# 2

The concept is called Split Horizon.

It is used to avoid rooting loops in a network.

Basic principle is - "Information about routing path for a
particular packet is never sent back on the interface from
which it was received".

In simple sense, we can say "DON'T TELL ME WHAT I JUST TOLD YOU"
