NETGEAR 8800 Chassis Switch CLI Manual Syntax Description domainName vlan-name tunnel-name all retransmit-interval transit-delay hello-interval dead-interval Specifies an OSPFv3 domain. OSPF-Default is the only one currently supported. Specifies an IPv6 configured VLAN. Specifies an IPv6 tunnel. Specifies all IPv6 configured VLANs or all IPv6 tunnels. Specifies the length of time that the router waits before retransmitting an LSA that is not acknowledged. The range is 1- 3,600 seconds. Specifies the length of time it takes to transmit an LSA packet over the interface. The range is 0 - 3,600 seconds. Specifies the interval at which routers send hello packets. The range is 1 65,535 seconds. 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 Use this command to configure the OSPFv3 timers on a per-interface basis. Specify the following: • retransmit interval-If you set an interval that is too short, unnecessary retransmissions will result. • transit delay-The transit delay must be greater than 0. • hello interval-Smaller times allow routers to discover each other more quickly, but also increase network traffic. • dead interval-This interval should be a multiple of the hello interval. The value of the dead interval and the hello interval must be same for all OSPFv3 routers connected to a common link. The value of the dead interval and the hello interval are advertised by OSPFv3 in Hello packets. The shorter the hello interval, the earlier topological changes will be detected, but more routing traffic will ensue. The retransmit interval must be greater than the expected round trip delay between any two routers on the attached network. The setting of this parameter must be conservative, or needless retransmission will result. Chapter 24. OSPFv3 Commands | 1055
