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 satisfies most static requirements, 
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.
