OSPFv3 Commands

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.
