Table 162. Advanced OSPFv3 Interface Statistics
Field Description
OSPFv3 Area ID The OSPFv3 area to which the selected router interface belongs. An
OSPFv3 area ID is a 32-bit integer in dotted-decimal format that
uniquely identifies the area to which the interface connects.
Area Border Router Count The total number of area border routers reachable within this area. This
is initially zero, and is calculated in each SPF pass.
AS Border Router Count The total number of autonomous system border routers reachable
within this area. This is initially zero, and is calculated in each SPF
pass.
Area LSA Count The total number of link state advertisements in this area's link state
database, excluding AS External LSAs.
IPv6 Address The IPv6 address of the interface.
Interface Events The number of times the specified OSPFv3 interface changed its state,
or an error occurred.
Virtual Events The number of state changes or errors that occurred on this virtual link.
Neighbor Events The number of times this neighbor relationship changed state, or an
error occurred.
Sent Packets The number of OSPFv3 packets transmitted on the interface.
Received Packets The number of valid OSPFv3 packets received on the interface.
Discards The number of received OSPFv3 packets discarded because of an
error in the packet or an error in processing the packet.
Bad Version The number of received OSPFv3 packets whose version field in the
OSPFv3 header does not match the version of the OSPFv3 process
handling the packet.
Virtual Link Not Found The number of received OSPFv3 packets discarded where the ingress
interface is in a non-backbone area and the OSPFv3 header identifies
the packet as belonging to the backbone, but OSPFv3 does not have a
virtual link to the packet's sender.
Area Mismatch The number of OSPFv3 packets discarded because the area ID in the
OSPFv3 header is not the area ID configured on the ingress interface.
