Configuring Single-Domain Intersecting Ring Topology - H3C LS-3100-52P-OVS-H3 Operation Manual

# 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.
[DeviceB] rrpp domain 1
[DeviceB-rrpp-domain1] control-vlan 4092
[DeviceB-rrpp-domain1] protected-vlan reference-instance 0 to 32
# 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.
[DeviceB-rrpp-domain1]
secondary-port gigabitethernet 1/0/2 level 0
[DeviceB-rrpp-domain1] ring 1 enable
[DeviceB-rrpp-domain1] quit
# Enable RRPP.
[DeviceB] rrpp enable
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.

Configuring Single-Domain Intersecting Ring Topology

Networking requirements
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;
Device B, Device C and Device E constitute subring 2;
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;
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;
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;
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;
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;
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:
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.
Configure the 802.1p priority for trusted packets on ports accessing RRPP rings on each device.
Create an RRPP domain.
