ospf6d: add support for NSSA Type-7 address ranges
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 X:X::X:X/M [<not-advertise|cost (0-16777215)>]
Example:
router ospf6
ospf6 router-id 1.1.1.1
area 1 nssa
area 1 nssa range 2001:db8:1000::/64
area 1 nssa range 2001:db8:2000::/64
