如图配置 两实验
R1模拟总部，R2 与R3模拟分部
实验一 
要求使用 IPSec VPN 主模式，使得总部与两分部内网可相互通讯

 

步骤：

1、  配置默认路由

[RT1]ip route-static 0.0.0.0 0 202.112.1.2

[RT2]ip route-static 0.0.0.0 0 67.61.1.2

[RT3]ip route-static 0.0.0.0 0 64.67.1.2

2、  IKE peer配置

[RT1]ike proposal 1

[RT1-ike-peer-rt2]exchange-mode main

[RT1-ike-peer-rt2]pre-shared-key simple cisco

[RT1-ike-peer-rt2]id-type ip

[RT1-ike-peer-rt2]proposal 1

[RT1-ike-peer-rt2]local-address 202.112.1.1

[RT1-ike-peer-rt2]remote-address 67.61.1.1

[RT1-ike-peer-rt3]exchange-mode main

RT1-ike-peer-rt3]pre-shared-key simple cisco

[RT1-ike-peer-rt3]local-address 202.112.1.1

[RT3-ike-peer-rt1]local-address 64.67.1.1

[RT3-ike-peer-rt1]remote-address 202.112.1.1

3、  创建安全ACL

[RT1]acl number 3001 match-order config

[RT1-acl-adv-3001]rule permit ip source 192.168.1.0 0.0.0.255 destination 192.168.2.0 0.0.0.255

[RT2]acl number 3000 match-order config

[RT2-acl-adv-3000]rule permit ip source 192.168.2.0 0.0.0.255 destination 192.168.1.0 0.0.0.255

[RT3]acl number 3000 match-order config

[RT3-acl-adv-3000]rule permit ip source 192.168.3.0 0.0.0.255 destination 192.168.1.0 0.0.0.255

[RT1-acl-adv-3002]rule permit ip source 192.168.1.0 0.0.0.255 destination 192.168.3.0 0.0.0.255

4、  创建ipsec 安全提议

[RT1]ipsec proposal rt2

[RT1]ipsec proposal rt3

[RT2]ipsec proposal rt1

[RT3]ipsec proposal rt1

5、  创建Ipsec policy

[RT1-ipsec-policy-isakmp-h3c-1]security acl 3001

[RT1-ipsec-policy-isakmp-h3c-1]proposal rt2

[RT1-ipsec-policy-isakmp-h3c-1]ike-peer rt2

[RT1-ipsec-policy-isakmp-h3c-2]security acl 3002

[RT1-ipsec-policy-isakmp-h3c-2]ike-peer rt3

[RT1-ipsec-policy-isakmp-h3c-2]proposal rt3

[RT2-ipsec-policy-isakmp-h3c-1]security acl 3000

[RT2-ipsec-policy-isakmp-h3c-1]ike-peer rt1

[RT2-ipsec-policy-isakmp-h3c-1]proposal rt1

[RT3-ipsec-policy-isakmp-h3c-1]security acl 3000

[RT3-ipsec-policy-isakmp-h3c-1]ike-peer rt1

[RT3-ipsec-policy-isakmp-h3c-1]proposal rt1

6、  接口上应用ipsec policy

[RT1-GigabitEthernet0/0/0]ipsec policy h3c

[RT2-GigabitEthernet0/0/1]ipsec policy h3c

[RT3-GigabitEthernet0/0/2]ipsec policy h3c

7、  测试

192.168.1.100 ping 192.168.2.100

 

192.168.1.100 ping 192.168.3.100

 

RT1 IKE SA查看

 

RT1 ipsec SA查看

 

实验二
要求使用 IPSec VPN 野蛮模式，使得总部与两分部内网可相互通讯 (R2 R3两分部公网接口为动态获得地址情况)

 

步骤：

1、  配置静态路由

[RT1]ip route-static 0.0.0.0 0 202.112.1.2

[RT2]ip route-static 0.0.0.0 0 67.61.1.2
