Why learn from the top 1% of engineers?
Because passing an exam and doing the job are different skills, and only experience closes the gap. Network Kings mentors have spent 11 to 20+ years building and running networks, cloud platforms and pipelines at companies like Apple, Juniper Networks, IBM and CDAC. They teach what breaks in production, why, and how engineers fix it under pressure.

Same problem, two answers. Pick a track:
On the job: Two routers' OSPF neighbours are stuck in ExStart and never reach Full.
The textbook answer
OSPF moves through Down, Init, 2-Way, ExStart, Exchange, Loading and Full. Memorise the neighbour states for the exam.
Correct. Not enough to fix it.
How a production engineer teaches it
- Suspect an MTU mismatch first. ExStart and Exchange stalls usually come down to it.
- Compare
show ip ospf interfaceon both ends and fix the interface MTU. - Use
ip ospf mtu-ignoreonly as a stopgap, and say so in the change record. - Write down why it happened, so the next engineer finds it in minutes.
