IGRP has a number of features that are designed to enhance
its stability, such as:
Holddowns
Split horizons
Poison reverse updates

HolddownsHolddowns are used to prevent regular update
messages from inappropriately reinstating a route that may
not be up.

Split horizonsSplit horizons are derived from the premise
that it is usually not useful to send information about a
route back in the direction from which it came.

Poison reverse updatesSplit horizons prevent routing loops
between adjacent routers, but poison reverse updates are
necessary to defeat larger routing loops.

Today, IGRP is showing its age, it lacks support for
variable length subnet masks (VLSM). Rather than develop an
IGRP version 2 to correct this problem, Cisco has built upon
IGRP's legacy of success with Enhanced IGRP.
