A network administrator is configuring the hello timer and the hold timer on an EIGRP router. What is a factor that the administrator needs to consider?

  • EIGRP hello intervals should be less than the EIGRP hold timers.
  • EIGRP hello intervals and hold timers must match between EIGRP neighbors to form an EIGRP adjacency.
  • EIGRP hold timers specify the minimum time that the router should wait to send the next hello.
  • EIGRP hello intervals specify the maximum time that the router should wait to receive the next hello.

Explanation: EIGRP hello packets are sent out in intervals according to the hello timer. EIGRP uses a second timer called the hold timer that defaults to three times the hello timer. The hold time decrements, and upon receipt of a hello packet, the hold time resets and restarts the countdown. If the hold time reaches 0, EIGRP declares the neighbor unreachable and notifies DUAL of a topology change. EIGRP neighbors can still form an adjacency if the timers do not match, but the hellos must be received before the hold time reaches zero.
