Command Usage
An MSTI region is treated as a single node by the STP and RSTP
protocols. Therefore, the message age for BPDUs inside an 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
spanning-tree spanning-disabled
This command disables the spanning tree algorithm for the specified
interface. Use the no form to reenable the spanning tree algorithm for the
specified interface.
