What is split horizon?

It splits the traffic when you have a large bus (horizon) physical network.

Information about a route should not be sent back in the direction from which the original update came.

It holds the regular updates from broadcasting to a downed link.

It prevents regular update messages from reinstating a route that has gone down.
