area range (OSPFv3)

Use this command to configure a summary prefix that an area border router advertises for a specific area.

Default	No area ranges are configured by default. No cost is configured by default.
Format	`area area-id range prefix netmask {summarylink \| nssaexternallink} [advertise \| not-advertise] [cost cost]`
Mode	Router OSPFv3 Config

Parameter	Description
area-id	The area identifier for the area whose networks are to be summarized.
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. When 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 inter-area -prefix LSA to the configured value rather than setting the metric to the largest cost among the networks covered by the area range.
