Implement NSSA address ranges as specified by RFC 3101: NSSA border routers may be configured with Type-7 address ranges. Each Type-7 address range is defined as an [address,mask] pair. Many separate Type-7 networks may fall into a single Type-7 address range, just as a subnetted network is composed of many separate subnets. NSSA border routers may aggregate Type-7 routes by advertising a single Type-5 LSA for each Type-7 address range. The Type-5 LSA resulting from a Type-7 address range match will be distributed to all Type-5 capable areas. Syntax: area A.B.C.D nssa range A.B.C.D/M [<not-advertise|cost (0-16777215)>] Example: router ospf router-id 1.1.1.1 area 1 nssa area 1 nssa range 172.16.0.0/16 area 1 nssa range 10.1.0.0/16 ! Since regular area ranges and NSSA ranges have a lot in common, this commit reuses the existing infrastructure for area ranges as much as possible to avoid code duplication.
