Example for Configuring TWAMP Light on an L3 VXLAN
This section provides an example for configuring TWAMP Light functions on an L3 VXLAN.
Networking Requirements
On the L3 VXLAN shown in Figure 1, DeviceA functions as the Responder and DeviceB functions as the Controller.
- DeviceA: responds to the packets received over a test session.
- DeviceB: sends and receives packets over a test session, collects and calculates performance statistics, and reports the statistics to the performance management system.
Configuration Roadmap
The configuration roadmap is as follows:
- Configure a VXLAN tunnel between DeviceA and DeviceB.
- Configure the TWAMP Light Responder on DeviceA.
- Configure the TWAMP Light Controller on DeviceB.
- Configure the Controller to send statistics to the performance management system through telemetry.
Data Preparation
To complete the configuration, you need the following data:
- IP addresses of the interfaces connecting devices
- IP addresses and UDP port numbers of the Responder and Controller. IP addresses and gPRC port numbers of the performance management system.
Procedure
- Assign IP addresses to node interfaces, including loopback interfaces.
For configuration details, see Configuration Files.
- Configure an IGP (IS-IS in this example) on the backbone network.
For configuration details, see Configuration Files.
- Configure a VXLAN tunnel between DeviceA and DeviceB.
For the configuration roadmap, see VXLAN Configuration. For configuration details, see Configuration Files.
After a VXLAN tunnel is established, you can run the display vxlan tunnel command on DeviceA to display VXLAN tunnel information. The following example uses the command output on DeviceA.

- Set the forwarding mode of the VXLAN tunnel to hardware loopback.
# Configure DeviceA.
[~DeviceA] global-gre forward-mode loopback
# Configure DeviceB.
[~DeviceB] global-gre forward-mode loopback
- Configure the TWAMP Light Responder.
