Configuring OSPF

Each switch that is configured to run OSPF must have a unique router ID. Extreme Networks
recommends that you manually set the router ID of the switches participating in OSPF, instead of
having the switch automatically choose its router ID based on the highest interface IP address. Not
performing this configuration in larger, dynamic environments could result in an older LSDB remaining
in use.

Configuring OSPF Wait Interval

ExtremeWare XOS 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, use 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>}

OSPF Wait Interval Parameters

You can configure the following parameters:
Retransmit interval—The length of time that the router waits before retransmitting an LSA that is not
●
acknowledged. If you set an interval that is too short, unnecessary retransmissions result. The
default value is 5 seconds.
Transit delay—The length of time it takes to transmit an LSA packet over the interface. The transit
●
delay must be greater than 0.
Hello interval—The interval at which routers send hello packets. Shorter times allow routers to
●
discover each other more quickly but also increase network traffic. The default value is 10 seconds.
