OSPFv3 Commands 1183
area range (Router OSPFv3)
Use the area range command in Router OSPF Configuration mode to
configure a summary prefix for routes learned in a given area. If the area has
not been previously created, this command creates the area and then applies
the range parameters. 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 remove the summary
prefix configuration for routes learned in the specified area.
