示例：为 GRE 或 IP-IP 隧道配置 CoS
本主题提供有关如何为 GRE 或 IP-IP 隧道配置服务等级 （CoS） 的示例。
要求
配置此示例之前，不需要除设备初始化之外的特殊配置。
概述
拓扑
在图 1 中，路由器 A 充当隧道入口设备。路由器 A 和ge-1/3/0路由器 B 中的接口ge-1/0/0之间的链路为 GRE 或 IP-IP 隧道。路由器 A 会监控从接口ge-1/3/0接收的流量。通过接口ge-1/0/0，路由器 C 生成流向路由器 B 的流量。

配置路由器 A
程序
逐步过程
以下示例要求您在配置层次结构中的各个级别上导航。有关导航 CLI 的信息，请参阅 CLI 用户指南中的在配置模式下使用 CLI 编辑器。
要配置路由器 A：
配置设备接口。
[edit interfaces] user@router-A# set ge-1/0/0 unit 0 family inet address 10.80.0.2/24 user@router-A# set ge-1/0/1 unit 0 family inet filter input zf-catch-all user@router-A# set ge-1/0/1 unit 0 family inet address address 10.90.0.2/24 user@router-A# set gr-2/1/0 unit 0 tunnel source 10.11.11.11 destination 10.255.245.46 user@router-A# set gr-2/1/0 unit 0 family inet address 10.21.21.21/24 user@router-A# set ip-2/1/0 unit 0 tunnel source 10.12.12.12 destination 10.255.245.46 user@router-A# set ip-2/1/0 unit 0 family inet address 10.22.22.22/24
配置静态路由。
[edit routing-options static] user@router-A# set static route 10.1.1.1/32 next-hop gr-2/1/0.0 user@router-A# set static route 10.2.2.2/32 next-hop ip-2/1/0.0
