Huawei quidway s7700 - Adding an Interface to an MSTP Process - Access Links; Adding an Interface to an MSTP Process - Share Link

9.3.3 Adding an Interface to an MSTP Process - Access Links
The links connecting MSTP devices and access rings are called access links. After being added
to MSTP processes, interfaces on the access links can participate in MSTP calculation.
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:
interface interface-type interface-number
The Ethernet interface view is displayed.
Step 3 Run:
stp binding process process-id
The current interface is added to the MSTP process.
NOTE
If the interface added to the MSTP process has sub-interfaces configured with features other than MSTP
such as VPLS, run the stp vpls-subinterface enable command on the main interface. The main interface
can then notify its sub-interfaces to update MAC entries and ARP entries after receiving a TC-BPDU. This
prevents services from being interrupted. In addition, root protection needs to be configured on the main
interface.

9.3.4 Adding an Interface to an MSTP Process - Share Link
The link shared by multiple access rings are called a share link. The interfaces on the share link
need to participate in MSTP calculation in multiple access rings in different MSTP processes.
After being added to MSTP processes, interfaces on the access links can participate in MSTP
calculation.
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:
interface interface-type interface-number
The Ethernet interface view is displayed.
