[r12-LoopBack1]ip add 172.16.176.1 20

此时测试一下是否互通

二：先实现公网全达（在ar3和ar5和ar6和ar7上配置缺省路由）

AR3、AR5、AR6、AR7配置缺省

# AR3

# AR7
[r7]ip route-static 0.0.0.0 0 47.0.0.2 

测试一下是否互通 

三：做MGRE

# AR3上：
[r3]int t 0/0/0
[r3-Tunnel0/0/0]ip add 172.16.0.1 29
[r3-Tunnel0/0/0]tunnel-protocol gre p2mp 
[r3-Tunnel0/0/0]source 34.0.0.1
[r3-Tunnel0/0/0]nhrp network-id 100
[r3-Tunnel0/0/0]nhrp entry multicast dynamic 

# AR5
[r5]int t 0/0/0
[r5-Tunnel0/0/0]ip add 172.16.0.2 29
[r5-Tunnel0/0/0]tunnel-protocol gre p2mp 
[r5-Tunnel0/0/0]source Serial 4/0/0
[r5-Tunnel0/0/0]nhrp network-id 100
[r5-Tunnel0/0/0]nhrp entry 172.16.0.1 34.0.0.1 register

# AR6
[r6]int t 0/0/0
[r6-Tunnel0/0/0]ip add 172.16.0.3 29
[r6-Tunnel0/0/0]tunnel-protocol gre p2mp 
[r6-Tunnel0/0/0]source Serial 4/0/0
[r6-Tunnel0/0/0]nhrp network-id 100
[r6-Tunnel0/0/0]nhrp entry 172.16.0.1 34.0.0.1 register

# AR7
[r7]int t 0/0/0
[r7-Tunnel0/0/0]ip add 172.16.0.4 29
[r7-Tunnel0/0/0]tunnel-protocol gre p2mp 
[r7-Tunnel0/0/0]source g 0/0/0
[r7-Tunnel0/0/0]nhrp network-id 100
[r7-Tunnel0/0/0]nhrp entry 172.16.0.1 34.0.0.1 register

 测试

四：启用ospf

# AR1
[r1]ospf 1 router-id 1.1.1.1
[r1-ospf-1]a 1
[r1-ospf-1-area-0.0.0.1]network 172.16.0.0 0.0.255.255

[r2-ospf-1]a 1
[r2-ospf-1-area-0.0.0.1]network 172.16.0.0 0.0.255.255

# AR3
[r3]ospf 1 router-id 3.3.3.3
[r3-ospf-1]a 1
[r3-ospf-1-area-0.0.0.1]network 172.16.32.0 0.0.0.255

[r3-ospf-1]area 0
[r3-ospf-1-area-0.0.0.0]network 172.16.0.1 0.0.0.0

[r3]int t 0/0/0
[r3-Tunnel0/0/0]ospf network-type p2mp

# AR5
[r5]ospf 1 router-id 5.5.5.5
[r5-ospf-1]area 0
[r5-ospf-1-area-0.0.0.0]network 172.16.0.0 0.0.255.255

[r5]int t 0/0/0
[r5-Tunnel0/0/0]ospf network-type p2mp

# AR6
[r6]ospf 1 router-id 6.6.6.6
[r6-ospf-1]area 0
[r6-ospf-1-area-0.0.0.0]network 172.16.0.0 0.0.0.255

[r6]int  t 0/0/0
[r6-Tunnel0/0/0]ospf network-type p2mp

[r6]ospf 1 
[r6-ospf-1]a 2
[r6-ospf-1-area-0.0.0.2]network 172.16.64.1 0.0.0.0

# AR7
[r7]ospf 1 router-id 7.7.7.7
[r7-ospf-1]area 0
[r7-ospf-1-area-0.0.0.0]network 172.16.0.0 0.0.0.255

[r7]int t 0/0/0
[r7-Tunnel0/0/0]ospf network-type  p2mp

[r7]ospf 1 
[r7-ospf-1]a 3
[r7-ospf-1-area-0.0.0.3]network 172.16.96.1 0.0.0.0

# AR8
[r8]ospf 1 router-id 8.8.8.8
[r8-ospf-1]a 3
[r8-ospf-1-area-0.0.0.3]network 172.16.96.0 0.0.0.255

# AR9
[r9]ospf 1 router-id 9.9.9.9
[r9-ospf-1]a 3
[r9-ospf-1-area-0.0.0.3]network 172.16.96.10 0.0.0.0

[r9-ospf-1]a 4
[r9-ospf-1-area-0.0.0.4]network 172.16.128.0 0.0.0.255

# AR10
[r10]ospf 1 router-id 10.10.10.10
[r10-ospf-1]a 4
[r10-ospf-1-area-0.0.0.4]network 172.16.128.0 0.0.0.255

# AR11
[r11]ospf 1 router-id 11.11.11.11

# AR12
[r12]ospf 1 router-id 12.12.12.12
[r12-ospf-1]a 2	
[r12-ospf-1-area-0.0.0.2]network 172.16.64.10 0.0.0.0

[r12]rip 
[r12-rip-1]v 2
[r12-rip-1]network 172.16.0.0

这里的AR10是没有其他区域的路由的，我们要在AR9上做 双向重发布

# 把之前的宣告的删了
[r9]ospf 1
[r9-ospf-1]area 4
[r9-ospf-1-area-0.0.0.4]undo network 172.16.128.0 0.0.0.255

# 在新的OSPF进程中宣告
[r9]ospf 2 router-id 9.9.9.9
[r9-ospf-2]area 4
[r9-ospf-2-area-0.0.0.4]network 172.16.128.0 0.0.0.255

五：减少lsa更新量

# AR1
[r1]ospf 1 
[r1-ospf-1]area 1
[r1-ospf-1-area-0.0.0.1]stub

# AR2
[r2]ospf 1

[r3-ospf-1-area-0.0.0.1]abr-summary 172.16.32.0 255.255.224.0
[r3]ip route-static 172.16.32.0 24 NULL 0

# AR6

[r12]ip route-static 172.16.160.0 24 NULL 0

六：配置NAT

# AR3
[r3]acl 2000
[r3-acl-basic-2000]rule permit source 172.16.0.0 0.0.255.255
[r3-acl-basic-2000]int s 4/0/0
[r3-Serial4/0/0]nat outbound 2000

# AR5
[r5]acl 2000
[r5-acl-basic-2000]rule permit source 172.16.0.0 0.0.255.255
[r5-acl-basic-2000]int s 4/0/0
[r5-Serial4/0/0]nat outbound 2000

# AR6
[r6]acl 2000
[r6-acl-basic-2000]rule permit source 172.16.0.0 0.0.255.255
[r6-acl-basic-2000]int s 4/0/0
[r6-Serial4/0/0]nat outbound 2000

# AR7
[r7]acl 2000
[r7-acl-basic-2000]rule permit source 172.16.0.0 0.0.255.255
[r7-acl-basic-2000]int g 0/0/0
[r7-GigabitEthernet0/0/0]nat outbound 2000

测试
