精品资料H3C MSR系列路由器IPsec典型配置举例(V7). 1  简介本文档介绍IPsec的典型配置举例。2  配置前提本文档适用于使用Comware V7软件版本的MSR系列路由器，如果使用过程中与产品实际情况有差异，请参考相关产品手册，或以设备实际情况为准。本文档中的配置均是在实验室环境下进行的配置和验证，配置前设备的所有参数均采用出厂时的缺省配置。如果您已经对设备进行了配置，为了保证配置效果，请确认现有配置和以下举例中的配置不冲突。本文档假设您已了解IPsec特性。3  使用iNode客户端基于证书认证的L2TP over IPsec功能配置举例3.1  组网需求如所示，PPP用户Host与Device建立L2TP隧道，Windows server 2003作为CA服务器，要求：·     通过L2TP隧道访问Corporate network。·     用IPsec对L2TP隧道进行数据加密。·     采用RSA证书认证方式建立IPsec隧道。图1 基于证书认证的L2TP over IPsec配置组网图  3.2  配置思路由于使用证书认证方式建立IPsec隧道，所以需要在ike profile中配置local-identity为dn，指定从本端证书中的主题字段取得本端身份。3.3  使用版本本举例是在R0106版本上进行配置和验证的。3.4  配置步骤3.4.1  Device的配置(1)     配置各接口IP地址# 配置接口GigabitEthernet2/0/1的IP地址。<Device> system-viewDevice interface
