Helpful Hints about INE’s virtual lab environment:

• Save your configuration changes frequently in the event that you get locked out of a device or lose connectivity
• If you are suddenly logged out of the GNS3 lab environment and log back in again, you may see the prompt, “Another GNS3 instance is running, continue? (Y/N)”. Select “Yes”

• If you ever lose console access to one (or more) of your devices you will need to reboot the Ubuntu Virtual Machine that is hosting your GNS3 lab environment. To do this,

  • Minimize your GNS3 window
  • Open the “Terminal” app within the Ubuntu device

  

  • Type “reboot” within the Terminal window
  • Wait 20-30 seconds and then click the “Reconnect” option to log back in.

Lab Notes:

1. On all IOS devices (routers and switches) load the preconfiguration file from flash: memory titled, “Lab-3-Begin”.

2. Once you perform the step above the following will be preconfigured for you:

   • All IPv4 addressing on devices other than PCs as shown in the IPv4 addressing chart
   • Telnet will be preconfigured on R1 and R2
   • VLANs and 802.1q VLAN Trunks
   • Router interfaces will be administratively up.
   • Devices will have pre-configured Enable passwords of “cisco”

If you get stuck at any point during this lab and wish to view the Lab Solution, load the pre-configuration file (on any IOS device) named, “Lab-3-Solution” from flash memory.

Solution

Lab solutions are stored as viewable (and loadable) named configuration files stored in Flash memory on each device. To view the Lab Solution, login to any IOS device in your topology (Routers or Switches) and issue the following command:

    Router>enable
    Router#more flash:Lab-3-Solution
    !
    version 15.9
    service timestamps debug datetime msec
    service timestamps log datetime msec
    no service password-encryption
    !
    hostname R1
    !
    boot-start-marker
    [SNIP]

To Load** the solution configuration onto your device follow the procedure below. Please NOTE that **this procedure will completely erase your current configuration file and overwrite it with the solution configuration file:

    Router-1#configure replace flash:Lab-3-Solution
    This will apply all necessary additions and deletions
    to replace the current running configuration with the
    contents of the specified configuration file, which is
    assumed to be a complete configuration, not a partial
    configuration. Enter Y if you are sure you want to proceed. ? [no]: yes
