Embodiment Construction

[0017] In order to make the object, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below with reference to the accompanying drawings and examples.

[0018] see figure 1 , figure 1 It is a flowchart of a hello message sending method when a neighbor relationship is established in an embodiment of the present invention, and is applied in a TRILL network. The method includes:

[0019] Step 101, when receiving the Hello message sent by the new neighbor routing bridge RB, if the timer T has started, the virtual local area network VLAN to which the Hello message belongs is added to the first VLAN set corresponding to the new neighbor RB, If the timer T is not started, start the timer T, and add the VLAN to which the Hello message belongs to the first VLAN set corresponding to the new neighbor RB.

[0020] In this step, the timer T is predefined. When there is a new neighbor RB accessin...

Abstract

The invention provides a Hello message sending method and device in a neighborhood relationship establishing process. The hello message sending method comprises the following steps of: when receiving a Hello message sent by a new neighborhood RB (Routing Bridge), if a timer T has been started already, adding a VLAN (Virtual Local Area Network) to which the Hello message belongs into a first VLAN set corresponding to the new neighborhood RB, and if the timer T is not started, starting the timer T and adding the VLAN to which the Hello message belongs into the first VLAN set corresponding to the new neighborhood RB; and after the timer T is time out, generating a second VLAN set according to the first VLAN set corresponding to the new neighborhood RB, and sending the Hello message by each VLAN in the second VLAN set. According to the Hello message sending method and device disclosed by the invention, the sending number of the Hello messages in the neighborhood relationship establishing process can be reduced.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and a device for sending a hello message when establishing a neighbor relationship. Background technique [0002] TRILL is a link layer (L2) networking standard recommended by the Internet Engineering Task Force (IETF) to address the shortcomings of the Spanning Tree (STP) protocol in large data centers. [0003] In a TRILL network, a device running the TRILL protocol is called a routing bridge (RB, Routing Bridge) device, and the directly connected RB devices on the same link use Hello packets to exchange information. A designated RB (DRB) will be elected between RBs on the same link, and the DRB will select a designated VLAN for subsequent encapsulation of TRILL control packets and data packets, and assign a VLAN to each enabled VLAN on the link. The only send and receive ports act as designated VLAN forwarders (AVF) for that enabled VLAN. When an AVF is assign...
