90
mask
: Specifies the mask in dotted decimal notation.
cost
cost
: Specifies the cost of the summary route, in the range of 1 to 16777214. Without this option, the
cost of Type-1 external routes defaults to the largest cost among routes that are summarized, and the cost
of Type-2 external routes defaults to the largest cost among routes that are summarized plus 1.
not-advertise
: Disables advertising the summary route. Without 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 marking 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
With the
asbr-summary
command configured, an ASBR summarizes redistributed routes within the
specified address range into a single route and advertises the summary route in a Type-5 LSA to
neighbors. If the ASBR resides in an NSSA area, it advertises the summary route in a Type-7 LSA.
With the
asbr-summary
command configured, an NSSA ABR summarizes matching routes described by
Type-7 LSAs, and advertises the summary route to neighbors in Type-5 LSAs. This command does not take
effect on non NSSA ABRs.
To enable ASBR to advertise more-specific routes, issue 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.
