Reduced Occurrences of MSTP Reconvergence
When a VLAN is deleted, the RUCKUS device retains the associated VLAN to MSTI mapping instead of deleting it from the configuration. This way, a VLAN can be pre-mapped to an MSTI and MSTP reconvergence may not be necessary when a VLAN is added to or deleted from the configuration. As long as the VLAN being created or deleted is pre-mapped to an MSTI, and the VLAN to MSTI mapping has not changed, MSTP reconvergence will not occur.
Note:
MSTP reconvergence occurs when the VLAN to MSTI mapping is changed using the mstp instance
command.
You can optionally remove VLAN to MSTI mappings from the configuration. Refer to Deleting a VLAN to MSTI Mapping.
The following shows an example application.
