What configuration make IS-IS select optimal path based on bandwidth ?
  • You have just enabled IS-IS on the lab testing network. You notice that IS-IS is not using the optimal path selection based on the interface bandwidth. Currently, the IS-IS routing process seems to be selecting the best path based on the hop count.
    What configuration change can you make to cause IS-IS to select the optimal path based on the interface bandwidth?

    A. Change the default auto-cost reference bandwidth to a higher value.
    B. Change the interface bandwidth by using the bandwidth interface configuration mode command.
    C. Change the default IS-IS metric on each of the router interfaces to better correspond to the interface bandwidth.
    D. Enable a wide-style IS-IS metric.
    E. Enable a narrow-style IS-IS metric. 8)
