Traditionally, routing is based on the destination address only and the Switch takes the shortest path to
forward a packet. Policy routing 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 prior to the normal routing.
Individual routing policies are used as part of the overall policy routing process. A routing policy defines
the action to take when a packet meets the criteria in a specified classifier. The action is taken only
when all the criteria are met.
48.1.1 Be ne fits
• Source-Based Routing – Network administrators can use policy-based routing to direct traffic from
different users through different connections.
• Cost Savings – Policy routing allows organizations to distribute interactive traffic on high-bandwidth,
high-cost paths while using low-cost paths for batch traffic.
• Load Sharing – Network administrators can use policy routing to distribute traffic among multiple
paths.
