As you know, I agree with this (per Section 3.13 of AERO) but it is not exactly like RFC4821. With RFC4821, since the source of the probes is also the original source of the data packets (and, since the probes are actually data packets themselves) the probes are guaranteed to travel the same network path as the data packets. When the tunnel probes, however, it may be probing on behalf of many original sources and it becomes more difficult to ensure that the probes travel the same network path as the data packets. For this reason, the tunnel needs to be meticulous about how it assigns n-tuples to the probes and encapsulated data packets.
