Device A, Device B, Device C, Device D, and Device F form RRPP domain 1. VLAN 100 is the
•
primary control VLAN of the RRPP domain. Device A is the master node of the primary ring, Ring 1.
Device D is the transit node of Ring 1. Device F is the master node of the subring Ring 3. Device C
is the edge node of the subring Ring 3. Device B is the assistant edge node of the subring Ring 3.
• Device A, Device B, Device C, Device D, and Device E form RRPP domain 2. VLAN 105 is the
primary control VLAN of the RRPP domain. Device A is the master node of the primary ring, Ring 1.
Device D is the transit node of Ring 1. Device E is the master node of the subring Ring 2. Device C
is the edge node of the subring Ring 2. Device B is the assistant edge node of the subring Ring 2.
Specify VLAN 1 1 as the protected VLAN of domain 1, and VLAN 12 the protected VLAN of domain
•
2. You can implement VLAN-based load balancing on Ring 1.
Ring 2 and Ring 3 have the same edge node and assistant edge node, and the two subrings have
•
the same SRPTs. You can add Ring 2 and Ring 3 to an RRPP ring group to reduce Edge-Hello traffic.

Configuration procedure
1. Configure Device A:
# Create VLANs 11 and 12.
<DeviceA> system-view
[DeviceA] vlan 11 to 12
# Map VLAN 11 to MSTI 1 and VLAN 12 to MSTI 2.
[DeviceA] stp region-configuration
[DeviceA-mst-region] instance 1 vlan 11
[DeviceA-mst-region] instance 2 vlan 12
# Activate the MST region configuration.
[DeviceA-mst-region] active region-configuration
[DeviceA-mst-region] quit
# Set the physical state change suppression interval to 0 seconds on GigabitEthernet 1/0/1.
[DeviceA] interface gigabitethernet 1/0/1
[DeviceA-GigabitEthernet1/0/1] link-delay 0
