RIP: distance vector — I know what my neighbors know

RIP (Routing Information Protocol) is a distance vector protocol — the oldest and simplest dynamic routing protocol. Each router only knows: 1. Its directly connected networks (metric = 1) 2. What its neighbors told it

Unlike OSPF, RIP routers never see the full topology. They just collect hop counts from neighbors and pass them along.
