Distance-vector routing is consists of two parts: distance and vector. Distance is the measure of how far it is
to reach the destination and vector is the direction the packet must travel to reach that destination. The latter
is determined by the next hop of the path. Distance-vector routing protocols will learn routes from its
neighbors. This is called routing by rumor. Examples of distance-vector routing protocols are: Routing
Information Protocol (RIP), Interior Gateway Routing Protocol (IGRP), and Enhanced Interior
Gateway Routing Protocol (EIGRP).
