QoS - Recommended router images for QoS labs in GNS3

To perform Quality of Service (QoS) labs in GNS3, several Cisco router images are recommended due to their extensive QoS feature support:

  1. Cisco IOSv

    • Image: iosv-l2-adventerprise
    • Pros: 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.

  2. Cisco IOSvL2

    • Image: iosvl2
    • Pros: Designed for Layer 2 switching with robust QoS support. Lightweight and efficient.
    • Usage: Best for scenarios requiring advanced Layer 2 QoS features and VLAN configurations.

  3. Cisco IOS-XE (CSR 1000v)

    • Image: csr1000v-universalk9
    • Pros: Runs Cisco’s IOS-XE software, providing a rich set of QoS features and high performance, suitable for enterprise-level simulations.
    • Usage: Recommended for complex QoS configurations and high-throughput simulations.

  4. 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.

Note: Be aware of the legal issues involved with obtaining and using images with GNS3.
