最佳答案
路由写了吗？
就是ip route-static 192.168.20.0 24 100.1.1.2，对端同理。没有路由的话流量不会引到g0/0口上，也就不会触发IPSEC。

您好，参考这个案例
MSR V5平台和MSR V7平台路由器IPSec VPN对接典型配置(主模式)
1 配置需求或说明
1.1 适用产品系列
本案例提到的MSR V5平台路由器是指Comware V5 软件平台MSR WiNet系列路由器，如MSR830-WiNet 、MSR 830-10-WiNet 、MSR 930-WiNet 、MSR 930-10-WiNet 、MSR 930-WiNet-W 、MSR 2600-10-WiNet等
本案例提到的MSR V7平台路由器是指Comware V7平台的MSR830-WiNet系列路由器，如MSR830-10BEI-WiNet 、MSR830-6EI-WiNet 、MSR830-5BEI-WiNet 、MSR830-6BHI-WiNet 、MSR830-10BHI-WiNet等
1.2 配置需求及实现的效果
MSR V5路由器外网口G0/1的地址为1.1.1.1（模拟运营商公网固定地址环境），MSR V7路由器外网口G0/1的地址为2.2.2.2（模拟运营商公网固定地址环境），两个路由器外网口地址之间路由可达可以互相ping通。要实现对MSR V5所在的内网（192.168.1.0/24）与MSR V7路由器所在的内网（172.16.1.0/24）之间的数据流进行安全保护，实现两端内网终端通过IPsec VPN 隧道进行互访。
2 组网图
3 配置步骤
3.1 配置路由器基本上网
#路由器基本上网配置省略，MSR V5路由器的上网具体设置步骤请参考“2.1.2 路由器外网使用固定IP地址上网配置方法”章节中“MSR830[930][2600]系列路由器基本上网（静态IP）命令行配置（V5）”案例，MSR V7路由器的上网具体设置步骤请参考“2.1.2 路由器外网使用固定IP地址上网配置方法”章节中“MSR830-WiNet系列路由器基本上网（静态IP）命令行配置（V7）”案例

第一阶段ike sa还是无法起来，开启debug ike 也没看到相关日志，就好像没任何流量一样，手动rest ike sa也试过不行
