| OSPF
Interfaces
|
|
Interface
|
Name of the interface running OSPF.
|
|
State
|
State of the interface: BDR, Down, DR, DRother, Loop, PtToPt, or Waiting.
|
The Down state, indicating that the
interface is not functioning, and PtToPt state, indicating
that a point-to-point connection has been established, are the most
common states.
|
Area
|
Number of the area that the interface is in.
|
|
DR ID
|
Address of the area's designated device.
|
|
BDR ID
|
Address of the area's backup designated device.
|
|
Neighbors
|
Number of neighbors on this interface.
|
|
Adjacency Count
|
Number of devices in the area using the same
area identifier.
|
|
Stub Type
|
The areas into which OSPF does not flood AS
external advertisements
|
|
Passive Mode
|
In this mode the interface is present on the
network but does not transmit or receive packets.
|
|
Authentication Type
|
The authentication scheme for the backbone
or area.
|
|
Interface Address
|
The IP address of the interface.
|
|
Address Mask
|
The subnet mask or address prefix.
|
|
MTU
|
The maximum transmission unit size.
|
|
Interface Cost
|
The path cost used to calculate the root path
cost from any given LAN segment is determined by the total cost of
each link in the path.
|
|
Hello Interval
|
How often the routing device sends hello packets
out of the interface.
|
|
Dead Interval
|
The interval during which the routing device
receives no hello packets from the neighbor.
|
|
Retransmit Interval
|
The interval for which the routing device
waits to receive a link-state acknowledgment packet before retransmitting
link-state advertisements to an interface’s neighbors.

Sent
|
Displays the total number of packets sent.
|

| Details tab |
Flood Queue Depth
|
Number of entries in the extended queue.
|
|
Total Retransmits
|
Number of retransmission entries enqueued.
|
|
Total Database Summaries
|
Total number of database description packets.
|
|
| OSPF Neighbors
|
Address
|
Address of the neighbor.
|
|
Interface
|
Interface through which the neighbor is reachable.
|
|
State
|
State of the neighbor: Attempt, Down, Exchange, ExStart, Full, Init, Loading, or 2way.
|
Generally, only the Down state, indicating
a failed OSPF adjacency, and the Full state, indicating a
functional adjacency, are maintained for more than a few seconds.
The other states are transitional states that a neighbor is in only
briefly while an OSPF adjacency is being established.
|
ID
|
ID of the neighbor.
|
|
Priority
|
Priority of the neighbor to become the designated
router.
|
|
Activity Time
|
The activity time.
|
|
Area
|
Area that the neighbor is in.
|
|
Options
|
Option bits received in the hello packets
from the neighbor.
|
|
DR Address
|
Address of the designated router.
|
|
BDR Address
|
Address of the backup designated router.
|
|
Uptime
|
Length of time since the neighbor came up.
|
|
Adjacency
|
Length of time since the adjacency with the
neighbor was established.
