Table 139. Advanced OSPFv3 Configuration
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 learned 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 was a
change in a router's link state database, and to compare the link state
databases of two routers.
New LSAs Originated In any given OSPFv3 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 received that were determined to be new
instantiations. This number does not include newer instantiations of
self-originated LSAs.
