- Thread-topic: OSPF auto-cost reference-bandwidth calc
If the default reference bandwidth is 100, how does changing the auto-cost reference bandwidth to 3000 produce a cost of 10 on a directly-connected, 100 mb link?
The default cost for such a link is 1. I don't understand how multiplying the reference bandwidth by 30 produces a cost 10 times higher than the default.
This is in reference to Internetworkexpert Lab 14 Task 5.17, for those keeping score at home.
The original explanation of this command in the solutions guide doesn't explain how the results are calculated by the OSPF process.
