Which time interval is used by default to send EIGRP hello packets on low bandwidth interfaces?
- 1 second
- 5 seconds
- 60 seconds
- 30 seconds
Explanation: One function of the EIGRP hello packets is to ensure that EIGRP neighbors are still healthy and available. EIGRP hello packets are sent out in intervals according to the hello timer. The default EIGRP hello timer is 5 seconds on high-speed interfaces and 60 seconds on slow-speed interfaces (T1 or lower).
