R3102-R3103-HP 6600/HSR6600 Routers Layer 3 - IP Routing Command Reference

371
default route is available in the routing table. If it is configured on an ASBR, the ASBR generates a default
route in an NSSA-external-LSA only when the default route is available in the routing table. By default, an
NSSA ABR or an ASBR does not generate a default route in an NSSA-external-LSA into the NSSA area.
cost cost: Specifies a cost for the default route, in the range of 0 to 16777214. If no cost is specified, the
default cost specified by the default-cost command applies. If no cost is specified by the default-cost
command, the default cost specified by the default cost command applies.
type type: Specifies a type for the NSSA-external-LSA: 1 or 2. The default type is 2.
no-import-route: Used on an NSSA ABR to control the import-route command to not redistribute routes
into the NSSA area.
no-summary: Used only on an ABR to advertise a default route in a Type-3 summary LSA into the NSSA
area and to not advertise other summary LSAs into the area. Such an area is a totally NSSA area.
suppress-fa: Suppresses the forwarding address in the NSSA-external-LSAs from being placed in the
AS-external LSAs.
translate-always: Always translates NSSA-external-LSAs to AS-external LSAs. This keyword takes effect
only on an NSSA ABR.
translate-never: Never translates NSSA-external-LSAs to AS-external LSAs. This keyword takes effect only
on an NSSA ABR.
translator-stability-interval value: Specifies the stability interval of the translator, during which the
translator can maintain its translating capability after a device with a higher priority becomes the new
translator. The value argument is in the range of 0 to 900 seconds and the default is 0 (which means the
translator does not maintain its translating capability when a new translator arises).
Usage guidelines
All routers attached to an NSSA area must be configured with the nssa command in area view.
When the default-route-advertise keyword is specified, a router uses the cost specified by the following
commands in a descending order: the nssa command with the default-route-advertise keyword
specified, the default-cost command, and the default cost command.
Examples
# Configure OSPFv3 area 1 as an NSSA area.
<Sysname> system-view
[Sysname] ospfv3 100
[Sysname-ospfv3-100] area 1
[Sysname-ospfv3-100-area-0.0.0.1] nssa
maximum load-balancing (OSPFv3 view)
Use maximum load-balancing to configure the maximum number of equal-cost multi-path (ECMP) routes
for load balancing.
Use undo maximum load-balancing to restore the default.
