Traditional routing is destination-based, meaning packets are routed based on destination IP address. However, it is difficult to change the routing of specific traffic in a destination-based routing system. With Policy Based Routing (PBR), you can define routing based on criteria other than destination network—PBR lets you route traffic based on source address, source port, destination address, destination port, protocol, or a combination of these. Implementation of Policy based routing in OSPF allows sets of networks to be grouped together in an area. The topology of an area is hidden from the other Autonomous System (AS) thus reducing the routing traffic. OSPF was the first widely deployed routing protocol that could converge a network in the low seconds, and guarantee loop free paths.
