Usage Scenario
When you configure a Layer 2 ring protocol, run the instance vlan command in the VLAN instance view to configure mappings between a Layer 2 ring protocol instance and VLANs. This command applies to all ring protocols, facilitating configurations.
Configuration Impact
After you run the undo instance vlan command to delete mappings between a specified instance and VLANs, these VLANs will be remapped to instance 0.
If the
instance vlan command is run more than once, all configurations take effect.
