Problems solved by technology

[0008] Since the forwarding of unicast packets on the current gateway device needs to use the loopback interface, the resources of the loopback interface will be wasted, and the forwarding performance of unicast packets is limited by the number of loopback interfaces

Abstract

The invention discloses a message transmission method and a gateway device. The method comprises the steps that: a first exchange chip receives a unicast message; if the unicast message is a TRILL (Transparent Interconnection of Lots of Links) message, the first exchange chip decapsulates the TRILL header and the outer-layer Ethernet header of the TRILL message to obtain the Ethernet message in the TRILL message and sends the Ethernet message to a second exchange chip serving as the agent exchange chip of the first exchange chip, and the second exchange chip performs IP forwarding on the Ethernet message; if the unicast message is the Ethernet message, the first exchange chip inquires the virtual interface MAC list of the device according to a target MAC address carried in the inner-layer Ethernet header of the Ethernet message; if the virtual interface MAC list of the device has no record corresponding to the MAC address, a MAC forwarding list and a Nickname forwarding list are inquired according to the target MAC address and VLAN of the Ethernet message to perform TRILL forwarding. According to the message transmission method and the gateway device, loopback interface resources can be saved.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a message transmission method and equipment based on a TRILL (Transparent Interconnection of Lots of Links, transparent interconnection of multiple links) network. Background technique [0002] TRILL is a technical standard for large-scale Layer 2 networks, and it is used to solve the following problems in STP (Spanning Tree Protocol, Spanning Tree Protocol) networks: some links are blocked, links are not fully utilized; the forwarding path of data flow may not be the optimal path The convergence time of topology changes is slow, etc. In addition, the advantages of TRILL technology include: all links are in working state, making full use of link bandwidth; using the shortest path for forwarding; supporting multi-path load sharing; fast convergence time of topology changes, etc. [0003] Such as figure 1 As shown, it is a schematic diagram of a TRILL network runn...
