Description
The OSPF area to which the selected router interface belongs. An
OSPF area ID is a 32 bit integer in dotted-decimal format that uniquely
identifies the area to which the interface connects.
The total number of area border routers reachable within this area. This
is initially zero, and is calculated in each SPF pass.
The total number of autonomous system border routers reachable
within this area. This is initially zero, and is calculated in each SPF
pass.
The total number of link state advertisements in this area's link state
database, excluding AS external LSAs.
The IP address of the interface.
The number of times the specified OSPF interface changed its state, or
an error occurred.
The number of state changes or errors that occurred on this virtual link.
The number of times this neighbor relationship changed state, or an
error occurred.
The number of OSPF packets transmitted on the interface.
The number of valid OSPF packets received on the interface.
The number of received OSPF packets discarded because of an error
in the packet or an error in processing the packet.
The number of received OSPF packets whose version field in the
OSPF header does not match the version of the OSPF process
handling the packet.
The number of received packets discarded because the source IP
address is not within a subnet configured on a local interface.
The number of received OSPF packets discarded where the ingress
interface is in a non-backbone area and the OSPF header identifies the
packet as belonging to the backbone, but OSPF does not have a virtual
link to the packet's sender.
The number of OSPF packets discarded because the area ID in the
OSPF header is not the area ID configured on the ingress interface.
