Le 2 juin 2020 à 19:07, Etienne-Victor Depasquale <edepa@ieee.org> a écrit :


Hello,

Please bear with me as I put this question; I'm afraid it may have been thrashed out long ago.

RFC4903 states that:

"A multi-link subnet model should be avoided. IETF working groups
using, or considering using, multi-link subnets today should
investigate moving to one of the other models."

Now, draft-thubert-6man-ipv6-over-wireless-06 states that:
"routers federate the links between nodes
that belong to the subnet, the subnet is not on-link and it extends
beyond any of the federated links"

Is it correct to conclude that the draft runs counter to RFC4903?

Cheers,

Etienne
