Hi Edward, Thank you for the comments. I add l2vpn maillist in cc list. I agree with the application you proposed, and in order to improve the scalability of VPLS, P2MP PW multiplexed to HSMP LSP could be used for VPLS. Actually this is a good application case for P2MP PW with reverse path (section 4.4, draft-ietf-pwe3-p2mp-pw-00). We can add some description about this use case.
