Abstract:
This memo documents an optional type of Open Shortest Path First (OSPF) area
that is somewhat humorously referred to as a "not-so-stubby" area (or NSSA). NSSAs are
similar to the existing OSPF stub area configuration option but have the additional capability
of importing AS external routes in a limited fashion. The OSPF NSSA Option was
originally defined in RFC 1587. The functional differences between this memo and RFC 1587
are explained in Appendix F. All differences, while expanding capability, are
backward-compatible in nature. Implementations of this memo and of RFC 1587 will interoperate.
