Statement introduced before Junos OS Release 10.2 for J-EX Series switches.
(Area border routers only) For an area, summarize a range of IP addresses when sending
summary link advertisements (within an area). To summarize multiple ranges, include
multiple statements.
area-range
For a not-so-stubby area (NSSA), summarize a range of IP addresses when sending
NSSA link-state advertisements. The specified prefixes are used to aggregate external
routes learned within the area when the routes are advertised to other areas. To specify
multiple prefixes, include multiple
within the area that do not fall into one of the prefixes are advertised individually to other
areas.
By default, area border routers do not summarize routes being sent from one area to
other areas, but rather send all routes explicitly.
—(Optional) Summarization of a route is advertised only when an exact match is
exact
made with the configured summary range.
—Number of significant bits in the network mask.
mask-length
network —IP address. You can specify one or more IP addresses.
—(Optional) Override the metric for the IP address range and
override-metric metric
configure a specific metric value.
restrict —(Optional) Do not advertise the configured summary. This hides all routes that
are contained within the summary, effectively creating a route filter.
