The following table describes the nonconfigurable OSPF Interface Statistics data that is
displayed.
Table 134. OSPF Interface Statistics
Field Description
OSPF Area ID 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.
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.
IP Address The IP address of the interface.
Interface Events The number of times the specified OSPF 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 OSPF packets transmitted on the interface.
Received Packets The number of valid OSPF packets received on the interface.
Discards The number of received OSPF packets discarded because of an error in
the packet or an error in processing the packet.
Bad Version 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.
Source Not on Local Subnet The number of received packets discarded because the source IP address
is not within a subnet configured on a local interface.
Virtual Link Not Found 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
.
Area Mismatch The number of OSPF packets discarded because the area ID in the OSPF
header is not the area ID configured on the ingress interface.
Invalid Destination Address The number of OSPF 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 addresses.
Wrong Authentication Type The number of packets discarded because the authentication type
specified in the OSPF header does not match the authentication type
configured on the ingress interface.
