["UTTARO, JAMES" <[e-mail]>]

The assumption being that the majority of customer are building more than a two or three point VPLS domain.. My experience does not indicate that VPLS is a service that supports many endpoints per VPLS VPN. Anyway why not simply use EVPN for this purpose? There are no PWs,  traffic traverses the same LSPs used for any other service.

Hi,

Service providers are facing a heavy provisioning overhead in VPLS since a mass of PWs need to be maintained. If PEs can use Customer VLAN ID as a service discriminator in VPLS, the required number of PWs will be greatly reduced. Therefore, the provision overhead can be significantly relieved.

Authors compose the draft to justify the solutions on recognizing Customer VLAN IDs in VPLS. We wish to receive your comments and suggestions. 

Thanks,
Mingui
