Routing issues can silently break connectivity—even if everything looks fine at Layer 2. In this episode, we diagnose common routing problems, including missing default routes, misconfigured static routes, and incorrectly advertised subnets. You'll learn how to use ping, traceroute, and routing tables to spot when traffic is being dropped or misrouted.

We also explore DHCP-related routing issues and IP conflicts caused by overlapping pools or rogue servers. If users can reach some destinations but not others, it’s probably a routing issue—and this episode teaches you how to spot and fix it quickly. Good routing visibility leads to fast resolutions.
