R0106-HP MSR Router Series Layer 3 - IP Routing Command Reference(V7)

541
Parameters
default-route-advertise: Used on an NSSA ABR or an ASBR only. If it is configured on an NSSA ABR, the
ABR redistributes a default route in a Type-7 LSA into the NSSA area. It redistributes a default route
regardless of whether a default route exists in the routing table. If it is configured on an ASBR, the ASBR
redistributes a default route in a Type-7 LSA only when the default route exists in the routing table.
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.
nssa-only: Limits the default route advertisement to the NSSA area by setting the P-bit of Type-7 LSAs to
0. By default, the P-bit of Type-7 LSAs is set to 1. If the router acts as both an ASBR and an ABR and FULL
state neighbors exist in the backbone area, the P-bit is set to 0.
route-policy route-policy-name: Specifies a routing policy by its name, a case-sensitive string of 1 to 63
characters. When the specified routing policy is matched, the command redistributes a default route in
a Type-7 LSA into the OSPFv3 routing domain. The routing policy modifies values in the Type-7 LSA.
tag tag: Specifies a tag for the default route, in the range of 0 to 4294967295. If this option is not
specified, no tag is contained in advertised LSAs by default.
type type: Specifies a type for the Type-7 LSA, 1 or 2. The default 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. The area is a totally NSSA area.
translate-always: Always translates Type-7 LSAs to Type-5 LSAs. This keyword takes effect only on an
NSSA ABR.
translate-never: Never translates Type-7 LSAs to Type-5 LSAs. This keyword takes effect only on an NSSA
ABR.
suppress-fa: Suppresses the forwarding address in the Type-7 LSAs from being placed in the Type-5
LSAs.
translator-stability-interval value: Specifies the stability interval of the translator. During the interval the
translator can maintain its translating capability after a device with a higher priority becomes the new
translator. The value argument is the stability interval in the range of 0 to 900 seconds. The default
interval is 0. A value of 0 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.
Examples
# Configure Area 1 as an NSSA area.
<Sysname> system-view
[Sysname] ospfv3 120
[Sysname-ospfv3-120] area 1
[Sysname-ospfv3-120-area-0.0.0.1] nssa
