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
spoke-sdp sdp-id:vc-id create
stp
path-cost 
stp
no shutdown
This following output shows example configurations for load balancing across two protected 
VPLS spoke SDPs:
The configuration on ALA-A (SAS-M) is shown below.
