Hello Ted
I do not have stats that I can expose, sorry for that, but switching parent=
is relatively frequent. Switching DODAG happens more often that we'd like.=
Either way there is nothing manual and the management is not involved. RPL=
handles the routing but if the other DODAG is a different subnet the node =
that moved needs to renumber and that is multiple round trips.
RPL is a form of L3 spanning tree when operated inside a subnet. There are =
advantages in forwarding at L3 within the subnet, e.g, TTL to avoid meltdo=
wn and NECM...
Cheers,
Pascal

How frequently do things change in the mesh? Does this require any manage=
