Description
Configure a not-so-stubby area (NSSA). An NSSA
allows external routes to be flooded within the area. These routes
are then leaked into other areas.
You cannot configure an area as being both a stub area and an
NSSA.
The remaining statements are explained separately. See CLI Explorer.
Options
summaries | no-summaries—Configure whether or not area border routers advertise summary routes
into an not-so-stubby area (NSSA):
summaries—Flood summary link-state advertisements
(LSAs) into the NSSA.
no-summaries—Prevent area border routers
from advertising summaries into an NSSA. If default-metric is configured for an NSSA, a Type 3 LSA is injected into the
area by default.
Required Privilege Level
routing—To view this statement in the
configuration.
routing-control—To add this statement to the configuration.
