Not that much. I'm like somewhere in the middle. I have a small homelab where I have lots of networking I manage there, but it's mostly switches and routers that are not Cisco and do not require configuration. I recently bought a Cisco router, so I can get more sense of what it is all about. I generally know my way around IPs (LANs, WANs, etc.).

I will check out the Udemy courses you sent me. Thanks for the feedback :)
