Basic Distance Vector Routing Protocol Features

EIGRP does not fit cleanly into the category of DV routing protocols or LS routing protocols. However, it most closely matches DV protocols. The next topic explains the basics of DV routing protocols as originally implemented with RIP, to give a frame of reference of how DV protocols work. In particular, the next examples show routes that use RIP’s simple hop-count metric, which, although a poor option in real networks today, is a much simpler option for learning than EIGRP’s more complex metric.

The Concept of a Distance and a Vector

The term distance vector describes what a router knows about each route. At the end of the process, when a router learns about a route to a subnet, all the router ...
