## AI overview

The article highlights Aleksandr Albin's nearly 20-router lab topology for practicing inter-AS IP multicast. The topology and additional configuration templates are published on GitHub, with the experience also documented in a LinkedIn post.

## Source excerpt

Aleksandr Albin built a large (almost 20-router) lab topology (based on an example from Jeff Doyle's Routing TCP/IP Volume 2) that he uses to practice inter-AS IP multicast. He also published the topology file (and additional configuration templates) on GitHub and documented his experience in a LinkedIn post.
