Hello, Phil!
I supposed it to be so, but the message that ends being snooped is
the repetition of the actual normal package that was last sent by
the TestNetwork nodes. I can see it not only from the contents of
the payload, but from the sequence number, that is the same during
the frenzy blinking and returns to normal counting once the root
note goes back up.
Shouldn't the messages from the route discovery be any different?
If they were any different, I could filter the return so the serial
port wouldn't be flooded (I guess I can do that as well, with the
sequence number, though...).
Ah, good point. The CTP link estimator uses data traffic to probe
links. If you look at the ETX field of the packets you should see
them going up. Basically, loops manifest as flurries of packets to
discover and repair the loop. Since there is no possible repair, this
approach runs into issues. Basically, CTP tries really hard to
deliver packets, and so doesn't drop them except in extreme
situations. So the nodes keep on sending...
