27.3.11 Configure an Area as NSSA
Syntax [no] nssa [no-summary]
Context OSPF Area Configuration context
Usage Configure an area as a nssa area. To create a nssa area, all routers in
the area (ABRs as well as internal routers) must declare the area as nssa.
To configure the area as a NSSA totally stub area, all ABRs in the area should
add the no-summary parameter to the nssa command (”nssa no-summary”).
Use ”no nssa” to let a nssa (or stub) area become a regular area.
Use ”show nssa” to show whether this area is configured as NSSA or not. If
this is a NSSA area, it will show whether the ”no-summary” keyword is set
or not, i.e., if it is a NSSA totally stub area or just a NSSA area.
Default values Disabled (i.e., areas are ”regular” OSPF areas by default)
27.3.12 Configure default route cost in stub and NSSA areas
Syntax [no] default-cost
Context OSPF Area Configuration context
Usage Configure the cost of the default route injected into a stub area. This
setting only applies to the ABRs of a stub or NSSA area.
Use ”no default-cost” to use the default value for the default cost setting.
Use ”show default-cost” to show the setting of the default-cost, i.e., the
cost of the default route injected by ABRs into a stub or NSSA area.
Default values ”default-cost 0”
27.3.13 Configure inter-area route summarisation and filtering
Syntax [no] range <NETWORK/LEN> [<advertise|not-advertise]
Context OSPF Area Configuration context
Usage Configure inter-area route summarisation or route filtering.
