What does 'Sia Status' (Stuck in Active) indicate in EIGRP?

The 'Sia Status' or "Stuck in Active" condition in EIGRP (Enhanced Interior Gateway Routing Protocol) signifies that a router has sent out a query packet to its neighbors to gather routing information but has not received any responses within a specified time frame, typically around 3 minutes. This state suggests that the router is waiting for replies to this query but either there are no replies coming back or the queried neighbors might be down or unreachable.

When a router experiences this situation, it can lead to a potential routing loop or an incomplete topology database, which impacts the network's overall stability and performance. The lack of responses can arise due to network issues, misconfigurations, or even failure of neighboring routers, preventing proper communication and timely updates of routing information.

The other choices do not accurately reflect the meaning of 'Sia Status.' For instance, routing information updating successfully would indicate normal operation rather than a stuck status. Actively querying all neighbors aligns with a part of the EIGRP operation but does not capture the essence of being "stuck." Lastly, having all routes confirmed as reachable would imply a healthy routing environment, opposite to the implications of being in an active, stuck state.
