да

по версии гугл-переводчика выглядит примерно так "attempt to prevent this problem by inferring that large payload packets have been dropped due to MTU"=="пытаются предотвратить эту проблему, подразумевая, что большие пакеты полезной нагрузки были сняты в связи с MTU"



Specifying Black Hole Thresholds

Some domains might be configured not to generate certain ICMP messages (like an ICMP destination unreachable message) or to filter all ICMP messages. Under these conditions, the source of oversized ICMP packets never learns that it is sending oversized packets. The device continues sending oversized packets that never get through. This behavior is often referred to as a black hole.

A black hole threshold is a limit to the number of times a virtual router can retransmit identical sequences of datagrams before the retransmissions are identified as a problem.
