However, because the size of the forwarding entry resources of each interface board is different, after the interface board with smaller forwarding entry resources no longer has idle forwarding entry resources, it cannot continue to receive other forwarding entries issued by the CPU. , it will cause packet forwarding exception on the interface board

Abstract

The present application provides a message forwarding method and network equipment. The message forwarding method is applied to a network device, and the network device includes a CPU and at least two interface boards. The method includes: the CPU obtains the forwarding entry resource of each interface board; When posting an item, if it is detected that the first interface board no longer has idle forwarding table item resources, an ACL entry is generated based on the forwarding table item and sent to the first interface board, and the ACL entry is used to indicate the destination IP The packet whose address matches the IP address in the forwarding entry is forwarded to the second interface board, and the second interface board has idle forwarding entry resources. This application can achieve the effect that in the case of different sizes of forwarding table item resources of multiple interface boards, even if the interface board with smaller forwarding table item resources no longer has idle forwarding table item resources, the effect of normal forwarding of messages can still be guaranteed.

Description

technical field [0001] This application relates to network communication technology, in particular to a message forwarding method and network equipment. Background technique [0002] In current network equipment, in order to improve packet forwarding efficiency, multiple interface boards are usually set up, but the sizes of forwarding entry resources of the multiple interface boards are usually different. Generally, the forwarding entries are delivered to each interface board sequentially by the CPU. However, because the size of the forwarding entry resources of each interface board is different, after the interface board with smaller forwarding entry resources no longer has idle forwarding entry resources, it cannot continue to receive other forwarding entries issued by the CPU. , the packet forwarding exception occurs on the interface board. Contents of the invention [0003] This application provides a message forwarding method and device. [0004] The technical solu...
