NSSA Support in OSPFv3
=======================
The configuration of NSSA areas in OSPFv3 is supported using the CLI command
area A.B.C.D nssa in ospf6 router configuration mode.
The following functionalities are implemented as per RFC 3101:
1. Advertising Type-7 LSA into NSSA area when external route is redistributed
into OSPFv3
2. Processing Type-7 LSA received from neighbor and installing route in the
route table
3. Support for NSSA ABR functionality which is generating Type-5 LSA when
backbone area is configured. Currently translation od TYpe-7 LSA to Type-5 LSA
is enabled by default.
4. Support for NSSA Translator functionality when there are multiple NSSA ABR
in an area
