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.
