After the TC notification function is configured for MSTP multi-process, an MSTP process can notify the MSTIs in other specified MSTP processes to refresh MAC address entries and ARP entries after receiving a TC-BPDU. This ensures service continuity. To configure the TC notification function for MSTP multi-process, perform the following procedure on the devices connected to access rings.
The system view is displayed.
The view of the created MSTP process is displayed.
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.
