VPLS ID	Identifier for identifying a BGP AD VSI on various PEs.
RD	Route Distinguisher, which is the same as the VPLS ID in the BGP AD VSI.
SAII	Source Attachment Individual Identifier, which is a local IP address used during negotiation on the creation of a PW in the BGP AD VSI.
TAII	Target Attachment Individual Identifier, which is a remote IP address used during negotiation on the creation of a PW in the BGP AD VSI.
