Simple application of multipoint bidirectional republication and routing strategy

The problem is as follows

 

First , Configure ip, except AR1 All other routers have a loopback , In the picture, I have marked ,IP After configuration rip and ospf Announcement of , Here's the picture

  because AR2 The loopback of is in RIP, therefore OSPF There is only one announcement , and AR4 It happens to be with AR2 contrary , Pictured

 

AR3 and AR1 Almost the same , Just declare two paragraphs OSPF And a loopback .

then , Need to be in AR2 and AR4 Establish multi-point two-way republishing , Because there are too many logs , I will write the instructions to you

[AR2]rip

[AR2]version 2

[AR2]import-route ospf 1

[AR2]q

[AR2]ospf 1

 [AR2]area 0

[AR2]import-route rip 1

[AR2]q

This operation is in AR4 We should also carry out

Finally, the rest is AR2,4 Just go to the ,  Route planning , There are loopback interfaces type Remember to change it to brodcast

AR4 The specific operations are as follows

1. Grab the flow first

 2. More so 172.16.0.0 Segment requirements ,cost perhaps type

AR4 After the last ,AR2 Just copy it once , because brodcast Change of , So there will be no duplicate routes , This is the end of the experiment
