You can view that RRPP is enabled on PE1. In domain 1, VLAN 5 is the major control VLAN,
VLAN 6 is the sub-control VLAN, Instance1 is the protected VLAN, and PE1 is the master node
in major ring 1 with the primary interface and secondary interface respectively as
GigabitEthernet 1/0/2 and GigabitEthernet 1/0/3.

You can view that in domain 1, VLAN 5 is the major control VLAN, VLAN 6 is the sub-control
VLAN, Instance1 is the protected VLAN, and PE1 is the master node in major ring 1 with the
primary interface and secondary interface respectively as GigabitEthernet 1/0/2 and

Step 3 Configure the Layer 2 forwarding function on the CE, LSW1 to LSW3 and PE1 to PE4.
The configuration details are not mentioned here. For details, see configuration files in this
example.
Step 4 Verify the configuration.
After the previous configurations, run the following commands to verify the configuration after
the network is stable. Take LSW1 as an example.
l Run the shutdown command on GE 1/0/1 on LSW2 to simulate an interface fault, and then
run the display sep interface command on LSW3 to check whether the status of GE 1/0/2
changes from blocked to forwarding.
