Milan Zapletal submitted the source code for a huge lab topology they built with netlab. It has almost 50 routers and over 50 Linux nodes to emulate end-users and servers.
They used netlab to configure VLANs, VRFs, IS-IS, OSPF, EIGRP, BGP, MPLS, VXLAN, and EVPN. Imagine how long it would take to configure all that by hand using a more traditional labbing tool.
The lab uses devices from three different vendors, and some of those devices are known resource hogs. Consequently, they needed a server with 128GB of RAM and 32 CPU cores, and it still took 30 minutes to start the lab -- they had to start the routers in batches of eight to avoid timeouts due to CPU overloads.
