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.

Table 127. OSPF Configuration
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.
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 was 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 was a
change in a router's link state database, and to compare the link state
databases of two routers. This value is in hexadecimal.
New LSAs Originated In any given OSPF area, a router originates several LSAs. Each router
originates a router-LSA. If the router is also the designated router for
any of the area's networks, it originates network LSAs for those
networks. This value represents the number of LSAs originated by this
router.
LSAs Received 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.
