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

The concept of policy-based routing is crucial for network administrators as it enables them to implement routing decisions based on a set of defined policies that take into account various factors beyond just destination addresses. This type of routing allows administrators to specify additional sources of information that influence how traffic is directed through the network. For example, policies can be set based on the type of application, the source or destination IP address, or even the time of day.

In practice, policy-based routing can help optimize network performance and resource utilization by allowing traffic to be routed according to specific business requirements or performance metrics. This flexibility is particularly useful in complex networks where different types of traffic have distinct characteristics or needs.

Other routing methods, such as static routes, dynamic routing, and default routing, do not provide this level of granularity or control. Static routing involves manually defining specific routes without the ability to dynamically adapt based on network conditions. Dynamic routing uses protocols to automatically adjust the routing table based on changing network information, but it is primarily driven by the destination and does not incorporate additional policies. Default routing serves as a fallback option for traffic that does not match any specific routes but lacks the capability to enforce complex routing decisions based on custom policies.

Thus, policy-based routing stands out as the
