Policy-based routing allows administrators to route traffic along specific paths according to their needs and gives you greater flexibility in determining traffic patterns and best routes. Sometimes, simple destination-based routing is not sufficient, so in these cases you may route packets based on source address, protocol type, or application type so that they can optimally shape traffic patterns. As an administrator, understanding the collection of tools, or set of commands, that are used to manipulate the routing protocol forwarding table, and bypass the default packet forwarding, come in handy. This course explains why it is necessary to manipulate routing information in order to obtain better resiliency, performance, and availability. This course also provides an overview of these tools, configuration examples of policy-based routing, and performance issues related to path control.
