area range (Router OSPF)
Use the area range command in Router OSPF Configuration mode to
configure a summary prefix that an area border router advertises for a specific
area. There are two types of area ranges. An area range can be configured to
summarize intra-area routes. An ABR advertises the range rather than the
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.

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.
