In the embodiment of the invention, set up between BGP equipment and bgp neighbor equipment after the bgp neighbor relation, as shown in Figure 1, the sending method of this BGP route may further comprise the steps:
In the embodiment of the invention, BGP equipment is determined the precedence information of each BGP route, and utilizes the precedence information of each BGP route, by the mode of publishing policy to bgp neighbor equipment transmission BGP route, specifically includes but not limited to following mode according to specified circuit:
Mode one:
BGP equipment determines that the precedence information of each BGP route specifically comprises: BGP equipment is enabled the Netstream(network traffics on the total interface of configuration bgp protocol) function (this Netstream function is used for carrying out traffic statistics according to message purpose IP address); Afterwards, the statistics of BGP equipment query Netstream function, obtain the statistical counting of each message purpose IP flow that mate the address, and the statistical counting of definite message purpose IP flow that mate the address is the precedence information of the corresponding BGP route in this message purpose IP address; Wherein: the statistical counting of BGP route correspondence is big more, illustrates that the priority of this BGP route is high more.
In the embodiment of the invention, in order to realize under the BGP view, to enable by configuration order row delaminate-send enable according to the function of priority issue BGP route; This function is a closed condition under the default situations, and promptly order line delaminate-send enable does not enable, and BGP equipment is according to existing procedure issue BGP route, and this process repeats no more; When under the BGP view during enable command row delaminate-send enable, the technical scheme issue BGP route that BGP equipment provides according to the embodiment of the invention, be the precedence information that BGP equipment is determined each BGP route, and preferential issue have the BGP route of high priority.
In mode one, BGP equipment need be determined the precedence information of BGP route based on the statistics of Netstream function; Therefore, when BGP equipment not enabled Netstream function (promptly not carrying out traffic statistics) according to message purpose IP address, BGP equipment needs to dispose at all earlier the interfaces enabled Netstream function of bgp protocols, and configuration Netstream function is for according to carrying out traffic statistics in message purpose IP address, thereby makes Netstream carry out traffic statistics according to message purpose IP address; Based on this, BGP equipment can be by the statistics of inquiry Netstream function, obtain the statistical counting of each message purpose IP flow that mate the address, and the statistical counting of definite message purpose IP flow that mate the address is the precedence information of the corresponding BGP route in this message purpose IP address.
