Hello Arjun

Rene primarily uses Cisco CML to create and execute lesson labs. However, you can easily use GNS3 to perform this and other QoS lesson labs.

Here are some commonly recommended router images that support extensive QoS features:

  1. Cisco IOSv
  • Image: iosv-l2-adventerprise
  • Pros: It is lightweight, supports a wide range of features including advanced QoS, and is officially supported by Cisco in GNS3.
  • Usage: Ideal for simulating various network topologies and QoS configurations.
  1. Cisco IOSvL2
  • Image: iosvl2
  • Pros: Specifically designed for Layer 2 switching with robust QoS support. It is also lightweight and efficient.
  • Usage: Best for scenarios requiring advanced Layer 2 QoS features and VLAN configurations.
  1. Cisco IOS-XE (CSR 1000v)
  • Image: csr1000v-universalk9
  • Pros: This image runs Cisco’s IOS-XE software, providing a rich set of QoS features and high performance, making it suitable for enterprise-level simulations.
  • Usage: Recommended for complex QoS configurations and high-throughput simulations.
  1. Cisco IOS (Classic)
  • Image: c3725-adventerprisek9-mz
  • Pros: Supports a comprehensive range of QoS features and is widely used in network labs for educational purposes.
  • Usage: Suitable for general QoS lab exercises and configurations.

Recommendations:

  • For simplicity and versatility: Start with iosv-l2-adventerprise or iosvl2.
  • For advanced features and enterprise-level configurations: Use csr1000v-universalk9.

Remember to take into account the legal issues involved with obtaining and using images with GNS3.

I hope this has been helpful!
