quote of the day, routing policies...

from jeff doyle...

routing policies: A set of rules that govern how packets are forwarded in a network or change the default packet forwarding behavior.

 Route filters work by regulating the routes that are entered into, or advertised out of, the route table. They have somewhat different effects on link-state routing protocols than they do on distance-vector routing protocols. A router running a distance-vector protocol advertises routes based on what is in its route table. As a result, a route filter will influence which routes the router advertises to its neighbors.

On the other hand, routers running link-state protocols determine their routes based on information in their link-state database, rather than the advertised route entries of their neighbors. Route filters have no effect on link- state advertisements or the link-state database
