RIP is the oldest routing protocol in use today.
RIP is an interior gateway protocol that was created for small homogenous networks. You will see the reasoning behind it when you read more about RIP's structure in the next few sections.
RIP is a distance-vector routing protocol and, subsequently, uses the distance-vector defined path determination and routing update techniques.
Numerous RIP-like routing protocols exist—some even carry the same name—but only IP RIP is of interest to you here.
Two versions of RIP exist: RIPv1 and RIPv2. RIPv2 is an enhanced version of RIPv1. You see more about this topic later in the section, ...
