1182 OSPFv3 Commands
ABR Status Shows whether the router is an OSPF Area Border Router.
ASBR Status Indicates whether the router is an autonomous system border
router. Router automatically becomes an ASBR when it is
configured to redistribute routes learned from another protocol.
The possible values for the ASBR status is enabled (if the router
is configured to re-distribute routes learned by other protocols)
or disabled (if the router is not configured for the same).
Stub Router OSPF enters stub router mode, as described in RFC 3137, when
it encounters a resource limitation that prevents it from
computing a complete routing table. In this state, OSPF sets the
link metrics of non-stub links in its own router LSAs to the
largest possible value, discouraging other routers from
computing paths through the stub router, but allowing other
routers to compute routes to destinations attached to the stub
router. To restore OSPF to normal operation, resolve the
condition that caused the resource overload, then disable and re-
enable OSPF globally.
External LSDB
Overflow
OSPF enters this state when the number of external LSAs
exceeds a configured limit, as described in RFC 1765.

determined to be new instantiations.
LSA Count The number of LSAs in the link state database.
Maximum Number
of LSAs
The limit on the number of LSAs that the router can store in its

database since OSPF began operation.
