Which statement about a non-zero value for the load metric (k2) for EIGRP is true?

  • 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.

Suggested Answer: D. A change in the load on an interface will cause EIGRP to recalculate and update the administrative distance for all routes learned on that interface. 🗳️
Explanation -
The load metric (k2) represents the worst load on a link between source and destination.
EIGRP routing updates are triggered only by a change in network topology (like links, interfaces go up/down, router added/removed), and not by change in interface load or reliability.
The load is a five minute exponentially weighted average that is updated every five seconds (not five minutes) .
EIGRP considers the load of an interface only when sending an update for some other reason (like a link failure)
