Configuring TC Notification in MSTP Multi-process

After the Topology Change (TC) notification function is configured for Multiple Spanning Tree Protocol (MSTP) multi-process, the current MSTP process can notify the Multiple Spanning Tree Instances (MSTIs) in other specified MSTP processes to refresh MAC address entries and ARP entries after receiving a TC-BPDU. Nonstop services are ensured.

Context

Do as follows on the devices connected to access rings:

Procedure

Run system-view
The system view is displayed.
Run stp process process-id
The view of the created MSTP process is displayed.
Run stp tc-notify process 0
TC notification is enabled in the MSTP process.

After the stp tc-notify process 0 command is run, the current MSTP process notifies the MSTIs in MSTP process 0 to update MAC entries and ARP entries after receiving a TC-BPDU. This prevents services from being interrupted.
Run commit
The configuration is committed.
