Mgre.hdlc.ppp.chap.nat comprehensive experiment

As shown in the following figure

First, divide the network segment , Here's the picture  

  After the network segment division is completed, configure the interfaces of each terminal and router ip, problem 1 Be solved , We solve it from difficult to easy , Look at the problem first 5, To build about AR1,2,3,4 Of MGRE, Then build Tunnel , I have given the tunnel network segment diagram 12.1.1.0/24, We will start to establish the central site and branch site directly , There is no doubt about it AR1 For the central site ,AR3,4 For branch sites ,AR2 We don't have to worry about , Just take it as a turning point .

Central site configuration

 

Branch site configuration

AR3

 

AR4        

 

After the end of site configuration, configure the default route , Just jump to the left AR2 The nearest port is enough , Here's the picture

AR1

 

 AR3

 AR4 Empathy

Next is the announcement of each main network segment , Here's the picture

AR1

 AR3

AR4 Empathy , Then we can come ping Check the ports between routers , Check whether the previous operation is wrong

 

  You can see , It all works , But at this time pc End sum AR2 The loopback interface of is impassable , The reason is that... Is not used NAT And call , So look at the picture below

AR1

AR4 

 

Then we can call it at the outgoing interface of each server

AR1

AR4

 

  At this time, use any terminal to pingAR2 Loopback interface ,ping Then you can go to the next step

Here we are , The last three questions are over , We just need HDLC Packaging and  PPP,CHAP Certification is enough , The process is very simple , Look at the picture below

HDLC encapsulation

PPP authentication

 

Certified

 

CHAP

Certified

 

 

Here we are , End of experiment
