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. This document is not an Internet Standards Track
specification; it is published for informational purposes.
This document is a product of the Operational Security Capabilities for IP Network Infrastructure Working Group of the IETF.
