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 :

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
R1

R8
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 】
stay area1 Regional Configuration 【 Completely peripheral area 】
R1
R2
R3
stay area2 Regionally 【 The configuration is complete nssa】
R6
R11
R12
stay area3 Area configuration 【 Completely nssa】

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 .
