The starting point (still using your example):

rebroadcast the packets from C because they are slower than the
packets via A.
* C uses the longer path.
Your idea: Use the echo cancellation's answer to retrieve more information,
especially when the TQ which is coming back is worse than my own I update my
The situation now:
* A still points to E because the echos coming from B do not contain TQ values
that are worse than its own.
* B will probably never route via A because the TQ values are much worse.
* C is not affected.
Did I overlook something ?
