Obtaining OSPF Neighbor Information
Obtain OSPF neighbor information if you want details about the neighboring routers of
an SSR. To access this information:
1.
If you are not in the Front Panel view, switch to it by clicking the CoreWatch main
window.
2.
Select the Monitor menu, choose Routing State, choose OSPF State, and then choose
OSPF Neighbor Table.
410
Indicates how many area border routers are reachable within
the area. The value of this field is initially zero (0), and is
calculated in each SPF run.
Indicates how many autonomous system border routers are
reachable within the area. The value of this field is initially
zero (0), and is calculated in each SPF run.
Indicates how many link-state advertisements are in the area's
link-state database. The value in this field does not include
link-state advertisements of external autonomous systems.
Identifies the 32-bit unsigned sum of the link-state
advertisements' link-state checksums contained in the area's
link-state database. The value in this field excludes external
(LS type 5) link-state advertisements.
You may use this figure to determine if there has been a
change in a router's link state databases, and to compare the
link-state database of two routers.
Indicates whether the SSR imports summary link-state
advertisements into stub areas. This field has no effect on other
areas.
If the value of this field is noAreaSummary, the SSR will
neither originate nor propagate summary link-state
advertisements into the stub area. It will rely entirely on its
default route.
If it is sendAreaSummary, the SSR will both summarize and
propagate summary link-state advertisements.
Indicates the status of the entry. This field's value is always
valid.
