Static routing!! Static routing!! Static routing!!

The above figure shows the problems to be solved , On the whole, this problem is not very difficult , The disgusting thing is that you should divide the subnets reasonably , To distribute reasonably , The most important thing is that there will be many next hops between routers , so much trouble .

The following is my subnet partition , And network segment Planning

  Then there is matching ip, with ip, with ip, Keep matching , What needs to be noted here is AR1 It's what the question says AR8, So he has three loopback interfaces , The history record has been erased , I will directly summarize , Not on display .

Pay attention to the switch after configuration 1 Of vlan2,vlan3（vlan On the network segment diagram of ）, Then there is the switch 1 and AR3 Main road , And switches 2 Mutual trunk roads , After that vlan2 and vlan3 All terminals between can be interconnected , Here's the picture

  In this way, the second half has been completed , Next is the top AR1,2,3,4, this 4 Interworking between routers , Mainly , they 4 Everyone needs to write 2 Next jump , Interworking can be realized in , And give it to the following vlan2,3 Write down the next jump , In this way, the upper and lower parts are interconnected , Here's the picture

AR2,3,4 Every router should have .

Then there is AR1,2,3 Need to have  192.168.0.192 and 192.168.192.0.224 The next hop of two network segments , also AR5 Also jump to 1,2,3, To AR1 Pay attention to add 192.168.0.16（ Loopback interface summary network segment ） The next jump

And then to AR1,2,3,4 Write it up to 192.168.0.4 The next hop of the network segment , Again ISP Also jump back to each network segment , In this way, the whole upper part will be connected , Don't forget to change AR4 in 192.168.0.224 The number of hops of the network segment is 61, Realize Gigabit disconnection , Add this condition to 100 trillion .

The whole experiment is not very difficult , The main thing is to jump a lot next , It's hard to write , A little carelessness will mess up , The following is a screenshot of the whole network reachable

Router  

  I also missed the next hop between some routers , The specific ideas are those mentioned above . Hopefully that helped .
