12.1.2 What You Need to Know

The following terms and concepts may help as you read this chapter.
Policy Routing
Traditionally, routing is based on the destination address only and the NXC takes
the shortest path to forward a packet. IP Policy Routing (IPPR) provides a
mechanism to override the default routing behavior and alter the packet
forwarding based on the policy defined by the network administrator. Policy-based
routing is applied to incoming packets on a per interface basis, prior to the normal
routing.
How You Can Use Policy Routing
• Source-Based Routing – Network administrators can use policy-based routing to
direct traffic from different users through different connections.
• Bandwidth Shaping – You can allocate bandwidth to traffic that matches routing
policies and prioritize traffic (however the application patrol's bandwidth
management is more flexible and recommended for TCP and UDP traffic). You
can also use policy routes to manage other types of traffic (like ICMP traffic).
Note: Bandwidth management in policy routes has priority over application patrol
bandwidth management.
