Configure policy routing

Policy routing allows you to route traffic based on both source and destination IP address. Policy routing is useful when you want to configure a different route for a destination based on the source address.

To configure alternative routes to the same destination, use route metrics, ECMP, or Multi-Link routing.

In most cases, there is no need to add policy routing entries. Policy routing entries are applied before the regular routes defined in the Routing tree (overriding those configurations if matches are found). They are processed exactly in the order specified in the Policy Routing view; the first matching policy routing entry is applied to a connection and any further entries are ignored.

Policy routing entries are not automatically added to the anti-spoofing configuration, so you might need to update anti-spoofing manually.
