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.
In the sample configuration in Figure 20, the policy router is configured to divide traffic
originating within the corporate network between different ISPs (100.1.1.1 and 200.1.1.1).
Figure 20. Using an IP Policy to Route Traffic to Two Different ISPs
HTTP traffic originating from network 10.50.0.0 for destination 207.31.0.0/16 is
forwarded to 100.1.1.1. Non-HTTP traffic originating from network 10.50.0.0 for
destination 207.31.0.0/16 is forwarded to 200.1.1.1. All other traffic is forwarded to
100.1.1.1.
