Example Embodiment

[0033] In order to make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that the embodiments in the application and the features in the embodiments can be combined with each other arbitrarily if there is no conflict.

[0034] figure 2 This is a flowchart of the method for forwarding data messages in this embodiment.

[0035] S201 establishes a routing interface attribute table, and uses port number, inner virtual local area network identifier (VLANID), and outer VLAN ID as the index of the routing interface attribute table;

[0036] The routing interface attributes recorded in the interface attribute table include: VPN attributes of the routing interface, whether the status of the routing interface is up or down, whether multicast is enabled, etc.;

[0037] S202 determines the index according to the type and ...

Abstract

The invention provides a method for forwarding a data message and a route device, wherein the method comprises the following steps of: establishing a route interface attribute list with a port number, an inner-layer VLAN ID (Virtual Local Area Network Identity) and an outer-layer VLAN ID as an index of the route interface attribute list; determining the index according to the type and the configuration of a route interface; analyzing the received data message, finding out the route interface attribute list according to the port number, the inner-layer VLAN ID and the outer-layer VLAN ID according to an analyzed result, and obtaining the attribute of the route interface; and carrying out route forwarding according to the received data message information and the route interface attribute. According to the method for forwarding the data message, forwarding list options and forwarding processes of different types of route interfaces are unified.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a method and routing equipment for forwarding data messages. Background technique [0002] With the rapid development of the network today, network processor-based routing devices are more and more widely used due to their flexible programmability and high processing performance, but their supportable instruction space and resources are limited. [0003] Routing port is a physical port on the routing device, which is used as the routing interface of the routing device to configure Layer 3 routing. The routing port sub-interface is a sub-interface divided by the routing port based on a virtual local area network (Virtual Local Area Network, VLAN), and can also be used as a routing interface of a routing device. Routing port sub-interfaces can be further divided into routing port VLAN sub-interfaces and routing port QinQ (abbreviation for 802.1Q in 802.1Q) sub-interfaces. It is ...
