We're not doing routing. We're determining whether packets make it to the egress. > Again, this does not make me happy because I have been trying to figure > out for years how to make tunnels probe the MTU. If the probe makes it, it makes it. If the probe "would have failed" on another path, you'll either see that over several probes or not. If you do, you have what is isomorphic to a lossy link, and you decide how you want to handle that - if you can fragment to get around it, then you might try that. If you have FEC, you might try that. The cause of the losses is irrelevant.
