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;

Device A, Device B, Device C and Device D constitute primary ring 1, and Device B, Device C and

Device E constitute subring 2;

Device A is the master node of primary ring 1, GigabitEthernet 2/0/1 is the primary port and

GigabitEthernet 2/0/2 is the secondary port;

Device E is the master node of subring 2, GigabitEthernet 2/0/1 is the primary port and

GigabitEthernet 2/0/2 is the secondary port;

Device B is the transit node of primary ring 1 and the edge node of subring 2, and GigabitEthernet

2/0/3 is the edge port;

Device C is the transit node of primary ring 1 and the assistant-edge node of subring 1, and

GigabitEthernet 2/0/3 is the edge port;

Device D is the transit node of primary ring 1, GigabitEthernet 2/0/1 is the primary port and

GigabitEthernet 2/0/2 is the secondary port.

Configuration procedure

1) Configuration on Device A

# Configure the suppression time of physical-link-state changes on GigabitEthernet 2/0/1 and

GigabitEthernet 2/0/2 as zero, disable STP, configure the two ports as trunk ports, and assign them to

all VLANs.
