OSPF Cheatsheet — Cisco CCNA Routing Fundamentals

This dataset provides a detailed OSPF (Open Shortest Path First) cheatsheet created for learners preparing for the Cisco CCNA and CCNP certifications.

It summarizes the main OSPF concepts, including adjacency states, router roles (DR, BDR, ABR, ASBR), LSA types, and the process used to build and maintain routing tables in a multi-router topology.

The included materials help students and networking professionals visualize how OSPF operates and how configurations evolve across different lab environments such as Cisco Packet Tracer, EVE-NG, or GNS3.

Included materials:
• OSPF Part 1 — protocol fundamentals, router ID, LSA overview
• OSPF Part 2 — multi-router topology and configuration flow

These resources are part of the PingMyNetwork CCNA Academy, designed to make networking concepts clear, structured, and visually engaging.

Original version and additional CCNA study materials are available on PingMyNetwork – Learn Cisco Networking and Routing.
