spanning-tree mst max-hops

Hi Guys,

If I need to increase the maximum hops on our MST L2 network do I just need to do it on the root bridge or do I need to do it on all the switches within the MST instance?

spanning-tree mst max-hops 30

Thanks,

Ross.

My understanding is the BPDU is given a value for "remaining hops" from the configured max-hops by its originating switch.

The next switch decrements the value and discards it if it has reached zero.

The default value of 7 should cover even a very poorly-designed or unusual network, it it is probably inadvisable to be considering a design for a Layer-2 network with a depth any greater than 3 or 4.
