Embodiment Construction

[0042] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0043] figure 2 A flowchart of a method for establishing an IS-IS neighbor provided by an embodiment of the present invention, such as figure 2 As shown, the specific steps are as follows:

[0044] Step 201: the device sends a Hello packet from an IS-IS interface.

[0045] Step 202: The device first inquires whether the neighbor encapsulation abort flag for the interface is set, if so, executes step 203; otherwise, executes step 204.

[0046] Step 203: The device finds the neighbor information corresponding to the abort flag from the neighbor database of the interface, starts from the next neighbor information of the neighbor information, and encapsulates each neighbor information into the Neighbor field of the Hello message in turn, and goes to step 205.

[0047] The Neighbor field is the data part of the Hello packet and is us...

Abstract

The invention provides a method and device for building a middle system to a middle system neighborhood. The method comprises the steps that when equipment sends a Hello message from an IS-IS interface, whether the equipment is provided with a neighborhood packaging stopping mark for the interface is judged, if yes, all neighborhood messages are packed into the Hello message from the next neighborhood message of the neighborhood message corresponding to the stopping mark in the neighborhood database of the interface, and if not, all the neighborhood messages are packed into the Hello message in sequence from the first neighborhood message of the database; when the neighborhood messages reach an interface MTU but not reach the tail of the neighborhood database, the neighborhood packaging stopping mark is set according to the last packed neighborhood message, and a neighborhood message unpacking mark is set in the Hello message. The method and device for building the middle system to the middle system neighborhood achieve the support of a large network from an IS-IS protocol.

Description

technical field [0001] The present invention relates to the technical field of Intermediate System-to-Intermediate System (IS-IS, Intermediate System-to-Intermediate System), in particular to a method and device for establishing an IS-IS neighbor. Background technique [0002] As an internal gateway dynamic routing protocol, IS-IS protocol has gradually been widely used because of its simple configuration and maintenance, good scalability and support for large-scale networks. Mainstream equipment manufacturers have achieved good support for it. [0003] The premise of the IS-IS protocol is to maintain the neighbor relationship with peripheral devices. Through the maintenance of the neighbor relationship, network topology information is collected and route calculation is performed. Among them, the hello message is used to discover and establish neighbors and to maintain and maintain the subsequent neighbor relationship. [0004] figure 1 The existing process of establishin...
