Intersecting-Ring Load Balancing Configuration Example - H3C S9500E Series Configuration Manual

Create RRPP domain 1, configure VLAN 4092 as the primary control VLAN of RRPP domain 1,
and configure VLANs mapped to MSTIs 0 through 47 as the protected VLANs of RRPP domain 1.
[DeviceE] rrpp domain 1
[DeviceE-rrpp-domain1] control-vlan 4092
[DeviceE-rrpp-domain1] protected-vlan reference-instance 0 to 47
Configure Device E as the master node of subring 2, with GigabitEthernet 3/0/1 as the primary
port and GigabitEthernet 3/0/2 as the secondary port, and enable ring 2.
[DeviceE-rrpp-domain1] ring 2 node-mode master primary-port gigabitethernet
3/0/1 secondary-port gigabitethernet 3/0/2 level 1
[DeviceE-rrpp-domain1] ring 2 enable
[DeviceE-rrpp-domain1] quit
Enable RRPP.
[DeviceE] rrpp enable
Verification
6.
After the configuration, you can use the display command to view RRPP configuration result on
each device.

Intersecting-ring load balancing configuration example

Networking requirements
•
Device A, Device B, Device C, Device D, and Device F constitute RRPP domain 1, and VLAN
100 is the primary control VLAN of the RRPP domain.
○
Device A is the master node of the primary ring Ring 1.
○
Device D is the transit node of the primary ring Ring 1.
○
Device F is the master node of the subring Ring 3.
○
Device C is the edge node of the subring Ring 3.
○
Device B is the assistant-edge node of the subring Ring 3.
•
Device A, Device B, Device C, Device D, and Device E constitute RRPP domain 2, and VLAN
105 is the primary control VLAN of the RRPP domain.
○
Device A is the master node of the primary ring Ring 1.
○
Device D is the transit node of the primary ring Ring 1.
○
Device E is the master node of the subring Ring 2.
○
Device C is the edge node of the subring Ring 2.
○
Device B is the assistant-edge node of the subring Ring 2.
•
Specify VLAN 10 as the protected VLAN of domain 1, and VLAN 20 as the protected VLAN
of domain 2, to achieve VLAN-based load balancing on the primary ring.
•
As the edge node and assistant-edge node of subring Ring 2 is the same as those of subring
Ring 3, and the two subrings have the same SRPTs, you can add subrings Ring 2 and Ring 3
to the RRPP ring group to reduce Edge-Hello traffic.
