Hello Rahul:

Attracting your attention on the particular point below in Alvaro's AD review of unaware leaves:

The change Alvaro and I want to make in the efficient npdao draft is that the DCO status is now of the same type as the RPL status in DAO ACK, and should be specified as such in https://tools.ietf.org/html/draft-ietf-roll-efficient-npdao-18#section-4.3.4

Which means that we do not need the registry that we ask for in https://tools.ietf.org/html/draft-ietf-roll-efficient-npdao-18#page-17



Do you agree?


Keep safe!
