This chapter shows you how to configure policies for IP routing and static routes on your
NXC.
7.1 Policy Route
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.
7.2 Policy Route Commands
The following table identifies the values required for many of these commands. Other input
values are discussed with the corresponding commands.
