Bridged Mode WanLink with Virtual Ports and Redirect Devices

Goal: Setup a Bridged Mode WanLink using RDDs (Redirect Devices).

In this test scenario, a LANforge-ICE WanLink is created in Bridged Mode using Redirect Devices to illustrate an example of how to send LANforge-FIRE traffic to yourself through LANforge-ICE. This is useful when physical ports are in short supply and a proof-of-concept test is needed. NOTE: THIS WILL NOT WORK PROPERLY WITHOUT THE INSTALLATION OF THE CANDELA KERNEL.
 
  1. Setup a Netsmith Connection.
    1. Go to the Status tab and click Netsmith screenshot
    2. Right-click inside the Netsmith window and select New Connection screenshot
    3. Accept defaults, Auto Create everything and click OK screenshot
      1. NOTE: The new connection consists of two pairs of Redirect Devices, Port 1A, 1B and Port 2A, 2B and a WanLink. The new connection is not created until you click the Apply button in the Netsmith window.
    4. Apply the new connection screenshot
      1. NOTE: The new connection is created and has a Bridged Mode WanLink between Redirect Device ports 1B and 2B which are shown as smaller, green squares (B-Ports) connected by a vertical bar (WanLink).

    For more information see LANforge-GUI User Guide: Virtual Interfaces

  2. Setup the WanLink.
    1. Right-click the WanLink and select Modify WanLink screenshot
    2. Verify that the B-side ports of the Redirect Device pairs (rddVR0b and rddVR1b) are configured screenshot
      1. NOTE: Be sure to set the impairment, if any, and transfer rate
      2. Click OK when done
    3. Right-click on the WanLink and select Toggle WanLink to Running (green) screenshot

    For more information see LANforge-GUI User Guide: WanLinks (ICE)

  3. Setup the ports.
    1. Right-click port rddVR0 and select Modify Port screenshot
    2. Assign an IP address and Network Mask to rddVR0 screenshot
    3. Right-click port rddVR1 and select Modify Port screenshot
    4. Assign an IP address and Network Mask to rddVR1 screenshot
      1. NOTE: As an alternate method to set Network Mask, enter a / followed by the number of mask bits after the IP address. In this case, /24 is equivalent to 255.255.255.0
    5. Select the IPv4s checkbox at the bottom of the Netsmith window to verify port configuration screenshot
    6. Go to the Port Mgr tab to verify port configuration screenshot
      1. NOTE: The Bridged Mode WanLink is connected between rddVR0b and rddVR1b which both have 0.0.0.0 IP addresses

    For more information see LANforge-GUI User Guide: Ports (Interfaces)

  4. Create a Layer-3 Connection.
    1. Go to the Layer-3 tab and click Create screenshot
    2. The RDD-FIRE connection will use the A-side ports of the Redirect Device pairs screenshot
      1. NOTE: These are the ports rddVR0 and rddVR1 that were assigned IP addresses in step 2
    3. Verify the Layer-3 connection was created screenshot

    For more information see LANforge-GUI User Guide: Layer-3 Cross Connects (FIRE)

  5. Run LANforge-FIRE to yourself through LANforge-ICE!
    1. Select the Layer-3 Cross Connect and click Start screenshot
    2. Click Display to show the Layer-3 Cross Connect details screenshot
    3. Go to the Status tab and click Netsmith to view the graphical representation of the setup screenshot
    4. Right-click on the WanLink and select Display WanLink to display the WanLink details screenshot
