Verify the configuration:Use the display command to view RRPP configuration and operational information on each device.Intersecting-ring load balancing configuration exampleNetworking requirementsAs shown in Figure 21,• Device A, Device B, Device C, Device D, and Device F form RRPP domain 1, and VLAN 100 is theprimary 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 Ring 1; Device F is the master node of the subring Ring 3; Device Cis 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 form RRPP domain 2, and VLAN 105 is theprimary 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 Ring 1; Device E is the master node of the subring Ring 2; Device Cis the edge node of the subring Ring 2; Device B is the assistant-edge node of the subring Ring 2.• Specify VLAN 1 as the protected VLAN of domain 1 and VLAN 2 the protected VLAN of domain2. You can implement VLAN-based load balancing on Ring 1.• Because the edge node and assistant-edge node of Ring 2 are the same as those of Ring 3 and thetwo subrings have the same SRPTs, you can add Ring 2 and Ring 3 to the RRPP ring group to reduceEdge-Hello traffic.
