specific intra-area route as a type 3 summary LSA. Also, an area range can be configured at the edge of an NSSA to summarize external routes reachable within the NSSA. The range is advertised as a type 5 external LSA. Use the no form of the command to delete an area range or revert an option to its default. Syntax area area-id range prefix netmask {summarylink | nssaexternallink} [advertise | not-advertise][cost cost] no area area-id range prefix netmask {summarylink | nssaexternallink} • area-id -Identifies the OSPF NSSA to configure. (Range: IP address or decimal from 0-4294967295) • prefix netmask-The summary prefix to be advertised when the ABR computes a route to one or more networks within this prefix in this area. • summarylink-When this keyword is given, the area range is used when summarizing prefixes advertised in type 3 summary LSAs. • nssaexternallink-When this keyword is given, the area range is used when translating type 7 LSAs to type 5 LSAs. • advertise-[Optional] When this keyword is given, the summary prefix is advertised when the area range is active. This is the default. • not-advertise-[Optional] When this keyword is given, neither the summary prefix nor the contained prefixes are advertised when the area range is active. Then the not-advertise option is given, any static cost previously configured is removed from the system configuration. • cost-[Optional] If an optional cost is given, OSPF sets the metric field in the summary LSA to the configured value, rather than setting the metric to the largest cost among the networks covered by the area range. A static cost may only be configured if the area range is configured to advertise the summary. The range is 0 to 16,777,215. If the cost is set to 16,777,215 for type 3 summarization, a type 3 summary LSA is not advertised, but contained networks are suppressed. This behavior is equivalent to specifying the not-advertise option. If the range is configured for type 7 to type 5 translation, a type 5 LSA is sent if the metric is set to 16,777,215; however, other routers will not compute a route from a type 5 LSA with this metric.
