OSPFv3 Commands
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.
External LSA
Count
Shows the number of external (LS type 5) link-state
advertisements in the link-state database.
External LSA
Checksum
Shows the sum of the LS checksums of external link-state
advertisements contained in the link-state database.
New LSAs
Originated
Shows the number of link-state advertisements that have been
originated.
LSAs Received Shows the number of link-state advertisements received
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
link state database.
LSA High Water
Mark
The maximum number of LSAs that have been in the link state
database since OSPF began operation.
Retransmit List
Entries
The current number of entries on all neighbors’ retransmit lists.
Maximum Number
of Retransmit
Entries
The maximum number of entries that can be on neighbors’
retransmit lists at any given time. This is the sum for all
neighbors. When OSPF receives an LSA and cannot allocate a
new retransmit list entry, the router does not acknowledge the
LSA, expecting the sender to retransmit.
Retransmit Entries
High Water Mark
The maximum number of retransmit list entries that have been
on all neighbors’ retransmit lists at one time.
NSF Support Whether graceful restart is administratively enabled. Possible
values are Support Always, Disabled, or Planned.
