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