3. Configure Device C.
The configuration on Device C is similar to that on Device B so detailed steps are not shown.
4. Configure Device D.
The configuration on Device D is similar to that on Device B so detailed steps are not shown.
5. Verify the configuration.
Use the display command to view RRPP configuration and operational information on each device.

Networking requirements
As shown in Figure 21,
Device A, Device B, Device C, Device D, and Device E form RRPP domain 1. VLAN 4092 is the
primary control VLAN of RRPP domain 1, and RRPP domain 1 protects VLANs 1 through 30.
Device A, Device B, Device C and Device D form primary ring 1, and Device B, Device C and
Device E form subring 2.
Device A is the master node of primary ring 1, with GigabitEthernet 1/0/1 as the primary port and
GigabitEthernet 1/0/2 the secondary port.
Device E is the master node of subring 2, with GigabitEthernet 1/0/1 as the primary port and
GigabitEthernet 1/0/2 the secondary port.
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.
