11. Use the Default Metric field to set a default for the metric of redistributed routes. This field
displays the default metric if one has already been set, or blank if one was not configured
earlier. The valid values are 1 to 16777214. The default is 0 (unconfigure).
12. 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.
13. 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.
14. 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.
15. Use Helper Support Mode to configure how the unit will act when a neighbor performs a
warm restart. The possible values are:
• Planned — Indicates that OSPF should only help a restarting neighbor during planned
events.
• Always — Indicates that OSPF help a restarting neighbor during all planned and
unplanned warm restart events.
• Disabled — Disables OSPF from acting as a helpful neighbor.
16. Configure Helper Strict LSA Checking by selecting the Enable or Disable option. When
enabled, the unit will exit helper mode whenever the topology changes.
17. Click Apply to send the updated configuration to the switch. Configuration changes take
effect immediately.
18. Click Cancel to cancel the configuration on the screen and reset the data on the screen to
the latest value of the switch.

Field Description
ASBR Mode Reflects whether the ASBR mode is enabled or disabled. Enable implies that
the router is an autonomous system border router. Router automatically
becomes an ASBR when it is configured to redistribute routes learnt from
other protocol.
ABR Status The values of this are enabled or disabled. Enabled implies that the router is
an area border router. Disabled implies that it is not an area border router.
External LSA Count The number of external (LS type 5) link state advertisements (LSAs) in the
link state database.
External LSA Checksum The sum of the LS checksums of the external LSAs contained in the link-state
database. This sum can be used to determine if there has been a change in a
router's link state database, and to compare the link-state databases of two
routers.
