Configuration on Clear text Authentication

Configure Clear Text Authentication on Router

Hi ! everyone on today we are going to study on how to configure on clear text authentication on routers. Which is shown in the given below in topology as screenshots. 

Step 1: Configuration on both Routers

Router0

Router1

After configuration we can see the change in state to up which appears as green color as shown in screen shot given below.

Step 2: Now we should do OSPF Routing on both Routers

Router0

Router1

Step 3: In this we have to do clear authentication on Router0 and Router1

Router0

Router1

Step 4: Finally we should verify clear text by using show command

Router0 

Router1

Finally, we have completed successfully our lab session on clear text authentication using routers. This lab is done with the Cisco Packet tracer version 7.0. 

VPN Configuration Lab using Routers

VPN Configuration using Routers

Hi ! everyone on today we are going to learn about how to configure VPN using routers. This is shown in a form of topology as screen shots given below.

Step 1: First thing is that we should assign ip address on both PCs

 Assigning on PC0

 Assigning on PC1

Step 2: Configuration process done on all the Routers

Configuration on Router1

 Configuration on Router2

Configuration on Router3 

Now we can see that the state of change to up in green color which is shown below in screenshot.

Step 3: We have to do default configuration routing method

Default configuration on Router1

 Default configuration on Router3

Step 4: Now we should check the connections by pinging on routers 

Go to Router1 and ping with Router3

Now go to Router3 and ping Router1

From the above screenshots of both the Routers pinging each other done successfully.

Step 5: After pinging we should create VPN Tunnel between Router1 & 2

First create VPN Tunnel on Router1

 Create VPN Tunnel in Router3 

Step 6: Again we have to test communication between two Routers

We should check the connection on Router1 by pinging Router3   

 Check connection in Router3 by pinging Router1

Step 7: Do the Routing for created VPN Tunnel on both the Routers

Router1

 Router3

Step 8: The next method is to Test VPN Tunnel Configuration

Testing on Router1

 Testing on Router3

Step 9: We are going to see how to trace VPN Tunnel path

Now if you want to check what path VPN tunnel is using just go to any of the computer i.e PC and then ping another PC located in different network.And then trace the path using tracert. Its result will show the path followed by VPN Tunnel created by you.

By checking in PC3 on Pinging with PC1

Therefore, we have completed our lab session in VPN configuration using routers in the cisco Packet tracer version 7.0. 

Terminal Server or Access-Server Lab

How to do Terminal Server or Access-Server with a Router 

Hi ! everyone Today we are going to learn in this tutorial about how to configure terminal server or Access-Server with a Router. But first we have to start prepare following topology given below;

It says that if a client seating on PC0 will try to login to router R1, R2,R3,R4 or R5 he/she cannot be able to access these routers directly,he/she must have to go through Router0 which is an access server.

Step 1: Now i am going to configuring Access-Server

 Step 2: After configuring Access-Server we have to do troubleshoot 

Step 3: Now again we have to go into Access-Server or Terminal server

Step 4: We should go to PC and from PC login to Access-Server or Terminal Server Router using SSH

First we have to assign the ip address for the PC0 through entering.

After completing the assigning process we have to go terminal server to check the network connections.

Now you can see that you have successfully login to Access-Server Router.

Now from Access-Server Router we will login to other router like R1,R2,R3,R4 and R5 and we can see how the process takes place.

As we said that we can look our explanation of above command will take you to Router R1. 

Step 5: When we have to logout from the Router R1 you should go to terminal router and type the below given command

Finally, we have completed our configuring Router as a Terminal server or Access-Server with the help of cisco packet tracer 7.0.
