NETGEAR 8800 Chassis Switch CLI Manual Usage Guidelines Configuring OSPF timers on a per-area basis is a shorthand for applying the timers and authentication to each VLAN in the area at the time of configuration. If you add more VLANs to the area, you must configure the timers and authentication for the new VLANs explicitly. 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. • wait timer interval-This interval is required by the OSPF standard to be equal to the router dead interval. Under some circumstances, setting the wait interval to smaller values can help OSPF routers on a broadcast network to synchronize more quickly at the expense of possibly electing an incorrect DR or BDR. This value should not be set to less than the hello interval. The default value is equal to the router dead interval. Example The following command sets the timers in area 0.0.0.2: configure ospf area 0.0.0.2 timer 10 1 20 200 configure ospf ase-limit configure ospf ase-limit {timeout } Description Configures the AS-external LSA limit and overflow duration associated with OSPF database overflow handling. Syntax Description number seconds Specifies the number of external routes that can be held in a link-state database. Specifies a duration for which the system has to remain in the overflow state. Default The default for timeout is 0, which indicates that once the router goes into overflow state, it stays there until OSPF is disabled and then re-enabled. 1004 | Chapter 23. OSPF Commands
