NETGEAR 8800 Chassis Switch CLI Manual dead-interval Specifies the interval after which a neighboring router is declared down due to the fact that hello packets are no longer received from the neighbor. The range is 1 - 2,147,483,647 seconds. Default • retransmit interval-Default: 5 seconds • transit delay-Default: 1 second • hello interval-Default: 10 seconds • dead interval-Default: 40 seconds Usage Guidelines In OSPFv3, all areas must be connected to a backbone area. If the connection to the backbone is lost, it can be repaired by establishing a virtual link. The smaller the hello interval, the faster topological changes will be detected, but more routing traffic will ensue. The setting of the retransmit interval should be conservative, or needless retransmissions will result. The value should be larger for serial lines and virtual links. The transmit delay value should take into account the transmission and propagation delays for the interface. Note: The wait interval is not separately configurable. It is always equal to the dead interval. Example The following command sets the timers on the virtual link to router 6.6.6.6 transiting area 0.0.0.2: configure ospfv3 virtual-link 6.6.6.6 area 0.0.0.2 timer 10 transit-delay 1 hello-interval 20 dead-interval 200 create ospfv3 area create ospfv3 {domain } area Description Creates an OSPFv3 area.
