Explanation:
Policy-based routing (PBR) provides a mechanism for expressing and implementing
forwarding/routing of data packets based on the policies defined by the network administrators. It
provides a more flexible mechanism for routing packets through routers, complementing the
existing mechanism provided by routing protocols.
Policy-based routing allows network administrators to determine and implement routing policies to
allow or deny paths based on the following:
• Identity of a particular end system
• Application
• Protocol
• Size of packets
