OSPF exercise Report

One 、 The experiment purpose

Master the right MGRE Environment configuration and irregular area configuration

Two 、 Experimental content

Bold style

3、 ... and 、 The topology

The private network part is required to use 172.16.0.0/16 Divide and configure network segments . For this reason, each loopback is a network segment , The network segment connecting the router is considered to be the same network segment , Then divide .
The division is shown in the figure ：

Four 、 The experimental steps

1、 Assign the topology map as required ip And loopback

2、 Configure static default routing configuration for all routes 【 except R4, In order to enable the public network to communicate with each other 】

4、 On all devices OSPF【 except R4】

Declare the interface so that it can accept information , And divide the interface into corresponding areas according to requirements

R9 about r9 For non backbones far away from backbones, they should be republished

R10

R11

R12 Because the Huawei equipment used , I won't support it EIGRP, So use rip Instead of . At the same time R12 For non backbones far away from backbones, they should be republished

R3/5/6/7 In between is the use of Tunnel Port activated OSPF, So it needs to be modified OSPF Type of work and DR Election priority , So as to unify DR
R3 Type of work

R5 Work type and DR priority

R6 Of DR Priority work type and work type

R7 Of DR Priority work type and work type

5、 Configure the route summary of the boundary route and the configuration of the end area

Border router summary

R3【 Border router summary 】

R7【 Border router summary and complete NSSA】

R9【 Border router summary 】

R12【 Border router summary 】

5、 ... and 、 experimental result

give an example R1

6、 ... and 、 Summary of the experiment

There is no problem with the configuration at the beginning of this experiment , But the back RIP And ACL There are some problems with the configuration of . At first, I didn't think about the last air interface anti ring . Overall, the experiment , There is no problem with the basic configuration . But yes. acl Or with OSPF Relevant operations need to be strengthened .
