Command Usage

A MSTI region is treated as a single node by the STP and RSTP protocols. Therefore, the message age for BPDUs inside a MSTI region is never changed. However, each spanning tree instance within a region, and the internal spanning tree (IST) that connects these instances use a hop count to specify the maximum number of bridges that will propagate a BPDU. Each bridge decrements the hop count by one before passing on the BPDU. When the hop count reaches zero, the message is dropped.

Example

Console(config-mstp)#max-hops 30

Console(config-mstp)#

4-218
