OSPF's DR/BDR election on a broadcast segment is a filter, a max(), and a tie-break — read it as three lines of Python instead of a bullet list.

OSPF's neighbor state machine reads as two separate gates in code: Hello-phase booleans decide Init/2-Way/ExStart, and database-exchange inputs decide Loading/Full.

Reading OSPF's Hello check as code: the five fields that must match before a neighbor relationship can even begin, and why seeing your own router ID changes everything.

Fourteen sessions of BGP logic collapse into one small Python object: six pieces of state, three methods, and one three-line rhythm repeated in each of them.
