If you run the command auto-cost reference-bandwidth 10000 on one of the router in the network, what will happen?

A. It will make 10 Gbps on all of them

B. it will make 1 Gbps on all of them

C. it will make 10 Gbps on this router only

D. it will remain the same on all links of the router








 

Suggested Answer: C

This command affects all the OSPF costs on the local router as all links are recalculated with formula: cost = reference-bandwidth (in Mbps) / interface bandwidth
Therefore, in this case the command "auto-cost reference-bandwidth 10000" allows the local router to calculate the link up to 10Gbps.
