Intersecting-ring load balancing
In an intersecting-ring network, you can also achieve load balancing by configuring multiple
domains.
As shown in
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.
