-## BGP社区
-最近我们要对BGP社区进行大改，请注意相关细节的变更。
-我们定义了以下BGP社区，请按照规则使用<br>
-1.不允许导出到内核：(ASN,3,0)  （对公网和UNET均生效）<br>
-2.不允许传输到IBGP：(ASN,1,0)  （对公网和UNET均生效）<br>
-3.允许传输到EBGP：(ASN,200,0)  （对公网和UNET均生效）<br>
-3.允许传输到EBGP（流经IX）：(ASN,200,1)  （公网生效）<br>
-4.允许导出到OSPF：(UNET_ASN,301,0)  （仅对UNET生效，依赖UNET）<br>
-请注意，进入我网和经过我网的路由条目，都会《社区消消乐》，即：我会把相关BGP社区全删了。
