Chapter 10: IP Policy-Based Forwarding Configuration Guide

Applying an IP Policy to an Interface

After you define the IP policy, it must be applied to an inbound IP interface. Once the IP
policy is applied to the interface, packets start being forwarded according to the IP policy.
To apply an IP policy to an interface, enter one of the following commands in Configure
mode:
Apply a defined IP policy to
an IP interface.
Apply a defined IP policy to
all IP interfaces on the IA.

Applying an IP Policy to Locally Generated Packets

You can apply an IP policy to locally generated packets (that is, packets generated by the
IA). To do this, enter the following command in Configure mode:
Cause packets generated by the
IA to be forwarded according to
an IP policy.

IP Policy Configuration Examples

This section presents some examples of IP policy configurations. The following uses of IP
policies are demonstrated:
•

Routing traffic to different ISPs

• Prioritizing service to customers
• Authenticating users through a firewall
• Firewall load balancing
Routing Traffic to Different ISPs
Sites that have multiple Internet service providers can create IP policies that cause
different user groups to use different ISPs. You can also create IP policies to select service
providers based on various traffic types.
