There are two types of issues that need be addressed when looking at
   protecting routing protocols from misconfigurations and malicious
   attacks.  The first is authentication and certification of routing
   protocol information.  The second is denial of service attacks
   resulting from repetitive origination of the same router
   advertisement or origination of a large number of distinct
   advertisements resulting in database overflow.  Note that both of
   these concerns exist independently of a router's support for the NSSA
   option.(http://tools.ietf.org/html/rfc3101)
