Labs¶

Get hands-on with SRv6 in your own lab environment. No expensive hardware required.

Build lightweight SRv6 topologies with Docker containers. Ideal for Linux-native SRv6 and FRR.

Build complete, preconfigured SRv6 topologies using FRRouting, Cisco IOS XE, Cisco IOS XR, or Junos containers or virtual machines.

Emulate vendor routers (IOS-XR, Junos) for realistic SRv6 testing.
