Could I suggest that, rather than second-guessing what some putative router might or might not do, people actually try these scenarios with one of the many real-world routers to see if they actually happen?
I see an awful lot of "may" and "might" in this thread, together with a liberal sprinkling of unsourced assertions, but no actual evidence that any router has ever sent anyone round one of these roundabout flares. Richard
