200-301 Show IP Route Output Practice Questions

Explanation: OSPF uses cost as its internal metric. By default, cost is derived primarily from bandwidth.

Explanation: When the same prefix is learned from different routing protocols, the router compares administrative distance first. EIGRP internal routes use AD 90, while OSPF uses AD 110, so the EIGRP route is preferred.

Explanation: RIP uses hop count as its metric. Lower hop count paths are preferred, up to the protocol maximum of 15 usable hops.

Explanation: If the outgoing interface or connected path to the next hop becomes unreachable, the router cannot resolve the recursive next hop and the route is removed from the table.

Explanation: The EIGRP route becomes active because the router compares administrative distance first when the same destination is learned from different routing protocols. This is one of the most common Cisco exam traps: candidates compare the OSPF metric value of 20 to the EIGRP metric value and assume the smaller number must win. That is not how route selection works across different protocols. OSPF metrics and EIGRP metrics are calculated differently, so the router does not compare them directly. Instead it checks administrative distance. EIGRP internal routes default to 90, while OSPF routes default to 110. Since 90 is lower than 110, the EIGRP route is trusted more and is installed as the active path.
