描述
显式配置邻居（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 特定于对等的选项语句来覆盖这些选项。
该neighbor语句是可以包含在配置中的语句之一，用于在路由设备上定义最小 BGP 配置。（可以用语句代替allow allneighbor语句。）
注意：
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 地址静态置备为 BGP 邻居 IP 地址。仅 LNS 订阅者支持此功能。使用增强的订户管理时，还必须在[edit dynamic-profiles profile-name interfaces interface-name unit logical-unit-number]层次结构级别配置routing-services语句。
所需权限级别
