Advanced Configuration and Management Guide
The <num> | <ip-addr> parameter specifies the area number, which can be a number or in IP address format. If
you specify an number, the number can be from 0 – 2,147,483,647.
The nssa parameter specifies that this is an NSSA. For more information about configuring NSSAs, see “Assign
a Not-So-Stubby Area (NSSA)” on page 8-11.
The <cost> specifies an additional cost for using a route to or from this area and can be from
1 – 16777215. If you configure a stub area or NSSA, you must specify the cost. There is no default. Normal
areas do not use the cost parameter.
The no-summary parameter applies only to stub areas and disables summary LSAs from being sent into the
area. See
“Assign a Totally Stubby Area” on page 8-11.
NOTE: You can assign one area on a routing switch interface. For example, if the system or chassis module has
16 ports, 16 areas are supported on the chassis or module.
