OSPF综合实验

实验步骤：

第一步：IP地址规划

第二步： 配置IP地址

[R12-LoopBack1]ip ad 172.16.192.1 18

第三步：测试各个路由之间能否ping通

 经过测试所有路由上的链路可以ping通

第四步：搭建MGRE环境

R3

[R3]int Tunnel 0/0/0
[R3-Tunnel0/0/0]ip ad 172.16.0.1 24  
[R3-Tunnel0/0/0]tunnel-protocol gre p2mp 

[R3-Tunnel0/0/0]source 34.0.0.3

[R3-Tunnel0/0/0]nhrp entry multicast dynamic 

 R5

[R5]interface Tunnel 0/0/0
[R5-Tunnel0/0/0]ip address 172.16.0.2 24 
[R5-Tunnel0/0/0]tunnel-protocol gre p2mp     
[R5-Tunnel0/0/0]source s4/0/0
[R5-Tunnel0/0/0]nhrp entry 172.16.0.1 34.0.0.3 register 

R6

[R6]int tu0/0/0
[R6-Tunnel0/0/0]ip ad 172.16.0.3 24
[R6-Tunnel0/0/0]tunnel-protocol gre p2mp  
[R6-Tunnel0/0/0]source s4/0/0  
[R6-Tunnel0/0/0]nhrp entry 172.16.0.1 34.0.0.3 register 

R7

[R7]interface Tunnel 0/0/0
[R7-Tunnel0/0/0]ip ad 172.16.0.4 24
[R7-Tunnel0/0/0]tunnel-protocol gre p2mp 
[R7-Tunnel0/0/0]source g 0/0/0
[R7-Tunnel0/0/0]nhrp entry 172.16.0.1 34.0.0.3 register 

第五步：配置缺省MGRE环境中路由

[R3]ip route-static 0.0.0.0 0 34.0.0.4

[R5]ip route-static 0.0.0.0 0 45.0.0.4

[R6]ip route-static 0.0.0.0 0 46.0.0.4

[R7]ip route-static 0.0.0.0 0 47.0.0.4

 在R3上ping172.16.0.2可以ping通表明搭建的隧道没有问题

第六步：配置OSPF

我们在模拟实验中多半会使用例如2.2.2.2 或3.3.3.3等等这样的id但是在真实网络中都会创建一个环回掩码32

R1

[R1]ospf 1 router-id 1.1.1.1
[R1-ospf-1]area 1
[R1-ospf-1-area-0.0.0.1]network 0.0.0.0 255.255.255.255

R2

[R2]ospf 1 router-id 2.2.2.2    
[R2-ospf-1]area 1
[R2-ospf-1-area-0.0.0.1]network 0.0.0.0 255.255.255.255

R3

[R3]ospf 1 router-id 3.3.3.3
[R3-ospf-1]area 0
[R3-ospf-1-area-0.0.0.0]network 172.16.0.1 0.0.0.0

[R3]int t0/0/0

[R3-Tunnel0/0/0]ospf network-type p2mp

[R3-Tunnel0/0/0]ospf timer hello 2

R5

[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 t0/0/0

[R5-Tunnel0/0/0]ospf network-type p2mp

[R5-Tunnel0/0/0]ospf timer hello 2

R6

[R6]ospf 1 router-id 6.6.6.6
[R6-ospf-1]area 0
[R6-ospf-1-area-0.0.0.0]network 172.16.0.3 0.0.0.0
[R6-ospf-1-area-0.0.0.0]network 172.16.2.1 0.0.0.0

[R6]int t0/0/0

[R6-Tunnel0/0/0]ospf network-type p2mp

[R6-Tunnel0/0/0]ospf timer hello 2

[R6]ospf 1
[R6-ospf-1]area 2
[R6-ospf-1-area-0.0.0.2]network 172.16.32.1 0.0.0.0

R7

[R7]ospf 1 router-id 7.7.7.7
[R7-ospf-1]area 0
[R7-ospf-1-area-0.0.0.0]network 172.16.0.4 0.0.0.0
[R7-ospf-1-area-0.0.0.0]network 172.16.3.1 0.0.0.0

[R7]int t0/0/0
[R7-Tunnel0/0/0]ospf network-type p2mp

[R7-Tunnel0/0/0]ospf timer hello 2

[R7]ospf 1  
[R7-ospf-1]a 3
[R7-ospf-1-area-0.0.0.3]network 172.16.48.1 0.0.0.0

R8

[R8]ospf 1 router-id 8.8.8.8
[R8-ospf-1]a 3
[R8-ospf-1-area-0.0.0.3]network 172.16.49.1 0.0.0.0
[R8-ospf-1-area-0.0.0.3]network 172.16.48.2 0.0.0.0

R9：需要做一个重发布不然从R3上面看学不到IP地址为40几和60几的IP地址

[R9]ospf 1 router-id 9.9.9.9
[R9-ospf-1]a 3
[R9-ospf-1-area-0.0.0.3]network 172.16.48.6 0.0.0.0

[R9]ospf 2 router-id 9.9.9.9
[R9-ospf-2]area 0
[R9-ospf-2-area-0.0.0.0]network 172.16.64.1 0.0.0.0
[R9-ospf-2-area-0.0.0.0]network 172.16.66.1 0.0.0.0

[R9]ospf 1
[R9-ospf-1]import-route ospf 2--把ospf2的导入到1上面

[R9]ospf 2
[R9-ospf-2]import-route ospf 1

R10

[R10]ospf 1 router-id 10.10.10.10   
[R10-ospf-1]area 0
[R10-ospf-1-area-0.0.0.0]network 0.0.0.0 255.255.255.255

R11

[R11]ospf 1 router-id 11.11.11.11  
[R11-ospf-1]area 2
[R11-ospf-1-area-0.0.0.2]network 0.0.0.0 255.255.255.255

R12

[R12]ospf 1 router-id 12.12.12.12  
[R12-ospf-1]area 2
[R12-ospf-1-area-0.0.0.2]network 172.16.32.6 0.0.0.0

第七步：配置RIP

[R12]rip 1
[R12-rip-1]version 2   
[R12-rip-1]network 172.16.0.0

这里做双向重发布是正常需要把ospf导入进去

[R12]rip 1
[R12-rip-1]import-route ospf 1
[R12]ospf 1 
[R12-ospf-1]import-route rip 1

第八步：进行汇总

域内汇总

[R3]ospf 1
[R3-ospf-1]area 1   
[R3-ospf-1-area-0.0.0.1]abr-summary 172.16.16.0 255.255.240.0

[R6]ospf 1
[R6-ospf-1]area 2  
[R6-ospf-1-area-0.0.0.2]abr-summary 172.16.32.0 255.255.240.0

[R7]ospf 1
[R7-ospf-1]a 3
[R7-ospf-1-area-0.0.0.3]abr-summary  172.16.48.0 255.255.240.0

域外汇总

[R9]ospf 1 
[R9-ospf-1]asbr-summary 172.16.64.0 255.255.240.0

[R12]ospf 1
[R12-ospf-1]asbr-summary 172.16.128.0 255.255.128.0

第九步：nssa

完全陌生

[R1]ospf 1 
[R1-ospf-1]a 1
[R1-ospf-1-area-0.0.0.1]st    
[R1-ospf-1-area-0.0.0.1]stub 

[R2]ospf 1
[R2-ospf-1]a    
[R2-ospf-1]a 1
[R2-ospf-1-area-0.0.0.1]st    
[R2-ospf-1-area-0.0.0.1]stub 

[R3]ospf 1 
[R3-ospf-1]a 1
[R3-ospf-1-area-0.0.0.1]stub no-summary 

[R6]ospf 1
[R6-ospf-1]a 2
[R6-ospf-1-area-0.0.0.2]nssa no-summary

[R11]ospf 1
[R11-ospf-1]a 2
[R11-ospf-1-area-0.0.0.2]nssa 

[R12]ospf 1
[R12-ospf-1]a 2
[R12-ospf-1-area-0.0.0.2]nssa 

[R7]ospf 1
[R7-ospf-1]a 3
[R7-ospf-1-area-0.0.0.3]nssa no-summary

[R8]ospf 1
[R8-ospf-1]a 3 
[R8-ospf-1-area-0.0.0.3]nssa 

[R9]ospf 1
[R9-ospf-1]a 3  
[R9-ospf-1-area-0.0.0.3]nssa 

第十步：修改认证

[R1]ospf 1
[R1-ospf-1]a 1
[R1-ospf-1-area-0.0.0.1]authentication-mode md5 1 cipher huawei

[R2]ospf 1
[R2-ospf-1]a 1
[R2-ospf-1-area-0.0.0.1]authentication-mode md5 1 cipher huawei

[R3]ospf 1
[R3-ospf-1]a 1   
[R3-ospf-1-area-0.0.0.1]authentication-mode md5 1 cipher huawei

第十一步：NAT

[R3]acl 2000
[R3-acl-basic-2000]rule permit source 172.16.0.0 0.0.255.255
[R3]int s4/0/0   
[R3-Serial4/0/0]nat outbound 2000

第十二步：测试
