  • Part 1: Establish Connectivity to TFTP Server

  • Part 2: Transfer the Configuration File from TFTP Server

  • Part 3: Backup Configuration and IOS to TFTP Server

Background / Scenario

In this activity, you will restore a configuration from a backup and then perform a new backup. Due to an equipment failure, a new router has been put in place. Fortunately, backup configuration files have been saved to a Trivial File Transfer Protocol (TFTP) Server. You are required to restore the files from the TFTP Server to get the router back online as quickly as possible.

Instructions

Part 1: Establish Connectivity to the TFTP Server

Note: Because this is a new router, the initial configuration will be performed using a console connection to the router.

  • Click PCA, then the Desktop tab, followed by Terminal to access the RTA command line.

  • Configure and activate the Gigabit Ethernet 0/0 interface. The IP address should match the default gateway for the TFTP Server.

Router(config)# interface g0/0
Router(config-if)# ip address 172.16.1.1 255.255.255.0
Router(config-if)# no shut

  • Test connectivity to TFTP Server. Troubleshoot, if necessary.

Part 2: Transfer the Configuration File from the TFTP Server

  • From privileged EXEC mode, issue the following command:

Router# copy tftp running-config
Address or name of remote host []? 172.16.1.2
Source filename []? RTA-confg
Destination filename [running-config]? <cr>

The router should return the following:

Accessing tftp://172.16.1.2/RTA-confg...
Loading RTA-confg from 172.16.1.2: !
[OK - 785 bytes]
785 bytes copied in 0.001 secs
RTA#
%SYS-5-CONFIG_I: Configured from console by console
RTA#

  • Issue the command to display the current configuration.

Question: What changes were made?

Answer: The configuration stored on the TFTP Server was loaded into the router and the hostname of the router changed to RTA.

  • Issue the appropriate show command to display the interface status.

Question: Are all interfaces active?

Answer: No, G0/1 is administratively down.

  • Correct any issues related to interface problems and test connectivity between PCA and the TFTP server.

RTA(config)#interface gigabitEthernet 0/1
RTA(config-if)#no shutdown

Part 3: Back Up Configuration and IOS to TFTP Server

  • Change the hostname of RTA to RTA-1.

RTA(config)#hostname RTA-1

  • Save the configuration to NVRAM.

RTA-1#copy running-config startup-config 
Destination filename [startup-config]? 
Building configuration...
[OK]

  • Copy the configuration to the TFTP Server using the copy command:

RTA-1# copy running-config tftp:
Address or name of remote host []? 172.16.1.2
Destination filename [RTA-1-confg]? <cr>

  • Issue the command to display the files in flash.

RTA-1#show flash: 

System flash directory:
File  Length   Name/status
  3   33591768 c2900-universalk9-mz.SPA.151-4.M4.bin
  2   28282    sigdef-category.xml
  1   227537   sigdef-default.xml
[33847587 bytes used, 221896413 available, 255744000 total]
249856K bytes of processor board System flash (Read/Write)

  • Backup the IOS in flash to the TFTP Server using the following command:

RTA-1#copy flash tftp:
Source filename []? c2900-universalk9-mz.SPA.151-4.M4.bin
Address or name of remote host []? 172.16.1.2
Destination filename [c2900-universalk9-mz.SPA.151-4.M4.bin]? <cr>

Question: What special character repeatedly displays indicating that the IOS file is being copied to the TFTP server successfully?

Answer: The exclamation point !.

  • Open the TFTP Server and click the Services tab, select TFTP, and scroll through the list of IOS files.

Question: Has the IOS file c2900-universalk9-mz.SPA.151-4.M4.bin been copied to the TFTP Server?

Answer: Yes, the c1900-universalk9-mz.SPA.151-4.M4.bin file is listed in the files on the TFP server.
