Answer

Using Spirent TestCenter to Test IPv6 Transition

Spirent TestCenter allows you to configure the relevant parameters to transmit test traffic over an IPv6 transitional mechanism.
IPv6 Transition Test Setup Overview
To configure IPv6 transition mechanisms test setup parameters, in the system tree at the left of the Test Configuration window select a device or All Devices and either the 6rd/4to6 tab or the DS-Lite tab.
Setting up an IPv6 transition test
To configure an IPv6 transition test:
1.     Connect to a chassis and reserve ports.
2.     Configure the IPv6 transition mechanism to be used in the test:
a.     Configure 6rd/4to6 parameters. (see below)
b.     Configure DS-Lite parameters. (see below)
3.     Configure the desired traffic type and protocol for the test traffic.
4.     Run the test and view the results based on the test traffic type.
Example 6rd/6to4 configuration
This test requires two test ports.
  • Port 1 emulates a 6rd Customer Edge (CE) router connected to the service provider (SP) IPv4 network.
  • Port 2 emulates an IPv6 router connected on the IPv6 network side of the SP 6rd Border Relay (BR).
  • The device under test (DUT) is a 6rd BR on the edge SP IPv4 network.
To configure and run the test:
1.     On test port 1 create two devices. Configure one with IPv4 encapsulation, the other with IPv6 encapsulation. For the IPv6 device, you only need to configure the source MAC address.
·         When you create an IPv6 Transition Link in a later step, the IPv6 device uses the gateway of the IPv4 device.
·         The 64-bit network prefix of the IPv6 device is filled in automatically using the 6rd configuration of the IPv4 device.
·         The 64-bit interface ID is filled in automatically using the source MAC address of the IPv6 device.
2.     Enable 6rd on the IPv4 device and configure the parameters.
3.     Create an IPv6 Transition Link.
·         In the system tree at the left of the Test Configuration window, expand test port 1 and select Devices.
·         In the toolbar, click the Create Links button.
·         For Link Type, select IPv6 Transition Link.
·         In the device list order the devices so that the IPv4 device is first.
·         Highlight both devices with SHIFT+click.
·         Click the Cascade button.
4.     On test port 2 create one device, configure it with IPv6 encapsulation, and configure the IPv6 gateway parameters.
5.     Create a stream block for the IPv6 devices.
·         In the system tree, select All Stream Blocks.
·         Click the Add toolbar button.
·         On the Ports step, select both ports and click the Next button.
·         On the Endpoints step, set the Encapsulation filter to IPv6 and the Orientation to Bidirectional.
·         Select the CE port IPv6 device (test port 1) as the source and the v6 network IPv6 device (test port 2) as the destination.
·         Click the Add button.
·         Click the Next button.
·         Configure the remaining parameters as desired, and click the Finish button.
6.     Initiate ARP/ND on the IPv4 device on test port 1 and the IPv6 device on test port 2. Do not initiate ARP/ND on the IPv6 device on test port 1.
7.     On the toolbar, click the Start traffic on all ports button.
Example DS-Lite configuration
This test requires two test ports.
  • Port 1 emulates a DS-Lite Customer Edge (CE) B4 (Basic Bridging Broadband) router connected to the service provider (SP) IPv6 network.
  • Port 2 emulates an IPv4 router connected on the IPv4 network side of the SP DS-Lite Address Family Transition Router (AFTR).
  • The device under test (DUT) is an AFTR on the edge SP IPv6 network.
To configure and run the test:
1.     On test port 1 create two devices. Configure one with IPv6 encapsulation, the other with IPv4 encapsulation. For the IPv4 device, you only need to configure the IPv4 address.
·         When you create an IPv6 Transition Link in a later step, the IPv4 device uses the source MAC address and gateway of the IPv6 device.

Tip: The IPv6 device supports both IPv6 Autoconfiguration and Gateway Learning. To use IPv6 Autoconfiguration, start the device before initiating ARP/ND.

2.     Enable DS-Lite on the IPv6 device and configure the parameters.
3.     Create an IPv6 Transition Link.
·         In the system tree at the left of the Test Configurationwindow, expand test port 1 and select Devices.
·         In the toolbar, click the Create Links button.
·         For Link Type, select IPv6 Transition Link.
·         In the device list order the devices so that the IPv6 device is first.
·         Highlight both devices with SHIFT+click.
·         Click the Cascade button.
4.     On test port 2 create one device, configure it with IPv4 encapsulation, and configure the IPv4 parameters.
5.     Create a stream block for the IPv4 devices.
·         In the system tree, select All Stream Blocks.
·         Click the Add toolbar button.
·         On the Ports step, select both ports and click the Next button.
·         On the Endpoints step, set the Encapsulation filter to IPv4 and the Orientation to Bidirectional.
·         Select the CE port IPv4 device (test port 1) as the source and the v4 network IPv4 device (test port 2) as the destination.
·         Click the Add button.
·         Click the Next button.
·         Configure the remaining parameters as desired, and click the Finish button.
6.     Initiate ARP/ND on the IPv6 device on test port 1 and the IPv4 device on test port 2. Do not initiate ARP/ND on the IPv4 device on test port 1.

On the toolbar, click the Start traffic on all ports button.
