nssa-only
0. By default, the P-bit of Type-7 LSAs is set to 1. If the ASBR is also an ABR and FULL state
neighbors exist in the backbone area, the P-bit of Type-7 LSAs originated by the ASBR is set to 0.
This keyword applies to the NSSA ASBR.
: Specifies a tag for the summary route, in the range of 0 to 4294967295.
tag tag
Usage guidelines
An ASBR can summarize routes in the following LSAs:
•
Type-5 LSAs.
•
Type-7 LSAs in an NSSA area.
•
Type-5 LSAs translated by the ASBR (also an ABR) from Type-7 LSAs in an NSSA area.
If the ASBR (ABR) is not a translator, it cannot summarize routes in Type-5 LSAs translated
from Type-7 LSAs.
To enable ASBR to advertise specific routes that have been summarized, use the
asbr-summary
Examples
# Configure a summary route 2000::/16, and specify a cost of 100 and a tag value of 2 for the
summary route.

Usage guidelines
The authentication mode specified for an OSPFv3 interface has a higher priority than the mode
specified for an OSPFv3 area.
When keychain authentication is configured for an OSPFv3 area, OSPFv3 performs the following
operations before sending a packet:
1. Obtains a valid send key from the keychain.
: Limits the route advertisement to the NSSA area by setting the P-bit of Type-7 LSAs to
command.
to specify an authentication mode for an OSPFv3 area.
: Specifies a keychain by its name, a case-sensitive string of 1 to 63 characters.
