13. Using IP Policy Routing

• What is IP Policy Routing (IPPR)?

Traditionally, routing is based on the destination address only and the router

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. Network administrators can use IPPR to distribute

traffic among multiple paths. For example, if a network has both the Internet

and remote node connections, we can route the Web packets to the Internet

using one policy and route the FTP packets to the remote LAN using another

policy. See the figure below.

Use IPPR to distribute traffic among multiple paths

• Benefits

Source-Based Routing - Network administrators can use policy-based

routing to direct traffic from different users through different connections.

Quality of Service (QoS) - Organizations can differentiate traffic by setting the

precedence or TOS (Type of Service) values in the IP header at the periphery

of the network to enable the backbone to prioritize traffic.
