8. 
In the Exit Overflow Interval field, specify the number of seconds that, after entering 
overflow state, the router must wait before attempting to leave overflow state. 
Because OSPFv3 cannot originate nondefault external LSAs while in overflow state, this 
allows the router to again originate nondefault AS-external-LSAs. If you enter an exit 
overflow interval of 0, the router does not leave the overflow state until it is restarted. The 
range is 0 to 2,147,483,647 seconds. The default is 0.
When the number of nondefault external LSAs exceeds a configured limit, the router 
enters an overflow state as defined in RFC 1765. 
9. 
Enter the External LSDB Limit. This is the maximum number of AS-external-LSAs that can 
be stored in the database. 
A value of –1 implies there is no limit on the number that can be saved. The valid range of 
values is –1 to 2147483647. The default is –1 (no limit).
10. 
Use the Default Metric field to set a default for the metric of redistributed routes. 
This field displays the default metric if one was already set, or blank if one was not 
configured earlier. The valid values are 1 to 16777214. The default is 0 (unconfigured).
11. 
Use the Maximum Paths field to configure the maximum number of paths that OSPFv3 can 
report to a given destination. 
The valid values are 1 to 4.
12. 
Configure the AutoCost Reference Bandwidth to control how OSPF calculates default 
metrics for the interface. 
The valid values are 1 to 4294967. The default is 100.
13. 
In the Default Passive Setting, select the Enable or Disable option to configure the global 
passive mode setting for all OSPF interfaces. 
Configuring this field overwrites any present interface-level passive mode setting. OSPF 
does not form adjacencies on passive interfaces, but does advertise attached networks 
as stub networks.
14. 
Use Helper Support Mode to configure how the unit acts when a neighbor performs a 
warm restart. 
The possible values are as follows:
Planned
. OSPF helps a restarting neighbor only during planned events.
Always
. OSPF helps a restarting neighbor during all planned and unplanned warm 
restart events.
Disabled
. OSPF does not act as a helpful neighbor.
15. 
Configure Helper Strict LSA Checking by selecting the Enable or Disable option. 
When enabled, the unit exits helper mode whenever the topology changes.
16. 
Click the Apply button.
The updated configuration is sent to the switch. Configuration changes take effect 
immediately.
