Route Policies
SonicOS Enhanced provides Policy Based Routing (PBR) to to provide more flexible and granular 
traffic handling capabilities.
Policy Based Routing
A simple static routing entry specifies how to handle traffic that matches specific criteria, such as 
destination address, destination mask, gateway to forward traffic, the interface that gateway is 
located, and the route metric. This method of static routing satifies most static requirments, but is 
limited to forwarding based only on destination addressing.
Policy Based Routing (PBR) allows you to create extended static routes to provide more flexible and 
granular traffic handling capabilities. SonicOS Enhanced PBR allows for matching based upon source 
address, source netmask, destination address, destination netmask, service, interface, and metric. 
This method of routing allows for full control of forwarding based upon a large number of user defined 
variables.
A metric is a weighted cost assigned to static and dynamic routes. Metrics have a value between 0 
and 255. Lower metrics are considered better and take precedence over higher costs. SonicOS 
Enhanced adheres to Cisco defined metric values for directly connected interfaces, statically encoded 
routes, and all dynamic IP routing protocols.
