Enabling MSTP
Context
After MSTP multi-process is enabled on the switching device, you must enable MSTP in the MSTP process view so that the MSTP configuration can take effect in the MSTP process.
Enabling MSTP immediately triggers spanning tree calculation on the network. Therefore, before enabling MSTP, perform basic configurations on switching devices to avoid network flapping, which may occur upon changes to parameters such as device priority and interface priority.
