200-301 - IP Connectivity - Section 3.1

Interpret the components of the routing table and determine how a router makes a forwarding decision by default using longest prefix match, administrative distance, and routing protocol metric.

Read a routing table by its parts - routing protocol code, prefix, network mask, next hop, administrative distance, metric, and gateway of last resort - and trace which entry a destination matches. Apply the default forwarding logic: the most specific (longest) prefix match wins first, administrative distance breaks ties between sources for the same prefix, and the protocol metric breaks ties within one source.
