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 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 spokes.
Load balancing can be achieved in both the SAP protection and spoke SDP protection scenarios.
