1. Such configurations enable the ring to block different links based on VLANs and achieve single-ring
load balancing.

Intersecting-ring load balancing
In an intersecting-ring network, you can also achieve load balancing by configuring multiple domains.
As shown in Figure 23, R
ing 1 is the primary ring and Ring 2 is the subring in both Domain 1 and
Domain 2. Domain 1 and Domain 2 are configured with different protected VLANs. Device A is
configured as the master node of Ring 1 in Domain 1. Device D is configured as the master node of Ring
1 in Domain 2. Device E is configured as the master node of Ring 2 in both Domain 1 and Domain 2.
However, different ports on Device E are blocked in Domain 1 and Domain 2. With the configurations,
you can enable traffic from different VLANs to travel over different paths in the subring and primary ring,
achieving intersecting-ring load balancing.
