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.
Invalid Destination 
Address The number of OSPFv3 packets discarded because the packet's 
destination IP address is not the address of the ingress interface and is 
not the AllDrRouters or 
AllSpfRouters multicast address.
No Neighbor at Source Address The number of OSPFv3 packets dropped because the sender is not an 
existing neighbor or the sender's IP address does not match the 
previously recorded IP address for that neighbor
.

Type The number of OSPFv3 packets discarded because the packet type 
field in the OSPFv3 header is not a known type.
