What type of routing allows network administrators to specify additional information sources for the routing table and network model?

Policy-based routing is a method that enables network administrators to define and manage the rules governing packet forwarding based on a variety of criteria beyond traditional network address information. This approach allows for more granular control over how data packets are routed through a network by using multiple factors such as source address, destination address, type of service, and even the application type that generated the packet.

By utilizing policy-based routing, administrators can specify additional information sources that contribute to the routing decisions, allowing the network to optimize the path that data takes according to traffic characteristics, service level agreements, or other administrative policies. This flexibility is beneficial in complex network environments where traffic requirements often change and must be managed more dynamically than what static or simple dynamic routing protocols can offer.

Static routing, while straightforward, lacks the adaptability and complexity of managing different traffic patterns or criteria, relying solely on a manually-configured routing table. Dynamic routing, although responsive to network changes, generally adheres to standardized protocols without the layered decision-making capabilities of policy-based routing. Default routing serves as a catch-all for packets destined for unknown networks, which doesn’t provide the nuanced control that policy-based routing offers.

In summary, policy-based routing stands out because it grants network administrators the ability to integrate various information sources into
