Problems solved by technology

Due to the limited storage capacity of the FIB of the hardware forwarding engine of the service board, when the FIB capacity of the main control board is large, the service board may not be able to add all the routing entries in the FIB of the main control board, and some IP packets will appear in this case. The routing entries cannot be matched, resulting in the discarding of IP packets; in addition, when the FIB of the main control board is added to the service board, there will be a large number of routing entries on the service board. Selecting matching routing entries in routing entries affects the packet forwarding efficiency of service boards

Abstract

The invention provides a routing forwarding information adding method, a message forwarding method and device and a network device. The routing forwarding information adding method comprises the following steps: receiving FIB (forwarding information base) adding request information which is reported by a business board, wherein the FIB adding request information includes an object IP address (of an IP message) to be forwarded by the business board; inquiring a routing entry matched with the object IP address in an FIB of a main control board; sending the routing entry to the business board so that the business board can add the routing entry to the own FIB. According to the embodiment of the invention, the required FIB can be issued to the business board based on the request of the business board, and the problems of forwarding failure of the IP message and low forwarding efficiency caused by the factor that the FIB of the control board is wholly issued to the business board can be avoided.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a method for adding routing and forwarding information, a method and device for forwarding messages, and network equipment. Background technique [0002] Network devices such as routers and switches can support Internet Protocol (Internet Protocol, IP) routing and forwarding functions. Network devices usually include a main control board and multiple service single boards. The main control board mainly manages between networks, and is used to generate routing information tables (Routing Information Base, RIB) and forwarding information tables (Forwarding Information Base, FIB), and Send the generated FIB of the main control board to the hardware forwarding engine in the service single board; the service single board mainly forwards the IP message based on the FIB issued by the main control board. [0003] When the existing main control board sends the FIB t...
