示例：在分层 CoS 队列中为路由到 GRE 隧道的流量执行输出调度和整形
此示例说明如何配置通用路由封装 （GRE） 隧道设备，以对路由到 GRE 隧道的 IPv4 流量执行 CoS 输出调度和整形。运行 Junos OS 12.3R4 或更高版本、13.2R2 或更高版本、13.2R2 或更高版本的 MX 系列路由器（在 MPC1 Q、MPC2 Q 或 MPC2 EQ 模块上配置 GRE 隧道接口）支持此功能。
要求
此示例使用以下瞻博网络硬件和 Junos OS 软件：
传输网络 — 运行 Junos OS 13.3 版的 IPv4 网络。
GRE 隧道设备 — 一台 MX80 路由器安装为入口提供商边缘 （PE） 路由器。
输入和输出逻辑接口可在内置 10 千兆以太网模块化接口卡 （MIC） 的两个端口上配置：
用于接收要通过网络传输的流量的输入逻辑接口
ge-1/1/0.0。输出逻辑接口
ge-1/1/1.0、ge-1/1/1.1并ge-1/1/1.2转换为 GRE 隧道源接口gr-1/1/10.1和gr-1/1/10.2gr-1/1/10.3。有关 MX80 路由器中模块上托管的接口的信息，请参阅以下主题：
概述
在此示例中，您将路由器配置为 IPv4 流量的输入和输出逻辑接口，然后将输出逻辑接口转换为四个 GRE 隧道源接口。您还在路由表中安装静态路由，以便将输入流量路由到四个 GRE 隧道。
注意：
在向 GRE 隧道接口应用带有调度器映射和整形速率的流量控制配置文件之前，您必须在 GRE 隧道物理接口上配置并提交一个层次化调度器，以便为节点扩展指定最多两个层次计划级别。
配置
要为路由到 MX 系列路由器上 MPC1Q、MPC2Q 或 MPC2 EQ 模块上配置的 GRE 隧道接口的流量在分层 CoS 队列中配置调度和整形，请执行以下操作：
CLI 快速配置
要快速配置此示例，请复制以下命令，将其粘贴到文本文件中，删除所有换行符，更改详细信息，以便与网络配置匹配，然后将命令复制并粘贴到层级的 [edit] CLI 中。

意义
路由到设备上的 GRE 隧道的入口 IPv4 流量会受 CoS 输出调度和整形的约束。
验证 GRE 隧道接口上的调度和整形是否正常运行
目的
验证 GRE 隧道接口上的流量速率整形。
行动
在逻辑接口
gr-1/1/10.1、gr-1/1/10.2和gr-1/1/10.3上通过 GRE 隧道传输流量。要验证每个 GRE 隧道源的速率整形，请使用
show interfaces queue操作模式命令。以下示例命令输出显示了逻辑接口 gr-1/1/10.1（从源 IP 地址 10.70.1.1 到目标 IP 地址 10.70.1.3 的 GRE 隧道）的详细 CoS 队列统计信息：
user@host> show interfaces queue gr-1/1/10.1 Logical interface gr-1/1/10.1 (Index 331) (SNMP ifIndex 4045) Forwarding classes: 16 supported, 8 in use Egress queues: 8 supported, 8 in use Burst size: 0 Queue: 0, Forwarding classes: be Queued: Packets : 59613061 51294 pps Bytes : 12220677505 84125792 bps Transmitted: Packets : 2230632 3039 pps Bytes : 457279560 4985440 bps Tail-dropped packets : 4471146 2202 pps RED-dropped packets : 52911283 46053 pps Low : 49602496 46053 pps Medium-low : 0 0 pps Medium-high : 0 0 pps High : 3308787 0 pps RED-dropped bytes : 10846813015 75528000 bps Low : 10168511680 75528000 bps Medium-low : 0 0 bps Medium-high : 0 0 bps High : 678301335 0 bps Queue: 1, Forwarding classes: ef Queued: Packets : 15344874 51295 pps Bytes : 3145699170 84125760 bps Transmitted: Packets : 366115 1218 pps Bytes : 75053575 1997792 bps Tail-dropped packets : 364489 1132 pps RED-dropped packets : 14614270 48945 pps Low : 14614270 48945 pps Medium-low : 0 0 pps Medium-high : 0 0 pps High : 0 0 pps RED-dropped bytes : 2995925350 80270528 bps Low : 2995925350 80270528 bps Medium-low : 0 0 bps Medium-high : 0 0 bps High : 0 0 bps ...注意：这一步仅显示队列
0（转发类be）和队列1（转发类ef）的命令输出。
意义
现在，流量整形已连接到 GRE 隧道接口，命令输出显示，符合逻辑接口 gr-1/1/10.1（shaping-rate 8m 和 guaranteed-rate 3m）上为隧道指定的流量整形。
对于队列
0，GRE 隧道设备以 3039 pps 的速率传输流量。隧道目标设备接收的流量速率为 5，008，272 bps：3039 packets/second X 206 bytes/packet X 8 bits/byte = 5,008,272 bits/second
对于队列
0，GRE 隧道设备以 1218 pps 的速率传输流量。隧道目标设备接收的流量速率为 2，007，264 bps：1218 packets/second X 206 bytes/packet X 8 bits/byte = 2,007,264 bits/second
将这些统计数据与不进行流量整形的基准测量进行比较，如未 应用整形的测量 GRE 隧道传输速率中所述。
