Control Routing Information

This task describes how to control or prevent routing update exchange and propagation.
Some reasons to control or prevent routing updates are:
• To slow or stop the update traffic on a WAN link—If you do not control update traffic on an on-demand
• To prevent routing loops—If you have redundant paths or are redistributing routes into another routing
• To filter network received in updates — If you do not want other routers from learning a particular
• To prevent other routers from processing routes dynamically— If you do not want to process routing
• To preserve bandwidth—You can ensure maximum bandwidth availability for data traffic by reducing
