Re: [Roll] WGLC for draft-ietf-roll-efficient-npdao-03

["Liubing (Remy)" <[e-mail]>]

Hello Roll, Rahul and co-authors,

After reading the draft-ietf-roll-efficient-04, I found this draft useful. The problems, motivation and solutions are described quite clearly.

I have some minor comments:


1.       Does this draft require a new MOP to distinguish the original storing mode MOP?

2.       In the second paragraph of section 4.1, “In this case, Node A which is the common ancestor node for node D along the two paths (previous and new), may generate a DCO which traverses downwards in the network.” “traverses downwards in the network” should be clarified as “traverses downwards along the previous route”.

3.       The title of section 4.2 might be misleading. It proposes an update of transit information option instead of the DAO body itself. When reading the second paragraph of this section, I thought there was update to the DAO message body. The term “transit container option” should be “transit information option”?

4.       In section 4.4.1, how do dependent nodes know that the route is changed, so that the ‘I’ bit is set correctly?

Best regards,
Remy
