I think that'll help avoid surprises by folks interested in MoFRR. I think what you are saying is that with non-DUAL plane topologies, there is no guarantee that the secondary path is going to be stable, un-interuppted traffic flow after switching to it. If the secondary path is effected by the same failure that effected the primary path, any sort of failure may apply here, including micro-loops. I don’t see any additional concerns regarding micro-loops with MoFRR, do you agree? I can add a statement regarding the above in the draft, but its its not specific to micro-loops..
