Policy-based routing (PBR) is a technique used in computer networking to direct network packets based on defined criteria beyond the standard destination-based routing. Unlike traditional routing, which forwards packets solely based on their destination address, PBR allows administrators to customize routing decisions according to various factors such as source address, type of service, protocol, or application.

Unlike traditional routing, which forwards packets solely based on their destination address, PBR allows to customize routing decisions according to various factors.
With policy-based routing, network administrators can implement specific rules or policies to dictate the path that packets should take through the network. This flexibility enables organizations to optimize traffic flow, prioritize certain types of traffic, enforce security measures, and manage network resources more efficiently.

===Configuration testing===
----
Connect end device to physical port that is assingned to different routing policy. Open cmd and run this command: '''traceroute 8.8.8.8''', three physical ports that we assigned to diffrent Vlans route to 8.8.8.8 should be dispayed using different gateways.
