Written lessons
Build a clear understanding
Deep, structured lessons that explain the why, not just the commands. From fundamentals to the exact behavior exam day actually tests.
A complete way to learn networking
PacketGB turns scattered documentation into one connected study path for CCNA, CCNP and CCIE Enterprise. Written lessons explain the why. Labs make it stick. Flashcards prove it stuck.
The PacketGB method
Everything is arranged in a clear order, so you always know what to do next.

Written lessons
Build a clear understanding
Deep, structured lessons that explain the why, not just the commands. From fundamentals to the exact behavior exam day actually tests.
02
Study notes
Learn from real study notes
Battle-tested notes: the commands, gotchas and exam traps collected the hard way — so you don't have to.
03
Hands-on labs
Turn knowledge into experience
Knowledge becomes skill only in the lab. Configure, verify, break, fix — the precise loop the CCIE lab rewards.
04
Flashcards
Test your understanding
If you can't recall it under pressure, you don't know it yet. Flashcards expose what didn't stick — before the exam does.
Exams don't ask what OSPF is. They ask why the adjacency is down, which knob changes the path, and what breaks when you touch it. PacketGB lessons go there: real behavior, design choices, troubleshooting, with real configurations on real topologies.
