Adding an Interface to an MSTP Process
Context
After being added to MSTP processes, interfaces can participate in MSTP calculation. Interfaces can be added to one of the following two types of link:
The links connecting MSTP-enabled devices and access rings are called access links.
The link shared by multiple access rings is called a shared link. Interfaces on this shared link participate in MSTP calculation in multiple access rings and MSTP processes.
Procedure
- Adding an interface on an access link to an MSTP process
- Adding an interface on a shared link to an MSTP process
- Run stp binding process process-id1 [ to process-id2 ] link-share
The interface is added to multiple MSTP processes to complete MSTP calculation.
In an MSTP process where there are multiple shared links, run the stp enable command in the MSTP multi-instance view. On an interface that is added to an MSTP process in link-share mode, run the stp enable command in the interface view.
- Run stp binding process process-id1 [ to process-id2 ] link-share
