OSPF Broadcast & P2P: What is the default "Dead Timer"?

A) 20 seconds
B) 40 seconds
C) 60 seconds
D) 80 seconds

Answer 1

The default Dead Timer for OSPF in both Broadcast and Point-to-Point networks is 40 seconds, which is four times the default Hello interval of 10 seconds.

Step-by-step explanation:

The default Dead Timer for OSPF (Open Shortest Path First) in both Broadcast and Point-to-Point (P2P) networks is four times the Hello interval, which is by default 10 seconds. Therefore, the correct default Dead Timer is 40 seconds (Option B). The Dead Timer is essentially a countdown that determines how long a router will wait without hearing from a neighbor before declaring that neighbor is down. In the OSPF protocol, keeping accurate timers is crucial for maintaining a reliable and accurate routing table within a network domain.
