OSPF Network Types - FINALLY, an explanation that makes sense - Practical OSPF 

Every OSPF link is associated with an OSPF Network Type. There are 5 Network Types that exist: Point to Point, Broadcast, Non-Broadcast Multi-Access (NBMA), Point to Multipoint, and Point to Multipoint Non Broadcast (P2MP-NB).
Each Network Type acts slightly different in an effort to optimize OSPF's behavior. In this video, we look at the differences between all five OSPF network types.
This is lesson 13 of the Practical OSPF series. The full series is available here:
