Method, route bridge and system for transmitting message

Abstract

The invention discloses a method, a route bridge and a system for transmitting a message, which are applied to the technical field of communication and aim to reduce signaling overhead in a transparent interconnection of lots of links (TRILL) network. The method comprises the following steps that: a first intermediate route bridge (RB) receives a nickname (Nickname) of an edge RB transmitted by a second intermediate RB; the first intermediate RB constructs an address notification message, wherein the address notification message comprises a virtual internet protocol (IP) address of the first intermediate RB and a virtual media access control (MAC) address; the first intermediate RB transmits the address notification message to the edge RB according to the Nickname of the edge RB, so that the edge RB transmits a free address resolution protocol (ARP) message to a server which accesses the TRILL network through the edge RB after the edge RB receives the address notification message, wherein the ARP message comprises the corresponding relation between the virtual MAC address and the virtual IP address. The method, the route bridge and the system are mainly used in a multi-gateway load-sharing technology of the TRILL network.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a message sending method, a router bridge and a system. Background technique [0002] At present, with the rapid popularization of the network and the deepening of the application, various value-added services have been widely deployed on the network, and the network bandwidth has also increased exponentially. Network load sharing has increasingly become the focus of attention. The multi-gateway load sharing protocol is a widely used protocol at present, which can effectively solve the problem of network load. [0003] Transparent Interconnection of Lots of Links (TRILL for short) protocol is a routing protocol based on link state calculation on a Layer 2 network. It passes Intermediate System to Intermediate System (IS for short) -IS) protocol, the device running the TRILL protocol is called a route bridge device (Route Bridge, RB for short), and the network composed of R...

Problems solved by technology

[0007] Embodiments of the present invention provide a message sending method, router bridge and system, which are used to solve the problem that when a certain intermediate RB fails in a TRILL network, the server connected to the intermediate RB accesses the TRILL network through a new intermediate RB When the new intermediate RB sends ARP packets for each server connected to the failure, the problem of wasting TRILL network resources is caused
