Configuring Load Balancing with Management VPLS
With the concept of management VPLS, it is possible to load balance the user VPLS services
across the two protecting nodes. This is done by creating two management VPLS instances, where
both instances have different active QinQ spokes (by changing the STP path-cost). When different
user VPLS services are associated with either the two management VPLS services, the traffic will
be split across the two QinQ spokes. Load balancing can be achieved in SAP protection scenarios.

Note: the STP path costs in each peer node should be reversed.
