OSPF Status
Vir Interface Events—The number of state changes or error events on this virtual link.
Vir Interface Status—Displays the validity or invalidity of the entry. Setting it to 'invalid' has the effect
of rendering it inoperative.
Neighbor
The Neighbor tab displays two areas: Neighbor and Virtual Neighbor.
Neighbor
Neighbor IP Address—The IP address of this Neighbor.
Addressless Interface—Differentiates the addressless interfaces from the addressed interfaces. When the
value is set to zero, it signifies that the interface has an IP address.
Neighbor Router ID—Unique identifier of the neighboring router in the Autonomous System.
Neighbor Options—A bit mask corresponding to the neighbor's options field. When the value is set to
0, it indicates that the area accepts and operates on external information. If the values is zero, it signifies
a stub area. When the value is set to 1, it indicates that the system operates on the type of service metrics
other than TOS 0. If the value is zero, the neighbor ignores all the metrics except the TOS 0 metric.
Neighbor Priority—Signifies the priority of this neighbor in the designated router. When the value is set
to 0, it signifies that the neighbor is not eligible to become the designated router on this particular
network.
Neighbor State—The state of the relationship with this Neighbor.
Neighbor Events—The number of times this neighbor relationship has changed state, or an error has
occurred.
Neighbor LS Retransmit Q Len—The current length of the retransmission queue.
NBMA Neighbor Status—Displays the validity or invalidity of the entry. Setting it to 'invalid' has the
effect of rendering it inoperative.
Virtual Neighbor
Vir Nbr Area—The identifier of the Transit Area.
Vir Nbr Router ID—An integer that uniquely identifies the neighboring router in the Autonomous
System.
Vir Nbr IPAddr—The IP address that is used by this Virtual Neighbor.
Vir Nbr Options—A bit map corresponding to the neighbor's options field. Thus, Bit 1, if set, indicates
that the neighbor supports Type of Service Routing; if zero, no metrics other than TOS 0 are in use by
the neighbor.
Vir Nbr State—The state of the Virtual Neighbor Relationship.
Vir Nbr Events—The number of times this virtual link has changed its state, or an error has occurred.
Vir Nbr LS Retransmit Q Len—The current length of the retransmission queue.
