6.7 How to Configure Routing Policy

The Switch checks the routing table and then forwards traffic through the default gateway (R1) based on the destination address. This example shows you how to configure policy route to send traffic that matches a layer-3 classifier to a different gateway (R2) for special treatment. The layer-3 classifier groups packets marked with DSCP value 58 into a flow. Packets marked with different DSCP values, such as 13 are forwarded to the default gateway. The Switch applies policy-based routing rules to incoming packets prior to the normal routing.
