2.配置OSPF

例

[r1]ospf 100 router-id 1.1.1.1
[r1-ospf-100]area 0
[r1-ospf-100-area-0.0.0.0]network 1.1.1.1 0.0.0.0
[r1-ospf-100-area-0.0.0.0]network 192.168.1.0 0.0.0.255

3.配置NAT

例

[r3]acl 2000	
[r3-acl-basic-2000]rule permit source any	 
[r3-acl-basic-2000]qu
[r3]int g0/0/0
[r3-GigabitEthernet0/0/0]nat outbound 2000
 Info: The NAT address pool is empty 

4.解决不规则区域

111 area5 不同进程

双向重发布

[r14]ospf 110
[r14-ospf-110]import-route ospf 111

110 area4

虚电路（在边界路由ABR上）

[r7]ospf 110
[r7-ospf-110]area 2   //要穿过的中间区域
[r7-ospf-110-area-0.0.0.2]vlink-peer 11.11.11.11   //目标路由的id

[r14]ospf 110
[r14-ospf-110]area 2		
[r14-ospf-110-area-0.0.0.2]vlink-peer 7.7.7.7

100 area0

tunnel隧道

[r3]int t0/0/0
[r3-Tunnel0/0/0]ip add 192.168.2.1 24   //隧道ip地址
[r3-Tunnel0/0/0]tunnel-protocol gre		
[r3-Tunnel0/0/0]source g0/0/1   //原接口
[r3-Tunnel0/0/0]description 45.1.1.2   //目的接口

[r5]int t0/0/0
[r5-Tunnel0/0/0]ip add 192.168.2.2 24
[r5-Tunnel0/0/0]tunnel-protocol gre		
[r5-Tunnel0/0/0]source g0/0/0
[r5-Tunnel0/0/0]description 34.1.1.1

宣告隧道ip地址
