Single ring configuration example

As shown in Figure 20:

• Device A, Device B, Device C, and Device D form RRPP domain 1. Specify the primary control VLAN of RRPP domain 1 as VLAN 4092. Specify the protected VLANs of RRPP domain 1 as VLANs 1 through 30.

• Device A, Device B, Device C, and Device D form primary ring 1.

• Specify Device A as the master node of primary ring 1, GigabitEthernet 1/0/1 as the primary port, and GigabitEthernet 1/0/2 as the secondary port.

• Specify Device B, Device C, and Device D as the transit nodes of primary ring 1. Specify GigabitEthernet 1/0/1 as the primary port and GigabitEthernet 1/0/2 as the secondary port on Device B, Device C, and Device D.

1. Configure Device A:

   # Create VLANs 1 through 30.

   <DeviceA> system-view
   [DeviceA] vlan 1 to 30
   

   # Map these VLANs to MSTI 1.

   [DeviceA] stp region-configuration
   [DeviceA-mst-region] instance 1 vlan 1 to 30
   

   # 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
   

   # Disable the spanning tree feature on the port.

   [DeviceA-GigabitEthernet1/0/1] undo stp enable
   

   # Configure the port as a trunk port.

   [DeviceA-GigabitEthernet1/0/1] port link-type trunk
   

   # Assign the port to VLANs 1 through 30.

   [DeviceA-GigabitEthernet1/0/1] port trunk permit vlan 1 to 30
   [DeviceA-GigabitEthernet1/0/1] quit
   

   # Configure GigabitEthernet 1/0/2 in the same way GigabitEthernet 1/0/1 is configured.

   [DeviceA] interface gigabitethernet 1/0/2

   [DeviceA-GigabitEthernet1/0/2] port link-type trunk
   [DeviceA-GigabitEthernet1/0/2] port trunk permit vlan 1 to 30

   # Create RRPP domain 1.

   [DeviceA] rrpp domain 1
   

   # Configure VLAN 4092 as the primary control VLAN of RRPP domain 1.

   [DeviceA-rrpp-domain1] control-vlan 4092
   

   # Configure the VLANs mapped to MSTI 1 as the protected VLANs of RRPP domain 1.

   [DeviceA-rrpp-domain1] protected-vlan reference-instance 1
   

   # Configure Device A as the master node of primary ring 1, with GigabitEthernet 1/0/1 as the primary port and GigabitEthernet 1/0/2 as the secondary port. Enable ring 1.

   [DeviceA-rrpp-domain1] ring 1 node-mode master primary-port gigabitethernet 1/0/1 secondary-port gigabitethernet 1/0/2 level 0
   [DeviceA-rrpp-domain1] ring 1 enable
   [DeviceA-rrpp-domain1] quit
   

   # Enable RRPP.

   [DeviceA] rrpp enable
   

2. Configure Device B:

   # Create VLANs 1 through 30.

   <DeviceB> system-view
   [DeviceB] vlan 1 to 30
   

   # Map these VLANs to MSTI 1.

   [DeviceB] stp region-configuration
   [DeviceB-mst-region] instance 1 vlan 1 to 30
   

   # Activate the MST region configuration.

   [DeviceB-mst-region] active region-configuration
   [DeviceB-mst-region] quit
   

   # Set the physical state change suppression interval to 0 seconds on GigabitEthernet 1/0/1.

   [DeviceB] interface gigabitethernet 1/0/1
   [DeviceB-GigabitEthernet1/0/1] link-delay 0
   

   # Disable the spanning tree feature on the port.

   [DeviceB-GigabitEthernet1/0/1] undo stp enable
   

   # Configure the port as a trunk port.

   [DeviceB-GigabitEthernet1/0/1] port link-type trunk
   

   # Assign the port to VLANs 1 through 30.

   [DeviceB-GigabitEthernet1/0/1] port trunk permit vlan 1 to 30
   [DeviceB-GigabitEthernet1/0/1] quit
   

   # Configure GigabitEthernet 1/0/2 in the same way GigabitEthernet 1/0/1 is configured.

   [DeviceB] interface gigabitethernet 1/0/2
   [DeviceB-GigabitEthernet1/0/2] link-delay 0
   [DeviceB-GigabitEthernet1/0/2] undo stp enable
   [DeviceB-GigabitEthernet1/0/2] port link-type trunk
   [DeviceB-GigabitEthernet1/0/2] port trunk permit vlan 1 to 30
   [DeviceB-GigabitEthernet1/0/2] quit
   

   # Create RRPP domain 1.

   [DeviceB] rrpp domain 1
   

   # Configure VLAN 4092 as the primary control VLAN of RRPP domain 1.

   [DeviceB-rrpp-domain1] control-vlan 4092
   

   # Configure the VLANs mapped to MSTI 1 as the protected VLANs of RRPP domain 1.

   [DeviceB-rrpp-domain1] protected-vlan reference-instance 1
   

   # Configure Device B as the transit node of primary ring 1, with GigabitEthernet 1/0/1 as the primary port and GigabitEthernet 1/0/2 as the secondary port. Enable ring 1.

   [DeviceB-rrpp-domain1] ring 1 node-mode transit primary-port gigabitethernet 1/0/1 secondary-port gigabitethernet 1/0/2 level 0
   [DeviceB-rrpp-domain1] ring 1 enable
   [DeviceB-rrpp-domain1] quit
   

   # Enable RRPP.

   [DeviceB] rrpp enable
   

3. Configure Device C:

   Configure Device C in the same way Device B is configured.

4. Configure Device D:

   Configure Device D in the same way Device B is configured.
