Real Network Troubleshooting in Production | Introducing Corelink

Most networking videos online show perfect labs and ideal scenarios.
That’s not how real networks work.

In this video, I introduce Corelink — a channel focused on real-world network engineering and troubleshooting in live production environments.

I’ll be sharing how I approach actual network problems, including:

VLAN and switching issues

Voice & SIP troubleshooting

Firewalls and SD-WAN failures

MPLS, VRFs, and service-provider networking

Security hardening and remediation

Network planning and design

How I use AI tools like ChatGPT during troubleshooting and planning

This channel is about showing how networks really break, how engineers think through problems with incomplete information, and how issues are resolved under real-world pressure.

If you’re a network engineer, IT professional, or anyone curious about how modern networks actually work — you’re in the right place.

Subscribe to follow along as we dive into real troubleshooting, real design decisions, and real solutions.
