Setting the hop limit for BPDUs


spanning-tree max-hops hop-count

Resets the number of hops allowed for BPDUs in an MST region. When an MSTP switch receives a BPDU, it decrements the hop-count setting the BPDU carries. If the hop-count reaches zero, the receiving switch drops the BPDU.

The switch does not change the message-age and maximum-age data carried in the BPDU as it moves through the MST region and is propagated to other regions.

Range: 1 - 40

Default: 20
