Enters area configuration mode and configures a
nonbackbone area for the OSPF process.
area area-id
Example:
Step 4
• The area-id argument can be entered in
dotted-decimal or IPv4 address notation, such as area
RP/0/RP0/CPU0:router(config-ospf)# area 1
1000 or area 0.0.3.232. However, you must choose
one form or the other for an area. We recommend using
the IPv4 address notation.
Defines the nonbackbone area as a stub area.Do one of the following:
Step 5
• stub [ no-summary ] • Specify the no-summary keyword to further reduce
the number of LSAs sent into a stub area. This
• nssa [ no-redistribution ] [
default-information-originate ] [ no-summary ]
keyword prevents the ABR from sending summary
link-state advertisements (Type 3) in the stub area.
Example:
RP/0/RP0/CPU0:router(config-ospf-ar)# stub no
summary
or
Defines an area as an NSSA.
or
RP/0/RP0/CPU0:router(config-ospf-ar)# nssa
no-redistribution
(Optional) Turns off the options configured for stub and
NSSA areas.
Do one of the following:
Step 6
• stub
• If you configured the stub and NSSA areas using the
optional keywords ( no-summary , no-redistribution
• nssa
Example:
, default-information-originate , and no-summary
RP/0/RP0/CPU0:router(config-ospf-ar)# stub
) in Step 5, you must now reissue the stub and nssa
commands without the keywords—rather than using
the no form of the command.
or
RP/0/RP0/CPU0:router(config-ospf-ar)# nssa
• For example, the no nssa
default-information-originate form of the command
changes the NSSA area into a normal area that
inadvertently brings down the existing adjacencies in
that area.
