The chair has pointed out this discussion should stop. And strictly I'm violating that. But find another person, one who understands OLSRv2 but not MT-OLSRv2, then there may be something to say.

In subsection 6.8 it does not describe how is the separation. In section 11 it does not describe how the calculation separates routing sets. The is a need to add an element in routing set for metric type. All maps are done with metric type reference, but in the routing sets there is no element for metric type or reference.

The reader is referring to texts in the draft related to updating routing sets. Generally, the case is that some of my questions are not getting clear answers. It is good that reader reviewing and commenting on draft and sharing his/her understanding or misunderstanding. I want to implement the work then will think about scenarios.

Or stop because you have no scenario detail (usually my scenario is the draft scenario). The WG is small in size so maybe 10% participants don't understand the work. The IETF is not about only consensus, but about publishing readable work that full community can understand and implement.
