undo instance instance-id [ vlan vlan-list ]
Default
All VLANs are mapped to the CIST.
Views
MST region view
Default command level
2: System level
Parameters
instance-id: Specifies an MSTI ID. The value range for this argument is 0 to 31. The value 0 represents the
CIST.
vlan vlan-list: Specifies a VLAN list in the format of vlan-list = { vlan-id [ to vlan-id ] }&<1-10>, where the
vlan-id argument represents the VLAN ID in the range of 1 to 4094, and &<1-10> indicates that you can
specify up to 10 VLAN IDs or VLAN ID ranges.
Usage guidelines
If you specify no VLAN in the undo instance command, all VLANs mapped to the specified MSTI will be
remapped to the CIST.
You cannot map the same VLAN to different MSTIs. If you map a VLAN that has been mapped to an MSTI
to a new MSTI, the old mapping will be automatically removed.
After configuring this command, run the active region-configuration command to activate the
VLAN-to-instance mapping.
Examples
# Map VLAN 2 to MSTI 1.

[Sysname] stp region-configuration
