# Create RRPP domain 1, configure VLAN 4092 as the primary control VLAN of RRPP domain 1, and
configure the VLANs mapped to MSTIs 0 through 32 as the protected VLANs of RRPP domain 1.

# Configure Device B as the transit node of primary ring 1, with GigabitEthernet1/0/1 as the primary port
and GigabitEthernet1/0/2 as the secondary port, and enable ring 1.

3) Perform the following configuration on Device C:
The configuration on Device C is similar to that on Device B and thus omitted here.
4) Perform the following configuration on Device D:
The configuration on Device D is similar to that on Device B and thus omitted here.
5) Verification
After the above configuration, you can use the display command to view RRPP configuration on each
device.

Networking requirements
z
Device A, Device B, Device C and Device D constitute RRPP domain 1, VLAN 4092 is the primary
control VLAN of RRPP domain 1, and RRPP domain 1 protects all the VLANs;
z
Device A, Device B, Device C and Device D constitute primary ring 1;
z
Device B, Device C and Device E constitute subring 2;
z
Device A is the master node of primary ring 1, GigabitEthernet 1/0/1 is the primary port and
GigabitEthernet 1/0/2 is the secondary port;
z
Device E is the master node of subring 2, GigabitEthernet 1/0/1 is the primary port and
GigabitEthernet 1/0/2 is the secondary port;
z
Device B is the transit node of primary ring 1 and the edge node of subring 2, and GigabitEthernet
1/0/3 is the edge port;
z
Device C is the transit node of primary ring 1 and the assistant-edge node of subring 1, and
GigabitEthernet 1/0/3 is the edge port;
z
Device D is the transit node of primary ring 1, GigabitEthernet 1/0/1 is the primary port and
GigabitEthernet 1/0/2 is the secondary port;
z
The timers of both the primary ring and the subring adopt the default value.
First, determine the primary ring and subring in an RRPP domain, node mode of a device on each
RRPP ring, and then perform the following configuration on a per-device basis:
z
Disable STP on all ports accessing RRPP rings on these devices and configure these ports to
permit the traffic of all VLANs to pass through.
z
Configure the 802.1p priority for trusted packets on ports accessing RRPP rings on each device.
z
Create an RRPP domain.
