说明
显式配置邻接方（对等方）。要配置多个 BGP 对等方，请包含多个 neighbor 语句。
默认情况下，对等方的选项与组的选项相同。您可以通过在语句中包含 neighbor 对等方特定的选项语句来覆盖这些选项。
语句 neighbor 是可在配置中包含以定义路由设备上的最小 BGP 配置的语句之一。（您可以添加语句 allow all 来代替 neighbor 语句。）
注：
在配置了增强型订阅者管理的 MX 系列路由器上，您可以使用此语句将订阅者的客户端 IP 地址静态配置为 BGP 邻接方 IP 地址。仅 LNS 订阅者支持此功能。借助增强的订阅者管理，您还必须在层次结构级别配置 routing-services 语句 [edit dynamic-profiles profile-name interfaces interface-name unit logical-unit-number] 。
