Every node creates is own map of the network
Each node "telling the world about its neighbours."
the only information passed between the neighbours is connectivity related
LSA Link State Advertisement
Contains: The node producing the LSA
Its directly connected routes
A Sequence number
Sent to every node on the network
Each node independently calculate the Short path to each network
