3 Enter ROUTER OSPF mode.
CONFIGURATION mode
router ospf process-id
Process ID is the ID assigned when configuring OSPFv2 globally.
4 Configure the area as a stub area.
CONFIG-ROUTER-OSPF-id mode
area area-id stub [no-summary]
Use the keywords no-summary to prevent transmission into the area of summary ASBR LSAs.
Area ID is the number or IP address assigned when creating the area.
Example of the show ip ospf database database-summary Command
To view which LSAs are transmitted, use the show ip ospf database process-id database-summary
command in EXEC Privilege mode.
Dell#show ip ospf 34 database database-summary

To view information on areas, use the show ip ospf process-id command in EXEC Privilege mode.
Configuring LSA Throttling Timers
Configured LSA timers replace the standard transmit and acceptance times for LSAs.
The LSA throttling timers are configured in milliseconds, with the interval time increasing exponentially until a
maximum time has been reached. If the maximum time is reached, the system continues to transmit at the
max-interval. If the system is stable for twice the maximum interval time, the system reverts to the start-
interval timer and the cycle begins again.
1 Specify the interval times for all LSA transmissions.
CONFIG-ROUTEROSPF- id mode
timers throttle lsa all {start-interval | hold-interval | max-interval}
• start-interval: set the minimum interval between the initial sending and resending the same
LSA. The range is from 0 to 600,000 milliseconds.
• hold-interval: set the next interval to send the same LSA. This interval is the time between
sending the same LSA after the start-interval has been attempted. The range is from 1 to 600,000
milliseconds.
• max-interval: set the maximum amount of time the system waits before sending the LSA. The
range is from 1 to 600,000 milliseconds.
2 Specify the interval for LSA acceptance.
CONFIG-ROUTEROSPF- id mode
timers throttle lsa arrival arrival-time
