not-advertise
: Disables advertising the summary route. If you do not specify this keyword, the
command advertises the route.
nssa-only
: Limits the 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 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.
tag tag
: Specifies a tag for the summary route, in the range of 0 to 4294967295. The default is 1.
The tag can be used by a routing policy to control summary route advertisement.
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
undo
asbr-summary
command.
Examples
# Summarize redistributed static routes into a single route, and specify a tag value of 2 and a cost of
100 for the summary route.

[Sysname] ip route-static 10.2.2.0 24 null 0
