17. Configure the AutoCost Reference Bandwidth to control how OSPF calculates link cost.
Specify the reference bandwidth in megabits per second. Unless a link cost is configured,
the link cost is computed by dividing the reference bandwidth by the interface bandwidth.
The range is 1 to 4294967. The default is 100.
18. In the Default Passive Setting field, select Enable or Disable from the list 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. The default is Disabled.
19. Click Apply to send the updated configuration to the switch. Configuration changes take
effect immediately.
20. Click Cancel to cancel the configuration on the screen and reset the data on the screen to
the latest value of the switch.
Table 99, OSPF Configuration describes the non-configurable data that is displayed.

Field Description
ASBR Mode The router is an Autonomous System Boundary
Router if it is configured to redistribute routes from
another protocol, or if it is configured to originate an
external LSA advertising the default route.
ABR Status The router is an Autonomous System Boundary
Router if it is configured to redistribute routes from
another protocol, or if it is configured to originate an
external LSA advertising the default route.The router
is an Autonomous System Boundary Router if it is
configured to redistribute routes from another
protocol, or if it is configured to originate an external
LSA advertising the default route.
External LSA Count The number of external (LS type 5) LSAs (link state
advertisements) in the link state database.
External LSA Checksum The sum of the LS checksums of the external LSAs
(link state advertisements) 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. This value is in hexadecimal.
AS_OPAQUE LSA Count The number of opaque LSAs with domain-wide
flooding scope.
AS_OPAQUE LSA Checksum The sum of the LS checksums of the opaque LSAs
with domain wide flooding scope. 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. This value is in
hexadecimal.
