Configuration procedure
To configure control VLANs:
Ste

Command
1. Enter system view.
system-view
2. Enter RRPP domain view.
rrpp domain domain-id
3. Configure the primary control VLAN for the RRPP
domain.
control-vlan vlan-id
Configuring protected VLANs
Before configuring RRPP rings in an RRPP domain, configure the same protected VLANs for all nodes in
the RRPP domain first. All VLANs that the RRPP ports are assigned to should be protected by the RRPP
domains.
You can configure protected VLANs through referencing Multiple Spanning Tree Instances (MSTIs).
Before configuring protected VLANs, configure the mappings between MSTIs and the VLANs to be
protected. (A device working in PVST mode automatically maps VLANs to MSTIs.) For more information
about MSTIs and PVST, see Layer 2—LAN Switching Configuration Guide.
Perform this configuration on all nodes in the RRPP domain to be configured.

Command Remarks
1. Enter system view.
system-view N/A
2. Enter MST region view.
stp region-configuration
Not required if the device is
operating in PVST mode.
For more information about the
command, see Layer 2—LAN
Switching Command Reference.
3. Configure the
VLAN-to-instance mapping
table.
Approach 1:
instance instance-id vlan vlan-list
Approach 2:
vlan-mapping modulo modulo
Optional.
Use either approach.
All VLANs in an MST region are
mapped to MSTI 0 (the CIST) by
default.
Not required if the device is
operating in PVST mode.
For more information about the
commands, see Layer 2—LAN
Switching Command Reference.
4. Activate MST region
configuration manually.
active region-configuration
Not required if the device is
operating in PVST mode.

command, see Layer 2—LAN
Switching Command Reference.
