ComwareV7 FW跨VPN实例的IPSEC典型配置

组网如图：

FW1与FW2建立IPSEC，内网口g1/0/0属于VPN test1，外网口g1/0/1属于VPN test。

配置完成后，MSR1可以ping通FW2的loopback地址10.1.2.2

[H3C]ping 10.1.2.2

Ping 10.1.2.2 (10.1.2.2): 56 data bytes, press CTRL+C to break

配置关键点：

FW1配置关键点：

配置注意关键点：

1.安全策略中加VRF

2.要有路由

3.ike keychain要带VPN实例（公网侧VPNtest）

ike keychain kechain vpn-instance test

4.ike profile中要带VPN实例（remote为公网侧test，inside为内网侧test1）

ike profile profile1

 match remote identity address 202.38.160.2 255.255.255.255 vpn-instance test

 inside-vpn vpn-instance test1
