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 both the SAP protection
and spoke SDP protection scenarios..
Figure 88: Example Configuration for Load Balancing Across Two Protected VPLS Spoke SDPs
Use the following CLI syntax to create a load balancing across two management VPLS instances:
CLI Syntax: config>service# sdp sdp-id mpls create
far-end ip-address
lsp lsp-name
no shutdown
CLI Syntax: vpls service-id customer customer-id [m-vpls] create
description description-string
mesh-sdp sdp-id:vc-id create
spoke-sdp sdp-id:vc-id create
stp

stp
no shutdown
Note: the STP path costs in each peer node should be reversed.
