The BPDUs sent out by the root switch set theremaining-hops parameter to the configured value of max-hops. When a switchreceives the BPDU, it decrements the received value of the remaining hops and usesthe resulting value as remaining-hops in the BPDUs. If the remaining-hops reach zero,the switch discards the BPDU and ages out any information that it holds for the port.Multiple Spanning Tree Protocol (MSTP) 1426
