          Issues with Existing Cryptographic Protection Methods                          for Routing Protocols


   Routing protocols have been extended over time to use cryptographic    mechanisms to ensure that data received from a neighboring router has    not been modified in transit and actually originated from an    authorized neighboring router.

   The cryptographic mechanisms defined to date and described in this    document rely on a digest produced with a hash algorithm applied to    the payload encapsulated in the routing protocol packet.

   This document outlines some of the limitations of the current    mechanism, problems with manual keying of these cryptographic    algorithms, and possible vectors for the exploitation of these    limitations.
