Monitoring OSPF Routing Information
This topic applies only to the J-Web Application package.
Use the monitoring functionality to monitor OSPF routing information on routing devices.
To view OSPF routing information in the J-Web interface, select Monitor > Routing > OSPF Information.
To view OSPF routing information in the CLI, enter the following CLI commands:
show ospf neighbor
show ospf interface
show ospf statistics
Table 94 summarizes key output fields in the OSPF routing display in the J-Web interface.
Table 94: Summary of Key OSPF Routing Output Fields
Name of the interface running OSPF.
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.
Number of the area that the interface is in.
Address of the area's designated device.
Address of the area's backup designated device.
Number of neighbors on this interface.
Number of devices in the area using the same area identifier.
The areas into which OSPF does not flood AS external advertisements
In this mode the interface is present on the network but does not transmit or receive packets.
The authentication scheme for the backbone or area.
The IP address of the interface.
The subnet mask or address prefix.
The maximum transmission unit size.
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.
How often the routing device sends hello packets out of the interface.
The interval during which the routing device receives no hello packets from the neighbor.
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.
Displays the total number of packets sent.
Displays the total number of packets received.
Flood Queue Depth
Number of entries in the extended queue.
Number of retransmission entries enqueued.
Total Database Summaries
Total number of database description packets.
Address of the neighbor.
Interface through which the neighbor is reachable.
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 of the neighbor.
Priority of the neighbor to become the designated router.
The activity time.
Area that the neighbor is in.
Option bits received in the hello packets from the neighbor.
Address of the designated router.
Address of the backup designated router.
Length of time since the neighbor came up.
Length of time since the adjacency with the neighbor was established.
