Table9-6. OSPF Statistical Parameters
Parameter Displays the...
OSPF State Current state of OSPF.
Router ID Router ID for OSPF.
OSPF Version Current version of OSPF. The P550 with Integrated Routing
supports OSPFv2.
External LSA Count Number of external (LS type 5) link-state advertisements in the
link-state database.
Originate LSA Count Number of LSAs originated by this router.
Receive New LSA
Count
Number of new LSAs received by this router.
LSA Checksum Sum
(global OSPF system)
32-bit unsigned sum of the LS checksums of the external
link-state advertisements contained in the link-state database.
This sum can be used to determine if there has been a change in
a router's link state database, and to compare the link-state
database of two routers.
Area ID Area ID of the area in question. It has the function of defining a
summarization point for Link State Advertisements.
SPF Runs Number of times that the intra-area route table has been
calculated using this area's link-state database.
Border Rtrs Total number of area border routers reachable within this area.
This is initially zero, and is calculated in each SPF Pass.
AS Border Rtrs Total number of Autonomous System border routers reachable
within this area. This is initially zero, and is calculated in each
SPF Pass.
LSAs Total number of link-state advertisements in this area's link-state
database, excluding AS External LSAs.
LSA Chksum Sum
(per area, not
globally)
32-bit unsigned sum of the LS checksums of the external
link-state advertisements contained in the link-state database.
This sum can be used to determine if there has been a change in
a router's link state database, and to compare the link-state
database of two routers.
