The maximum number of non-default AS-
external-LSAs entries that can be stored in the
link-state database. If the value is -1, then
there is no limit.
When the number of non-default AS-external-LSAs
in a router's link-state database reaches
nsVrOspfExtLsdbLimit, the router enters Overflow-
State. The router never holds more than
nsVrOspfExtLsdbLimit non-default AS-external-LSAs
in its database. OspfExtLsdbLimit MUST be set
identically in all routers attached to the OSPF
backbone and/or any regular OSPF area. (i.e.,
OSPF stub areas and NSSAs are excluded).
