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.
12. Use Default Passive Setting 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.

Description
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 Area Border Router if it has active
non-virtual interfaces in two or more OSPF areas.
The number of external (LS type 5) LSAs (link state
advertisements) in the link state database.
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.
The number of opaque LSAs with domain wide
flooding scope.
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.
In any given OSPF area, a router will originate
several LSAs. Each router originates a router-LSA. If
the router is also the Designated Router for any of
the area's networks, it will originate network-LSAs for
those networks. This value represents the number of
LSAs originated by this router.
The number of LSAs (link state advertisements)
received that were determined to be new
instantiations. This number does not include newer
instantiations of self-originated LSAs.
