The DISPLAY TCPIP,<tcpipjobname>,OMPROUTE,OSPF,STATISTICS command displays statistics generated by the OSPF routing protocol. The statistics indicate how well the implementation is performing, including its memory and network utilization. Many of the fields displayed are confirmation of the OSPF configuration. A sample output with explanations of entries follows:
EZZ7856I OSPF STATISTICS 366
OSPF ROUTER ID: 9.167.100.13
EXTERNAL COMPARISON: TYPE 1
AS BOUNDARY CAPABILITY: NO
IMPORT EXTERNAL ROUTES: NONE
ORIG. DEFAULT ROUTE: NO
DEFAULT ROUTE COST: (1, TYPE 2)
DEFAULT FORWARD. ADDR.: 0.0.0.0

# DIJKSTRA RUNS: 25 INCREMENTAL SUMM. UPDATES: 0

The fields for this output are:
OSPF ROUTER |
ID Displays the router's OSPF router ID. |
EXTERNAL COMPARISON |
Displays the external route type used by the router when importing external routes. |
AS BOUNDARY CAPABILITY |
Displays whether external routes will be imported. |
IMPORT EXTERNAL ROUTES |
Displays the external routes that will be imported. |
ORIG. DEFAULT ROUTE |
Displays whether the router will advertise an OSPF default route. |
DEFAULT ROUTE COST |
Displays the cost and type of the default route (if advertised). |
DEFAULT FORWARD ADDR |
Displays the forwarding address specified in the default route (if advertised). |
ATTACHED AREAS |
Indicates the number of areas to which that the router has active interfaces. |
OSPF PACKETS RCVD |
Covers all types of OSPF protocol packets. |
TRANSIT NODES |
Allocated to store router links and network links advertisements. |
LS ADV |
Allocated to store summary link and AS external link advertisements. |
QUEUE HEADERS |
Form lists of link state advertisements. These lists are used in the flooding and database exchange processes; if the number of queue headers allocated is not equal to the number freed, database synchronization with a neighbor is in progress. |
MAXIMUM LSA SIZE |
The size of the largest link state advertisement that can be sent. |
# DIJKSTRA RUNS |
Indicates how many times the OSPF routing table has been calculated from scratch. |
INCREMENTAL SUMM UPDATES, INCREMENTAL VL UPDATES |
Indicate that new summary link advertisements have caused the routing table to be partially rebuilt. |
MULTICAST PKTS SENT |
Covers OSPF hello packets and packets sent during the flooding procedure. |
UNICAST PKTS SENT |
Covers OSPF packet retransmissions and the Database Exchange procedure. |
LS ADV. AGED OUT |
Indicates the number of advertisements that have hit 60 minutes. Link state advertisements are aged out after 60 minutes. Usually they are refreshed before this time. |
LS ADV. FLUSHED |
Indicates the number of advertisements removed (and not replaced) from the link state database. |
INCREMENTAL EXT. UPDATES |
Displays the number of changes to external destinations that are incrementally installed in the routing table. |
