Hello Maxence During a sequence transition, the draft says that a child using
the older sequence can use a ‘future’ parent with the newer
sequence. To avoid false positive in the loop detection mechanism, the
rank is the Flow Label must be reset so the child appears as a host to its
parent. With what we discuss here, say a node that was
router for sequence N-1 becomes non-router for sequence N. So the node never advertises
N and all its children that see N should migrate over a transition period and
stop using that parent. Over the transition period, the node should still perform as a
N-1 router, acting as prescribed in the draft today, that is resetting the rank
in the flow label for all packets it issues or forwards. Pascal From: Maxence Dalmais
