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.
