Description
This command configures the time, in seconds, that OSPF waits before declaring a neighbor router
down. If no hello packets are received from a neighbor for the duration of the dead interval, the router
is assumed to be down. The minimum interval must be two times the hello interval.
The no form of the command reverts to the default value.
Default
40
