Which of the following configuration settings on a router does not influence which IPv4 route a router chooses to add to its IPv4 routing table when using OSPFv2?
- auto-cost reference-bandwidth
- delay
- bandwidth
- ip ospf cost
Explanation: SPF calculates the cost of a route as the sum of the OSPF interface costs for all outgoing interfaces in the route. The interface cost can be set directly (ip ospf cost), or IOS uses a default based on the reference bandwidth and the interface bandwidth. Of the listed answers, delay is the only setting that does not influence OSPFv2 metric calculations.
