CISCO IOS XE POLICY BASED ROUTING HOW TO
The following example shows how to configure policy routing with Cisco Express Forwarding. As soon as one of these features is turned on, packetsĪre automatically subjected to policy routing in the appropriate switching path. No additional configuration tasks are required to enable policy routing with CiscoĮxpress Forwarding, distributed Cisco Express Forwarding, or NetFlow.
Policy routing can be deployed on a wide scale and on high-speed interfaces.
Cisco Express Forwarding, distributed Cisco Express Forwarding, and NetFlow NPR takes advantage of new switching services. NetFlow, which provides accounting, capacity planning, and traffic monitoring capabilities. To address maintenance problems of a demand caching scheme.ĭistributed Cisco Express Forwarding, which addresses the scalability and maintenance problems of a demand caching scheme. NetFlow policy routing leverages the following technologies:Ĭisco Express Forwarding, which looks at a Forwarding Information Base (FIB) instead of a routing table when switching packets,
The Cisco Discovery Protocol (formerly known as CDP) database. Set ip next-hop verify-availability command is not supported in distributed Cisco Express Forwarding because distributed Cisco Express Forwarding does not support NetFlow Policy Routing (NPR) is available only on Cisco platforms that support Cisco Express Forwarding.ĭistributed Forwarding Information Base (FIB)-based policy routing is available only on platforms that support distributed Navigator, go to An account on is not required.įor NetFlow policy routing to work, the following features must already be configured:Ĭisco Express Forwarding, distributed Cisco Express Forwarding, or NetFlow
