Message forwarding method, device, line card chip and computer-readable storage medium

Abstract

Embodiments of the present application provide a message forwarding method and device, a line card chip and a computer readable storage medium, and relate to the technical field of communication. In the case that a first network entry message is received through any network interface, a virtual destination line, an overlay ARP pointer and a physical exit of the first network entry message are obtained according to a routing parameter of the first network entry message. In the case that the physical exit represents that an exit of the first network entry message is a remote chip, an inner layer parameter of the first network entry message is updated according to the virtual destination line and the overlay ARP pointer, a Fabric message header is added to the first network entry message according to the virtual destination line, and a second network entry message is obtained. The second network entry message is forwarded through a Fabric interface, so that the number of parameters carried in the Fabric message header can be reduced, the Fabric bandwidth occupied by the message is reduced, and the difficulty of global maintenance and management is reduced.
