Monitoring OSPF Routing Information

To view OSPF routing information, select Monitor > Routing > OSPF Information, or enter the following CLI commands:

Note: After you make changes to the configuration in this window, you must commit the changes immediately for them to take effect. To commit all changes to the active configuration, select Commit Options > Commit. See Using the Commit Options to Commit Configuration Changes (J-Web Procedure) for details about all commit options.

Additional Information

OSPF Interfaces  

OSPF Interfaces lists the following:

  • Interface
  • State
  • Area
  • DR ID
  • BDR ID
  • Neighbors

Details Tab

Select the OSPF interface and click Details to get the following information.

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 ID

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.

 

Neighbor Count

Number of neighbors on this interface.

 

Adjacency Count

Number of devices in the area using the same area identifier.

 

Interface Type

Type of interface: LAN, NBMA, P2MP, P2P, or Virtual..

 

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.

 

Active key id

(OSPFv2 and MD5) Number from 0 to 255 that uniquely identifies an MD5 key.

 

Active key start time

(OSPFv2 and MD5) Time at which the router starts using an MD5 key to authenticate OSPF packets transmitted on the interface on which this key is configured. To authenticate received OSPF protocol packets, the key becomes effective immediately after the configuration is committed. If the start time option is not configured, the key is effective immediately for send and receive and is displayed as Start time 1970 Jan 01 00:00:00 PST.

 

LSA list

List of link-state advertisements.

 

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.

 

Poll Interval

It is applicable for nonbroadcast interfaces only and specifies how often the router sends hello packets out of the interface before it establishes adjacency with a neighbor.

 

Hello Interval

Displays how often the switch sends hello packets out of the interface.

 

Dead Interval

The interval during which the switch receives no hello packets from the neighbor.

 

Retransmit Interval

The interval for which the switch waits to receive a link-state acknowledgment packet before retransmitting link-state advertisements to an interface’s neighbors.

 
OSPF Statistics  

Packets tab

Packets Sent

Displays the total number of packets sent through the OSPF interfaces.

 

Packets Received

Click to display the total number of packets received through the OSPF interfaces.

 

Details tab displays the counter values of the following

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 switch.

 

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.
