动态路由之OSPF综合实验

本文主要是介绍动态路由之OSPF综合实验，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

实验内容内容及拓扑如下

整个OSPF环境IP基于172.16.0.0/16划分

 更改area0区域网络类型为p2mp，使得邻居关系成功建立

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

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

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

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

RIP区域的路由信息重发布到OSPF区域中去

[r12]ospf
[r12-ospf-1]import-route rip 1
[r12-ospf-1]q

 再使用重发布导入area 4区域的路由信息

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

减少LSA的更新量，加快收敏，保障更新安全

减少更新量（通过汇总与特殊区域实现）

 汇总，并配置空接口避免出现环路

 配置特殊区域

[R1]ospf 1

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

 下发一条缺省路由指向R9

[R9]ospf 2
[R9-ospf-2]default-route-advertise

 加快收敛（减少计时器时间）

[R3]int t 0/0/0
[R3-Tunnel0/0/0]ospf timer hello 5

[R5]int t 0/0/0
[R5-Tunnel0/0/0]ospf timer hello 5

[R6]int t 0/0/0
[R6-Tunnel0/0/0]ospf timer hello 5

[R7]int t 0/0/0
[R7-Tunnel0/0/0]ospf timer hello 5

 保障更新安全

进行手工认证，即区域认证（实际上也是接口认证）

[R1]ospf 1
[R1-ospf-1]a 1
[R1-ospf-1-area-0.0.0.1]authentication-mode md5 1 123456

[R2]ospf 1
[R2-ospf-1]a  1
[R2-ospf-1-area-0.0.0.1]authentication-mode md5 1 cipher 123456

[R3]ospf 1
[R3-ospf-1]a 1
[R3-ospf-1-area-0.0.0.1]authentication-mode md5 1 cipher 123456
