934 OSPFv3 Commands
area range
Use the area range command in Router OSPF Configuration mode to
configure a summary prefix for routes learned in a given 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 remove the summary prefix configuration for routes learned in the
specified area.
