Re: [OPSEC] I-D Action: draft-ietf-opsec-dhcpv6-shield-07.txt

["C. M. Heard" <[e-mail]>]

Greetings,

The text in Section 3 seems to have dropped the step saying that if 
the packet is identified to be a DHCPv6 packet meant for a DHCPv6 
client then a DHCPv6-Shield implementation MUST drop the packet.  
That omission defeats the entire purpose of the draft and renders it 
unsuitable for publication.

As noted in http://www.ietf.org/mail-archive/web/opsec/current/msg01870.html, 
this problem was introduced in the -06 version of the draft.  Could the authors 
PLEASE fix this, or else point out where in -07 this step is spelled out?
