Configuring the MSTP Maximum Hops

The MSTP maximum hops value is the maximum number of hops in the region. The MSTI root bridge sends BPDUs with the hop count set to the maximum value. When a bridge receives this BPDU, it decrements the remaining hop count by one and propagates this hop count in the BPDUs it sends. When a bridge receives a BPDU with a hop count of zero, the bridge discards the BPDU.

To configure the MSTP maximum hops, include the following statement:




max-hops hops;

You can configure this statement at the following hierarchy levels:

[edit protocols mstp]
[edit routing-instances routing-instance-name protocols mstp]
