Distance Vector Routing Protocols
The meaning of Distance Vector:
A router using distance vector routing protocols knows 2 things:
Distance to final destination.
Vector, or direction, traffic should be directed.
RIP uses hop count as the metric for path selection.
If hop count for a network is greater then 15, RIP cannot supply a route to that network.
IGRP/EIGRP use Bandwidth, delay, load and reliability for path selection.
EIGRP can perform unequal cost load balancing.
EIGRP uses Diffusing Update Algorithm (DUAL) to calculate the shortest path.
EIGRP only sends updates when there is a change in the topology.
