ExtremeXOS allows you to configure the OSPF wait interval, rather than using the router dead interval.
Caution
Do not configure OSPF timers unless you are comfortable exceeding OSPF specifications. Non-standard settings may not be reliable under all circumstances.To specify the timer intervals, enter the following commands:
configure ospf area area-identifier timer retransmit-interval transit-delay hello-interval dead-interval {wait-timer-interval}
configure ospf virtual-link router-identifier area-identifier timer retransmit-interval transit-delay hello-interval dead-interval
configure ospf vlan [vlan-name | all] timer retransmit-interval transit-delay hello-interval dead-interval {wait-timer-interval}
