This counter tracks the total number of query-reply packets sent to all neighbors in this autonomous system, sent in response to queries this router received. This is the direct response counterpart to cEigrpQueriesRcvd; every query this router receives should eventually generate a reply, so a growing gap between received queries and sent replies over time could point to the router being slow or unable to answer, risking the querying neighbor's route going stuck-in-active. If received queries are climbing steadily but sent replies lag noticeably behind, an admin would investigate whether this router itself is under CPU load and delaying its query responses, which risks triggering stuck-in-active conditions on its neighbors.
