IPv6 in a Campus Network Hands - On

In this Hands-on yu will get a virtual campus LAN and through out the lab session you will configure the devices (Cisco based) in both IPv4 and IPv6. After all the configuratons you will get a virtual campus network with dual stack.

To simulate the Campus network you will use Dynagen/Dynamips.

For this hands-on we will give you a Virtual Hard Disk and Usng that you can create a virtual machine (Ubuntu 64 installed) with Dynagen/Dynamips installed. You will also find the network topology file in the VM as well.

Other than dynagen/dynamips installed VM you will get another two virtual hard disks which you can used as user PC's in two different VLANS in your virtual campus LAN.

Setting up the Virtualbox

Installation of virtualbox and Downloading virtual hard disks

  • Download and install virtualbox 5.0.x​
  • Download the Virtual Hard disks from the LEARN mirror. You can get them by following links
  • Note down the location of downloaded vdi files

Creating the VM campuslan

  • Start virtualbox and Click on New button (at top-right) to create new virtual machine
  • Enter name of the VM as campuslan
  • Select OS Type: Linux
  • Select Version: Ubuntu (64-bit)
  • Then click on Continue button
  • Set VM's memory size to 1536MB and click on Continue button
  • Set VM's hard disk option to Use an existing virtual hard disk file and click the browse button and browse to the location where you download the virtual hard disks. Then select the campuslan.vdi file and click on the create button.
  • You will see a new virtual machine named campuslan appears on Virtual Box Manager Window

Setting up Network Interfaces

  • Select the campuslan VM from left panel on Virtual box, right click and open Settings
  • Click on the Network title
  • On Adapter 1 check the Enable Network Adapter . Then change Attached to be to the Bridged Adapter and make sure the name of the interface is the same interface which you use to connect to the outside (Either Wi-Fi or Ethernet). This virtual interface will work as the WAN port of the of your virtual campus network (Can be connect from out side).
  • Click on Advanced drop down list and change the promiscuous mode to Allow All
  • On Adapter 2 check the Enable Network Adapter . Then change Attached to be to the Internal Network and give the Name of the network as VLAN10. This virtual interface will connect to a internal virtual bridged network.
  • Click on Advanced drop down list and change the promiscuous mode to Allow All
  • On Adapter 3 check the Enable Network Adapter . Then change Attached to be to the Internal Network and give the Name of the network as VLAN20. This virtual interface will connect to a internal virtual bridged network.
  • Click on Advanced drop down list and change the promiscuous mode to Allow All
  • Click OK

Creating the VM FacAPC

  • Start virtualbox and Click on New button (at top-right) to create new virtual machine
  • Enter name of the VM as FacAPC
  • Select OS Type: Linux
  • Select Version: Ubuntu (64-bit)
  • Then click on Continue button
  • Set VM's memory size to 512MB and click on Continue button
  • Set VM's hard disk option to Use an existing virtual hard disk file and click the browse button and browse to the location where you download the virtual hard disks. Then select the FacAPC.vdi file and click on the create button.
  • You will see a new virtual machine named FacAPC appears on Virtual Box Manager Window

Setting up Network Interface

  • Select the FacAPC VM from left panel on Virtual box, right click and open Settings
  • Click on the Network title
  • On Adapter 1 check the Enable Network Adapter . Then change Attached to be to the Internal Network and give the Name of the network as VLAN10. This virtual interface will connect to a internal virtual bridged network.
  • Click on Advaned drop down list and change the promiscuous mode to Allow All
  • Click OK

Creating the VM FacBPC

  • Start virtualbox and Click on New button (at top-right) to create new virtual machine
  • Enter name of the VM as FacBPC
  • Select OS Type: Linux
  • Select Version: Ubuntu (64-bit)
  • Then click on Continue button
  • Set VM's memory size to 512MB and click on Continue button
  • Set VM's hard disk option to Use an existing virtual hard disk file and click the browse button and browse to the location where you download the virtual hard disks. Then select the FacBPC.vdi file and click on the create button.
  • You will see a new virtual machine named FacBPC appears on Virtual Box Manager Window

Setting up Network Interface

  • Select the FacAPC VM from left panel on Virtual box, right click and open Settings
  • Click on the Network title
  • On Adapter 1 check the Enable Network Adapter . Then change Attached to be to the Internal Network and give the Name of the network as VLAN20. This virtual interface will connect to a internal virtual bridged network.
  • Click on Advaned drop down list and change the promiscuous mode to Allow All
  • Click OK

After Creating all three VM's. Your VM setup will look like this. https://ws.learn.ac.lk/raw-attachment/wiki/ipv6vmconf/VMSetup.jpg

Setting UP IP Addresses

campuslan VM

Before running Dynagen you have to assign IP address to the VM's network interfaces.

  • Select the campuslan VM from left panel on Virtual box, right click Start and wait till the VM starts
  • login to the machine using the following user credentials 
    usrname  : learn
password : <classpassword>
  • Then change the interfaces file. Root password is the same as class password 
    sudo vi /etc/network/interfaces
  • locate the following lines 
    iface enp0s3 inet static
 address 192.168.56.2
 netmask 255.255.255.0
 network 192.168.56.0
 broadcast 192.168.56.255
 gateway 192.168.56.1
 dns-nameservers 192.248.1.161
  • Change it to the following lines. You can find your IP Address from this table 
    iface enp0s3 inet static
 address <Your IP Address >
 netmask 255.255.255.0
 network 192.248.4.0
 broadcast 192.248.4.255
 gateway 192.248.4.254
 dns-nameservers 192.248.1.161
  • Save and Exit the editor (type :wq)
  • When you completed the IP settings , restart the Interfaces 
    sudo /etc/init.d/networking restart
  • Confirm the correct IP settings by ipconfig command. Your result should be something like the following. Check the IP address of enp0s3 Interface and see whether the other interfaces are up
