Best Practices for STP with MLAG:
- The STP global configuration must be the same on both the switches.
- The STP configuration for dual-connected ports should be the same on both peer switches.
The STP priority must be the same on both peer switches. You set the priority with this command:
Code Block language text
cumulus@switch:~$ net add bridge stp treeprio PRIORITY_VALUE cumulus@switch:~$ net commit
- Use NCLU (
net) commands for all spanning tree configurations, including bridge priority, path cost and so forth. Do not use
brctlcommands for spanning tree, except for
brctl stp on/off, as changes are not reflected to
mstpdand can create conflicts.
