R1模拟总部，R2 与R3模拟分部
如图配置

（1）网络中目前只有两站点， R1 和R2 。同时R2为动态获取IP地址一方，要求使用要求使用 GRE over IPSec VPN 野蛮模式，保证R1和R2 内网互通。
（2）由于公司规模的扩大，又有新的站点R3接入，同时R3为动态获取IP地址一方，使用相同的方式保证R1 和R3内网互通。
注意：这里要求总部尽量使用较少的命令完成以上配置（模板技术）

步骤：

1、  完成GRE隧道的配置

[RT1-Tunnel10]source 1.1.1.1

[RT1-Tunnel10]de 4.4.4.4

[RT1-Tunnel20]source 1.1.1.1

[RT1-Tunnel20]de 3.3.3.3

[RT4-Tunnel10]source 4.4.4.4

[RT4-Tunnel10]de 1.1.1.1

[RT3-Tunnel10]source 3.3.3.3

[RT3-Tunnel10]destination 1.1.1.1

2、  完成IKE Peer配置

[RT1-ike-peer-zb]exchange-mode aggressive

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

[RT1-ike-peer-zb]id-type name

[RT1-ike-peer-zb]remote-name fb

[RT3-ike-peer-fb]exchange-mode aggressive

[RT3-ike-peer-fb]id-type name

[RT3-ike-peer-fb]remote-name fb

[RT3-ike-peer-fb]pre-shared-key simple cisco

[RT4-ike-peer-zb]exchange-mode aggressive

[RT4-ike-peer-zb]pre-shared-key simple cisco

[RT4-ike-peer-zb]remote-address 67.61.1.1

[RT4-ike-peer-zb]remote-name zb

[RT4-ike-peer-zb]id-type name

[RT3-ike-peer-zb]pre-shared-key simple cisco

[RT3-ike-peer-zb]exchange-mode aggressive

[RT3-ike-peer-zb]id-type name

[RT3-ike-peer-zb]remote-address 67.61.1.1

[RT3-ike-peer-zb]remote-name zb

3、  配置Ipsec policy模板和ipsec policy

[RT1-ipsec-policy-template-huawei-1]ike-peer zb

[RT1-ipsec-policy-template-huawei-1]proposal 1

[RT1]ipsec policy h3c 1 isakmp template Huawei

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

[RT3-acl-adv-3000]rule permit ip source 3.3.3.3 0 de 1.1.1.1 0

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

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

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

[RT3-GigabitEthernet0/0/3]ipsec policy  h3c

[RT4-acl-adv-3000]rule permit ip source 4.4.4.4 0 de 1.1.1.1 0

[RT4-ipsec-policy-isakmp-h3c-1]security acl 3000

[RT4-ipsec-policy-isakmp-h3c-1]proposal 1

[RT4-GigabitEthernet0/0/3]ipsec policy  h3c

4、  测试

192.168.1.100 ping 172.16.1.100

 

192.168.2.100 ping 172.16.1.100

 

   RT1查看Ike sa

 

   更换RT3和RT4 地址后查看RT1上的IKE SA
