Modifying the Router Dead Interval

If a router does not receive a hello packet from a neighbor within a fixed amount of time, the router modifies its topological database to indicate that the neighbor is nonoperational. The time that the router waits is called the router dead interval. By default, this interval is 40 seconds (four times the default hello interval).

To modify the router dead interval, include the dead-interval statement. This interval must be the same for all routers on a shared network.
