mask-length: Specifies the mask length in the range of 0 to 32 bits.
cost cost: Specifies the cost of the summary route, in the range of 1 to 16777214. For Type-1 external
routes, the cost defaults to the largest cost among routes that are summarized. For Type-2 external routes,
the cost 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.
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 that fall into 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-5 LSAs that are translated from Type-7 LSAs, and advertises the summary route to neighbors. 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.
