PBR Policy Based Routing Configuration

In computer networking, policy-based routing (PBR) is a technique used to make routing decisions based on policies set by the network administrator.
When a router receives a packet it normally decides where to forward it based on the destination address in the packet, which is then used to look up an entry in a routing table. However, in some cases, there may be a need to forward the packet based on other criteria. For example, a network administrator might want to forward a packet based on the source address, not the destination address.[a] This permits routing of packets originating from different sources to different networks even when the destinations are the same and can be useful when interconnecting several private networks.
