Embodiment Construction

[0040] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0041] In actual processing, the inventors of the present invention found that when the gateway device of the existing fuzzy termination networking system broadcasts and sends RA messages, it needs to traverse the termination VLAN and send RA messages, and there are meaningless VLAN traversal and RA message traversal. The situation of copying and sending the text.

[0042] In the embodiment of the present invention, the gateway device may not directly send the RA message by traversing the fuzzy termination VLAN under the fuzzy termination network, but determines the specified VLAN according to the received RS message, and broadcasts in the specified VLAN Route notification message, so as to avoid meaningless VLAN traversal, RA mes...

Abstract

Embodiments of the present invention provide a router advertise packet sending method and apparatus. The method is applied to gateway devices. The method comprises the steps of receiving a router request packet sent by a host; determining, according to the router request packet, a designated virtual local area network (VLAN) to which the host belongs; and broadcasting the router advertise packet in the designated VLAN. Through adoption of the router advertise packet sending method and apparatus, the load of the gateway device of sending the RA packets in a fuzzy termination network is reduced, so that the heavy task of sending the RA packets by the existing gateway device is relieved.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a method for sending a route notification message and a device for sending a route notification message. Background technique [0002] With the rapid development of computer network technology, the host can learn the Internet Protocol Version 6 (Internet Protocol Version 6, IPv6) gateway address in the network through the Router Advertise (RA) message sent by the gateway device, such as modifying the IPv6 parameters and automatically generate an IPv6 address according to the prefix of the RA message to realize automatic address configuration. [0003] Generally, the RA message in the IPv6 network is a notification message sent by the gateway device to the accessing host with a stateless address, and is sent by regular broadcast. When there is a new host on the network, the new host usually sends a Router Solicitation (RS) message to the gateway device to trigger the ga...
