Deleting a VLAN to MSTI Mapping

You can optionally remove a VLAN to MSTI mapping using the no mstp instance command. To do so, enter a command such as the following.

device(config)# no mstp instance 7 vlan 4 to 7 

This command deletes the VLAN to MSTI mapping from the running configuration and triggers an MSTP reconvergence.
