What is SIA (Stuck in Active) in EIGRP?
Answer Posted / jitendera sinha
When EIGRP returns a stuck in active (SIA) message, it
means that it has not received a reply to a query. EIGRP
sends a query when a route is lost and another feasible
route does not exist in the topology table. The SIA is
caused by two sequential events:
* The route reported by the SIA has gone away.
* An EIGRP neighbor (or neighbors) have not replied to
the query for that route.
When the SIA occurs, the router clears the neighbor that did
not reply to the query. When this happens, determine which
neighbor has been cleared. Keep in mind that this
router can be many hops away
