show as-path
语法
show as-path <brief | detail> <logical-system (all | logical-system-name)>
语法（EX 系列交换机）
show as-path <brief | detail>
描述
显示本地路由设备正在使用的自治系统 （AS） 路径的分布（通常通过路由表）。使用此命令可以调试 AS 路径的问题，并了解如何通过策略（通过 as-path-prepend 操作）或聚合来操作 AS 路径。
AS 路径存储在哈希表中。哈希表是快速查找的一种方法。表中的每个条目称为一个存储桶。Junos OS 计算一个哈希值，用于指示 AS 路径存储在哪个存储桶中。AS 路径分散在哈希存储桶中，因此每个存储桶中存储了可管理的 AS 路径数量。仅存储唯一的 AS 路径。重复的 AS 路径会增加引用计数，但不会增加哈希表中存储的 AS 路径的数量。
选项
| none | 显示有关本地路由设备正在使用的 AS 路径的基本信息（与简介相同）。 |
| brief | detail | （可选）显示指定的输出级别。 |
| logical-system (all | logical-system-name) | （可选）在所有逻辑系统或特定逻辑系统上执行此操作。 |

输出字段
表 1 列出了命令 show as-path 的输出字段。输出字段按其出现的大致顺序列出。
字段名称 |
字段说明 |
输出级别 |
|---|---|---|
|
AS 路径总数。 |
|
|
存储桶编号。 |
所有级别 |
|
此存储桶中的 AS 路径条目数。 |
所有级别 |
|
获知路由的 AS 路径。AS 路径末尾的字母表示路径来源，同时指示 AS 路径发起点的路由状态：
|
所有级别 |
|
独立 AS 域的数量。独立 AS 域的 AS 路径不会与其他域（包括主路由实例域）的 AS 路径和 AS 路径属性共享。 |
|
|
AS 对等方地址。 |
|
|
AS 路径的长度。 |
|
|
AS 分段描述符的长度。 |
|
|
AS 路径中存在的唯一自治系统 （AS） 的数量 |
|
|
路径引用计数。 |
