Configuring Priorities And Root Protection In Mstp Multi-Process; Configuring Tc Notification In Mstp Multi-Process - Huawei Quidway S7700 Configuration Manual - Ethernet

Quidway S7700 Smart Routing Switch
Configuration Guide - Ethernet
The interface specified in this command must be an interface on the share link between the
devices configured with MSTP multi-process but not the interfaces that connect an access ring
and a device.
Step 3 Run:
stp binding process process-id [ to process-id ] link-share
The interface is added to multiple MSTP processes to complete MSTP calculation.

9.3.5 Configuring Priorities and Root Protection in MSTP Multi-
process
You can configure priorities and root protection in MSTP multi-process to protect links over
access rings.
Context
To prevent loops over the access ring after the share links fails, configure priorities and root
protection in MSTP multi-process.
Root protection is configured on the access interface of a device with second highest priority.

9.3.6 Configuring TC Notification in MSTP Multi-process

After the TC notification function is configured for MSTP multi-process, the current MSTP
process can notify the 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
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
stp process process-id
Issue 01 (2011-07-15)
NOTE
For a process with share links, you must run the stp enable command globally. For an interface that is
added to the process in link-share mode, you must run the stp enable command in the interface view.
