Message processing method, exit routing device and border routing device

Abstract

The invention provides a message processing method, an exit routing device and a border routing device. The method comprises the following steps: according to a destination internet protocol (IP) address and a source IP address of a received message, querying a routing list, wherein IP network segments and route attributes corresponding to the IP network segments are stored in the routing list; and when querying that the route attributes corresponding to the destination IP address and the source IP address are both private network routes, discarding the message. The exit routing device comprises a query module and a discarding module, wherein the query module is used for querying the routing list in accordance with the destination IP address and the source IP address of the received message; the IP network segments and the route attributes corresponding to the IP network segments are stored in the routing list; and the discarding module is used for discarding the message when the query module queries that the route attributes corresponding to the destination IP address and the source IP address are private network routes. By using the technical scheme provided by the invention, the problems that the configuration of the exit routing device is complicated and resources of a fast filter processor (FFP) are wasted due to the configuration of access control lists (ACL) in the prior art can be solved.

Description

technical field [0001] The present invention relates to network communication technology, in particular to a message processing method, an egress routing device and a border routing device. Background technique [0002] A virtual private network (Virtual Private Network; abbreviated as: VPN) is a temporary and secure connection established through a public network, and is a safe and stable tunnel passing through the public network. Multiprotocol Label Switching (MPLS for short) is a protocol that supports multiple network layers, such as: Internet Protocol Version 4 (IPv4 for short), Internet Protocol Version 6 (Internet Protocol Version 4) Protocol Version 6; referred to as: IPv6), Internetwork Packet Exchange protocol (referred to as: IPX), etc., and is compatible with Asynchronous Transfer Mode (Asynchronous Transfer Mode; referred to as: ATM), Frame Relay, Ethernet, Point to Point Protocol (Point to Point Protocol; referred to as: PPP) and other link layer technologies,...

AI Technical Summary

Problems solved by technology

[0005] The present invention provides a message processing method, egress routing equipment and border routing equipment, which are used to solve the defects caused when each VPN in BGP / MPLS IP-VPN accesses the Internet by configuring super VPN and configuring default routes in the prior art, Simplifies the configuration of network egress devices and saves FFP resources
