As I haven't implemented DAD, but have= done ARP implementations, I think I could implement this 'enhanced DAD'. There are a few nits with the document: - There are several mentions of "hundred thousand" (and sometimes "hundred = thousands" and sometimes just hundreds or thousands), I'm not sure that thi= s is really that significant and just saying "lots" might be sufficient (I = don't see how the problem changes just because there are so many - yes, the= probability of a conflict may go up and the impact if not handled properly= is also much more significant). Anyway, if left the way it is, I am sure t= he RFC editor will fix the "hundred thousands". Again, this is minor but it= just seems better to remove these numeric quantities. - In section 4, 2nd paragraph, the sentence "Six bytes of random nonce is s= ufficiently large for collisions" needs to be fixed. I think they meant "is= sufficiently large to minimize collisions"? It is a bit ironic that 48-bit= s would be chosen when this is also the size of the mac-address, but mac-ad= dresses don't really use all 48-bits. (Though the next logical size given t= he limitations of the ND option sizes would be 6+8 =3D 14 bytes, which is u= nnecessarily large.) - In section 6, isn't this missing that there is no DoS protection against= a rogue node, on receiving a NS(DAD) to generate one which would appear to= be a looped backed packet (i.e., result in retransmitted probe and not all= owing the target address to move to assigned state - see section 4.2)? - There are places where "the" in missing. This will be handled by RFC edit= or. (If an 07 were to be published, there appear to be several native English c= o-authors, and perhaps one of them can go through the document.) Thus in the end the document is understandable and seems useful and impleme= ntable. - Bernie -----Original Message----- From: Int-dir [mailto:int-dir-bounces@ietf.org] On Behalf Of ????

List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Tue, 28 Oct 2014 18:26:35 -0000 Hi Ole: Please find my review below: "Two broadband modems" -> this sentence introduces the case after some disc= ussion. I'd have read better something like "In this scenario, two broadband modems ..." "PPP uses magic number" -> " the Point-to-Point Protocol (PPP) uses a magic= number" "=20 The mitigation options may not be effective for the bidirectional loopback (i.e. the loopback is placed in both directions of the circuit interface, so as to identify the faulty segment) if only one device followed a mitigation option specified in this document, since the other device would follow current behavior and disable IPv6 on that interface due to DAD until manual intervention restores it. " I think I understand; still I suggest to split and reword a bit this senten= ce " because two nodes that are" -> " because two nodes " " However, saving a nonce and nonce related data for all ND messages has impact on memory requirements of the node and also adds the algorithm state to a substantially larger number of ND messages. " -> needs rephrasing. Also, saving is not appropriate. =20 " If an IPv6 node implements the Enhanced DAD algorithm, the node MUST implement detection of looped back NS(DAD) messages during DAD for an interface address. " -> This rules seems to imply that if the code supports this RFC then it alw= ays has the nonce option.=20 Shouldn't that be a deployment choice, where this is the default but can be= turned off? The next sentence indicates a configuration which makes more sense to me: " If a node has been configured to use the Enhanced DAD algorithm" ", the interface moves the Target Address to the assigned state."=20 -> Please add: and discards the nonce. " If any probe is looped back within RetransTimer milliseconds after having sent DupAddrDetectTransmits NS(DAD) messages, the interface continues with another MAX_MULTICAST_SOLICIT number of NS(DAD) messages transmitted RetransTimer millseconds apart. "=20 millseconds->milliseconds I would have expected that the nonce is recomputed for these retries as ind= icated earlier in=20 " Also, becaus= e the nodes will have detected what appear to be looped back NS(DAD) messages, they will continue to probe, and it is unlikely that they will choose the same nonce the second time (assuming quality random number generators). " In 4.3 " If the interface does not receive any DAD failure indications within RetransTimer milliseconds after having sent DupAddrDetectTransmits Neighbor Solicitations, the interface moves the Target Address to the assigned state. " -> this text belongs to 4.2, and is already there In 4.4: I expect that both the CGA and the public key have better properties for u= niqueness validation than the nonce, so the send node should probably use t= hat first. 4.5 - I do not see that the introduction of 4862 is the best place for an RFC 2= 119 keyword. " For example, if the interface on an IPv6 node is connected to a circuit that supports loopback testing, then the node SHOULD implement the Enhanced DAD algorithm that allows the IPv6 interface to self-heal after loopback testing is ended on the circuit. Another example is when the IPv6 interface resides on an access concentrator running DAD Proxy. The interface supports up to a hundred thousand IPv6 clients (broadband modems) connected to the interface. =20 "-> please remove the normative text above that is redundant with the first= normative sentence below. " A network interface of an IPv6 node SHOULD implement the Enhanced DAD algorithm. " " One access network is a cable broadband" -> unsure what you mean? Is it "an access" or "one case of access" or els= e? 6. security I'd say 1) that this spec does not improve or reduce the security posture o= f RFC 4862 and 2) that SEND and SAVI are ways to protect against various at= tacks by onlink rogues. I hope this helps...
