ProSafe M4100 and M7100 Managed Switches Parameter area-id prefix netmask summarylink nssaexternallink advertise not-advertise cost Description The area identifier for the area whose networks are to be summarized. The summary prefix to be advertised when the ABR computes a route to one or more networks within this prefix in this area. When this keyword is given, the area range is used when summarizing prefixes advertised in type 3 summary LSAs. When this keyword is given, the area range is used when translating type 7 LSAs to type 5 LSAs. [Optional] When this keyword is given, the summary prefix is advertised when the area range is active. This is the default. [Optional] When this keyword is given, neither the summary prefix nor the contained prefixes are advertised when the area range is active. When the not-advertise option is given, any static cost previously configured is removed from the system configuration. [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 might only be configured if the area range is configured to advertise the summary. The range is 0-16,777,215. 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. no area range The no form of this command deletes a specified area range or reverts an option to its default. Format Mode no area areaid range prefix netmask {summarylink | nssaexternallink} [advertise | not-advertise] [cost] OSPFv2 Router Configuration area stub (OSPF) This command creates a stub area for the specified area ID. A stub area is characterized by the fact that AS External LSAs are not propagated into the area. Removing AS External LSAs and Summary LSAs can significantly reduce the link state database of routers within the stub area. Format Mode area stub Router OSPF Config Routing Commands 268
