Step 9
Configuring Split Horizon
Routers connected to broadcast-type IP networks and using distance-vector routing protocols normally use
the split-horizon mechanism to reduce the possibility of routing loops. Split horizon blocks information about
routes from being advertised by a router on any interface from which that information originated. This feature
can optimize communication among multiple routers, especially when links are broken.
In general, we do not recommend disabling split horizon unless you are certain that your application
requires it to properly advertise routes.
