手动安全性关联
示例：配置手动 SA
此示例说明如何使用手册安全关联 （SA） 创建 IPsec 隧道，包含以下部分：
要求
此示例使用以下硬件和软件组件：
四台安装有多服务接口的 M Series、MX 系列 或 T Series 路由器。
Junos OS 9.4 及更高版本。
在配置此功能之前，不需要除设备初始化之外的特殊配置。
概述和拓扑
安全关联 （SA） 是一种单工连接，使两台主机能够通过 IPsec 安全地相互通信。SA 有两种类型：手册 SA 和动态 SA。此示例介绍了手册 SA 配置。
手动 SA 不需要协商;所有值（包括键）都是静态的，并在配置中指定。手动 SA 使用静态定义的安全参数索引 （SPI） 值、算法和密钥，并且需要在隧道的两端进行匹配的配置。每个对等方必须具有相同的配置选项才能进行通信。
手动 SA 最适合密钥分配、维护和跟踪难度不大的小型静态网络。
拓扑结构
图 1 显示了包含一组四台路由器的 IPsec 拓扑：路由器 1、2、3 和 4。
图 1：手动 SA 拓扑
路由器 2 和 3 使用多服务 PIC 和手册 SA 设置建立 IPsec 隧道。路由器 1 和 4 提供基本连接，用于验证 IPsec 隧道是否正常运行。
配置
此示例使用四台路由器，涉及以下配置：
路由器 1 和 4 分别配置为与路由器 2 和 3 建立基本 OSPF 连接。
路由器 2 和 3 分别配置为与路由器 1 和 4 进行 OSPF 连接。路由器 2 和 3 还配置为使用手册 SA 在这两台路由器之间创建 IPsec 隧道。要通过多服务接口将流量引导至 IPsec 隧道，请在路由器 2 和 3 上配置下一跃点样式的服务集，并将配置为 IPsec 内部接口的多服务接口添加到相应路由器上的 OSPF 配置中。
注意：
此示例中显示的接口类型仅供参考。例如，您可以使用 so- 接口代替 ge- sp- ms-和 。

配置路由器 1
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路由器 1 的 [edit] 层级的 CLI 中。
set interfaces ge-1/0/1 description "to R2 ge-1/0/1" set interfaces ge-1/0/1 unit 0 family inet address 10.1.12.1/30 set interfaces lo0 unit 0 family inet address 10.0.0.1/32 set protocols ospf area 0.0.0.0 interface ge-1/0/1.0 set protocols ospf area 0.0.0.0 interface lo0.0 set routing-options router-id 10.0.0.1
分步程序
下面的示例要求您在各个配置层级中进行导航。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 1 以便与路由器 2 建立 OSPF 连接：
配置以太网接口和环路接口。
[edit interfaces] user@router1# set ge-1/0/1 description "to R2 ge-1/0/1" user@router1# set ge-1/0/1 unit 0 family inet address 10.1.12.1/30 user@router1# set lo0 unit 0 family inet address 10.0.0.1/32
指定 OSPF 区域，并将接口与 OSPF 区域相关联。
[edit protocols] user@router1# set ospf area 0.0.0.0 interface ge-1/0/1.0 user@router1# set ospf area 0.0.0.0 interface lo0.0
配置路由器 ID。
[edit routing-options] user@router1# set router-id 10.0.0.1
