Problems solved by technology

[0006] However, in the ERPS ring network, when the master node and neighbor nodes are in the blocking state of the STP control instance, they cannot pass the received ERPS protocol message from the switch chip to the processor for processing, resulting in an error in the calculated status of each ERPS node.

Abstract

The invention provides a message forwarding method and equipment. A processor in the equipment determines that a spanning tree protocol STP control instance of a ring protection link RPL port is switched from a forwarding state to a blocking state, and configures an extended access control table entry for a switch chip; the priority of the extended access control table item is higher than that of a global Ethernet protection switching protocol ERPS access control table item; the switch chip is used for mapping a first ERPS protocol message which is received by the RPL port and belongs to a control virtual local area network (VLAN) to the STP reservation instance in a forwarding state based on the extended access control table item; the received first ERPS protocol message is sent to a processor in the STP reservation instance; wherein the control VLAN is associated with the STP control instance; and the processor maps the received first ERPS protocol message from the STP reservation instance to the STP control instance, and sends the received first ERPS protocol message to an ERPS protocol stack.

Description

technical field [0001] The present application relates to communication technologies, and in particular to a message forwarding method and device. Background technique [0002] ERPS (Ethernet Ring Protection Switching, Ethernet Ring Protection Switching) is an Ethernet ring link layer technology with high reliability and stability. It can prevent the broadcast storm caused by the data loop when the Ethernet ring is complete, and can quickly restore the communication path between the nodes on the ring network when the link failure occurs on the Ethernet ring, and has a high convergence speed. [0003] The user configures each device on the ERPS ring as a different node, including: the master node (Owner), the neighbor (Neighbor) node, the interconnection (Interconnection) node, and the normal (Normal) node. [0004] The master node and neighbor nodes are connected through RPL (Ring Protection Link). The ERPS ring network can be divided into control VLAN and protection VLAN: ...
