Configuring OSPFv3
The following example modifies the NSSA area 100 wherein type-7 NSSA external LSA will not be
originated into NSSA area. But the type-3 summary LSAs will still be originated into NSSA area.
Brocade(config-ospf6-router)# area 100 nssa no-redistribution
The following example modifies the NSSA area 100 wherein origination of type-3 summary LSAs
(apart from type-3 default summary) will be blocked into NSSA area. The CLI works in incremental
fashion and the origination of type-7 LSA will be continued to be blocked as 'no-redistribution'
option was enabled in the previous command.
Brocade(config-ospf6-router)#area 100 nssa no-summary
The following example modifies the NSSA area 100 wherein origination of the self-router acts as
NSSA translator. The generation of type-3 & type-7 LSA will still be blocked into NSSA area.
Brocade(config-ospf6-router)#area 100 nssa translator-always
The following example modifies the NSSA area 100 wherein origination of type-3 summary will be
allowed, but origination of type-7 LSA will still be blocked. Also the self-router will still act as NSSA
translator-always.
Brocade(config-ospf6-router)#no area 100 nssa no-summary
Although the NSSA configuration can be done in an incremental fashion during show-run, all the
configuration options will be displayed in just one line. For example, the output of the show run
would be:
Brocade(config-ospf6-router)#area 100 nssa no-redistribution translator-always
The following example deletes the NSSA area 100.
Brocade(config-ospf6-router)#no area 100
Syntax: [no] area area-id nssa [[stub-metric ] [default-information-originate [metric metric-value |
metric-type type-value]] [no-summary] [no-redistribution] [translator-always]
[translator-interval stability-interval]]
The area-id parameter specifies the area number, which can be a number or in IP address format.
If you specify a number, the number can be from 0 to 2,147,483,647.
The nssa stub-metric parameter configures an area as a not-so-stubby-area (NSSA). The
stub-metric will be the metric used for generating default LSA in a NSSA. The range of the value is 1
to 1048575. The default value is 10.
The default-information-originate parameter generates a default route into an NSSA. If no-summary
option is enabled then a type-3 default LSA will be generated into NSSA else a type-7 LSA will be
generated into NSSA. By default the default-information-originate parameter is not set.
The metric metric-value parameter specifies the cost of the default LSA originated into the NSSA
area. The range is 1 to 1048575. There is no default
The metric-type type-value parameter specifies the type of the default external LSA originated into
the NSSA area. It can be either type-1 or type-2. The default is type-1.
The no-summary parameter prevents an NSSA ABR from generating a type-3 summary into an
NSSA. By default the summary LSA is originated into NSSA.
