## AI overview

This tutorial shows how to build a multi-AS netlab topology with ten routers running OSPF, IS-IS, and BGP. It uses FRRouting-based containers, node and link groups, and GitHub Codespaces to create and test the network.

## Source excerpt

A few weeks ago, Urs Baumann posted a nice example illustrating the power of netlab: a 10-router topology running OSPF, IS-IS, and BGP: He didn't post the underlying topology file, so let's create a simple topology to build something similar. Read more ...
