Configuring Load Balancing With Management Vpls - Alcatel-Lucent 7750 SR OS Service Manual

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.

Figure 4: Example Configuration for Loadbalancing 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
CLI Syntax: vpls service-id customer customer-id [m-vpls] create
