Folks, I have just published an Internet-Draft entitled "Security Assessment of the IPv6 Flow Label" that analyzes the security implications of the Flow Label header field, and proposes a scheme to set the Flow Label that is compliant with RFC 3697, and compatible with draft-blake-ipv6-flow-label-

Isn't this a case where what we really want is MUST implement and SHOULD enable? If I bought a router, I would expect it to be capable of redirecting but I might want to disable it. Regards Brian On 2010-08-13 07:47, Alain Durand wrote: > I have a question about draft-ietf-6man-node-req-bis-0

Router redirects in Node Requirements document

2010-08-12 Thread Alain Durand
I have a question about draft-ietf-6man-node-req-bis-05.txt. Section 5.2: Redirect functionality SHOULD be supported. If the node is a router, Redirect functionality MUST be supported. However, draft-ietf-6man-node-req-bis-05.txt refer to the normative text on Neighbor Discovery, ie RFC48

Hi, I support the adoption of this document as WG draft. The described solution is used in the proposal "Duplicate Address Detection Proxy" (http://tools.ietf.org/html/draft-costa-6man-dad-proxy-00) to avoid multicasted messages (i.e. flooding) in a VLAN. Best regards. JMC. 2010/7/31 Fred Baker

Yes, Rémi, you are. We have explained that inserting data requires a new header and thus IP in IP encapsulation. This happens for instance when a packet comes from the Internet into a RPL network. Which we can hardly accept in constrained networks an devices. In most cases, we could squeeze the
