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 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.
To configure protected VLANs:
To do...
Enter system view
Enter MST region view
Configure the VLAN-to-
instance mapping table
Activate MST region
configuration manually
Display the currently activated
configuration information of
the MST region
Return to system view
Enter RRPP domain view
Configure protected VLANs
for the RRPP domain
When configuring load balancing, you must configure different protected VLANs for different RRPP
domains.
For more information about the stp region-configuration, instance, vlan-mapping modulo, active region-
configuration, and display stp region-configuration commands, see Layer 2—LAN Switching Command
Reference.
Use the command...
system-view
stp region-configuration
instance instance-id vlan vlan-list
vlan-mapping modulo modulo
active region-configuration
display stp region-configuration [
| { begin | exclude | include }
regular-expression ]
quit
rrpp domain domain-id
protected-vlan reference-instance
instance-id-list
64
Remarks
Not required if the device works
in PVST mode.
Optional
Use either command.
All VLANs in an MST region are
mapped to MSTI 0 (the CIST) by
default.
Not required if the device works
in PVST mode.
