Bosses ask ospf calculate out direction of how to determine the total cost

CodePudding user response:

Spending there is a formula, cost=reference bandwidth/actual bandwidth, the default reference bandwidth is 100 m, when computing a small digital, only is rounded, if less than 1. The cost will take 1
And then put all way to route the addition of the overhead of the interface can
More reliable forward optimal path than RIP, but if the reference is 100 m cannot distinguish between gigabit bandwidth or Wan Zhao card, suggested that if a link with way of multiple front-end ports, take the largest bandwidth interface for reference network card interface reference - bandwidth 1000 m is modified to gigabit bandwidth

Big thanks,,, to understand it
