Refer to the exhibit. A network administrator verifies on an enterprise network that EIGRP query packets are delayed because of packet loss. The administrator issues the show ip protocols | include Active command to see the EIGRP active timer on a router. What can the administrator conclude from this output?
- EIGRP waits 120 seconds before sending a SIA query to neighbors that did not respond.
- The SIA state is declared for a neighbor without receiving an SIA reply after 4 minutes.
- Upon receipt of an SIA query from a neighbor router, the router needs to respond within 60 seconds to avoid being SIA state.
- This is the default value of the active timer.
Explanation: Occasionally, an EIGRP query is delayed because of packet loss, slow neighbors, or a large hop count. EIGRP maintains an active timer, which has a default value of 3 minutes (180 seconds). According to the output, the active timer was set to 2 minutes (120 seconds). EIGRP then waits half of the active timer value that was set (60 seconds) for a reply. If the router does not receive a response within 60 seconds, the originating router sends a SIA query to EIGRP neighbors that did not respond.
