Example for Configuring TWAMP Light on an EVPN L3VPN
This section provides an example for configuring TWAMP Light functions on an EVPN L3VPN.
Networking Requirements
On the EVPN L3VPN shown in Figure 1, DeviceB functions as the Responder and DeviceA functions as the Controller.
- DeviceA: sends and receives packets over a test session, collects and calculates performance statistics, and reports the statistics to the performance management system.
- DeviceB: responds to the packets received over a test session.
Configuration Roadmap
The configuration roadmap is as follows:
- Configure an EVPN L3VPN.
- Configure the TWAMP Light Controller.
- Configure the TWAMP Light Responder.
- 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 address and UDP port number of DeviceA (Controller)
- IP Addresses: 192.168.2.2
- UDP port number: 2000
- IP address and UDP port number of DeviceB (Responder)
- IP address: 192.168.1.1
- UDP port number: 3000
- IP address and gRPC port number of the performance management system
- IP address: 192.168.100.100
- gRPC port number: 10001
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 an IS-IS SR-MPLS BE tunnel between DeviceA and DeviceB.
For the configuration roadmap, see Configuring an IS-IS SR-MPLS BE Tunnel. For configuration details, see Configuration Files.
- Configure an EVPN L3VPN between DeviceA and DeviceB.
For details about the configuration roadmap, see Configuring an EVPN to Carry Layer 3 Services. For configuration details, see Configuration Files.
- Create a TWAMP Light test session on DeviceB (Responder).
