Usage Guideline
This command is used only on an ABR attached to a stub area. In all routers and
access servers attached to the stub area, the area should be configured as a
stub area using the
area stub
command. Use the
area default-cost (IPv6)
command on page 40
only on an ABR attached to the stub area. The
area
default-cost
command provides the metric for the summary default route
generated by the ABR into the stub area.
Use the
no-summary
argument with this command to define a totally stubby
area. When routers in the area do not require to learn about summary LSAs from
other areas, then a totally stubby area should be defined. To define a totally
stubby area configure the ABR of that area using the
area stub no-summary
command.
Examples
In the following example, the
area stub
command is used to configure the router
as a stub that advertises connected and summary routes.
Syntax Description
AREA-ID

specified as either a decimal value or as an IPv4 address.

(Optional) Prevent an ABR from sending summary link advertisements into the
stub area.
