RFC1918 specifically addresses filtering routing information.  Not spoofed
addresses.  It states "routing information about private networks shall
not be propagated on inter-enterprise links, and packets with private
source or destination addresses should not be forwarded across such
links."  Notice the placement of "shall" and "should."

Although 1918 was given only as an example, substituting the number 1918 for
2827 is a common mistake.  RFC 2827 addresses spoofing and is a BCP.  You
can't argue that widespread implementation of RFC 2827's concepts wouldn't
benefit the Internet.

Now, in specific response to your question about eliminating electronic
terrorism, it is doubtful.  Doubtful that you'll ever: #1 spread enough
clue around. #2 get everyone to cooperate.

This can't go on forever.  I'd like to spread the clue about ingress
filtering, and am willing to commit time to the cause.  Is anyone with me?
