Policy Based Routing (PBR)
Policy based routing is use to path manipulation. It is used for implementing policy that causes the packet to take a different direction. Policy based routing allows source based routing. Routing table is destination base.
In short: PBR is a technique used to make routing decisions based on policies implemented by the network administrator.
Here’s the list of some Advantages of policy based routing:-
- Different users can reach the destination from different direction
- Load sharing
- PBR will be implemented on the incoming direction of the source in interface
- If the packet is match in the route map and it is permit it will be send according to the policy
- If the packet is match in the route map and route map deny packet will be forwarded according to normal routing table
