| Dynamic routing, even in small
internetworks, can involve much more than just enabling the default
behavior of a routing protocol. A few simple commands may be enough
to get dynamic routing started, but more advanced configuration must
be done to enable such features as routing update control and
exchanges among multiple routing protocols. You can optimize routing
in a network by controlling when a router exchanges routing updates
and what those updates contain. This chapter examines the key IOS
route optimization features, including routing update control,
policy-based routing, and route redistribution.
