Network Engineering Training _2 Router basic configuration and iOS introduction

Lab 2: Basic Router configuration and iOS introduction. Includes: Use of the CLI with basic iOS commands, backup of profiles and backup of iOS, CDP protocol.

First, the purpose of the experiment

1. Familiar with the various modes of router CLI;

2. Familiar with the various editing commands of the router CLI;

3. Master the iOS basic commands of the router;

4. How to view the information of the router;

5. Know how to use the TFTP server

6. How to master the configuration file of the backup router

7. Learn how to back up your router's iOS.

Second, the experimental equipment and environment

Experimental hardware: Microcomputer, Cisco Real machine (including two routers, one two-layer switch, one three-tier switches)

Lab Software: Cisco Packet Tracer

Third, the experimental steps

(i) Use of the CLI and iOS basic commands

1. The experimental topology diagram is as follows:

2. Switch between user mode and privileged mode:

3. The following shows "? "and" tab "keys to use:

Under the CLI, you can directly use the "? command to get all the commands in the current mode:

You can use the "tab" key to help us automate the command:

4.IOS Edit command with history command

5. Basic iOS commands

(1) Configure Router R02 (IP is: 192.168.120.1) (120 is three digits after the number)

(2) Configure Router R03 (IP Yes : 192.168.120.2)

Click on router R02 , execute command line, ping R03 serial interface from R02 , can ping pass. As shown below:

(ii) Backup of configuration files and backup of iOS

1. The experimental topology diagram is as follows:

2. Make sure the S01 switch is factory configured, and if not, execute the following command

3. Configure the Router:

4. Configure the IP address on the PC as 172.16.120.2 255.255.255.0

5. Test connectivity

6. Back up the configuration file to the TFTP server

The "shenxiaolinfile" file can then be found on the server stating that the backup configuration file was successful on the TFTP server.

(iii) Verification actions on the real machine:

Iv. errors and analysis in the experiment

1. When backing up the configuration file to the TFTP server, the discovery cannot be backed up because the address is not configured.

The TFTP address is the physical address of the native and needs to be configured for the address.

Five, experimental experience and summary

1. The experiment was completed on time and in quantity.

2. Through this experiment I am familiar with the various modes of router CLI and various editing commands, master the router's basic iOS command;

3. I have mastered the method of viewing the information of the router, mastered the use of the TFTP server, learned the backup router's configuration file and iOS.
