拓扑如下：
在这里插入图片描述

AR1的基本配置：

[AR1]int g0/0/0
[AR1-GigabitEthernet0/0/0]ip add 192.168.1.254 24
[AR1-GigabitEthernet0/0/0]undo shut
[AR1-GigabitEthernet0/0/0]quit
[AR1]int g0/0/1
[AR1-GigabitEthernet0/0/1]ip add 10.0.12.1 24
[AR1-GigabitEthernet0/0/1]undo shut

AR1的隧道配置：

[AR1]int Tunnel 0/0/0
[AR1-Tunnel0/0/0]ip add 10.0.13.1 24	
[AR1-Tunnel0/0/0]tunnel-protocol gre
[AR1-Tunnel0/0/0]source 10.0.12.1
[AR1-Tunnel0/0/0]destination 10.0.23.1

AR2的基本配置：

[AR2]int g0/0/0
[AR2-GigabitEthernet0/0/0]ip add 10.0.12.2 24
[AR2-GigabitEthernet0/0/0]undo shut
[AR2-GigabitEthernet0/0/0]quit
[AR2]int g0/0/2
[AR2-GigabitEthernet0/0/2]ip add 8.8.8.254 24
[AR2-GigabitEthernet0/0/2]undo shut
[AR2-GigabitEthernet0/0/2]quit
[AR2]int g0/0/1
[AR2-GigabitEthernet0/0/1]ip add 10.0.23.2 24
[AR2-GigabitEthernet0/0/1]undo shut

AR3的基本配置：

[AR3]int g0/0/0
[AR3-GigabitEthernet0/0/0]ip add 10.0.23.1 24
[AR3-GigabitEthernet0/0/0]undo shut
[AR3-GigabitEthernet0/0/0]quit
[AR3]int g0/0/1
[AR3-GigabitEthernet0/0/1]ip add 172.16.1.254 24
[AR3-GigabitEthernet0/0/1]undo shut

RA3的隧道配置：

[AR3]int Tunnel 0/0/0
[AR3-Tunnel0/0/0]ip add 10.0.13.3 24
[AR3-Tunnel0/0/0]tunnel-protocol gre 
[AR3-Tunnel0/0/0]source 10.0.23.1
[AR3-Tunnel0/0/0]destination 10.0.12.1

AR1中动态NAT的配置：

[AR1]acl 2000
[AR1-acl-basic-2000]rule 5 permit source 192.168.1.0 0.0.0.255
[AR1-acl-basic-2000]quit	
[AR1]nat address-group 1 10.0.12.10 10.0.12.11
[AR1]int g0/0/1
[AR1-GigabitEthernet0/0/1]nat outbound 2000 address-group 1

方法一、二随便选一个
方法一：基于静态路由让全网通

AR1的路由配置：
[AR1]ip route-static 10.0.23.0 24 10.0.12.2
[AR1]ip route-static 172.16.1.0 24 10.0.13.3
[AR1]ip route-static 8.8.8.0 24 10.0.12.2

AR2的路由配置：
[AR2]ip route-static 192.168.1.0 24 10.0.12.1

AR3的路由配置：
[AR3]ip route-static 10.0.12.0 24 10.0.23.2
[AR3]ip route-static 192.168.1.0 24 10.0.13.1

方法二：基于静态路由让全网通

AR1的路由配置：
[AR1]ip route-static 172.16.1.0 24 10.0.13.3
[AR1]ip route-static 0.0.0.0 0.0.0.0 10.0.12.2

AR2的路由配置：
[AR2]ip route-static 192.168.1.0 24 10.0.12.1

AR3的路由配置：
ip route-static 0.0.0.0 0.0.0.0 10.0.23.2
[AR3]ip route-static 192.168.1.0 24 10.0.13.1
