A、A change in the load on an interface will cause EIGRP to recalculate the routing metrics and send a corresponding update out to each of its neighbors.

B、EIGRP calculates interface load as a 5 - minute exponentially weighted average that is  updated every 5 minutes.

C、EIGRP considers the load of an interface only when sending an update for some other reason.

D、A change in the load on an interface will cause EIGRP to recalculate and update the administrative distance for all routes learne d on that interface.
