Computer Networking What is split horizon? Information about a route should not be sent back in the direction from which the original update came. It splits the traffic when you have a large bus (horizon) physical network. It prevents regular update messages from reinstating a route that has gone down. It holds the regular updates from broadcasting to a downed link. Information about a route should not be sent back in the direction from which the original update came.
