From an implementation and forwarding plane/replication perspective, it would be better to have all three types use the same P2MP PW. With current implementations which support P2MP RSVP tunnels for these types of traffic, they cover all three.

BTW, any feedback on the following two questions: - whether there is a need to optimise Ethernet broadcast/multicast traffic when using VPLS. - whether carriers with LDP-VPLS (RFC 4762) would like to consider a solution that does not require BGP. Thanks, Simon

Simon,
your ID provides a solution for the efficient propagation of Ethernet broadcast and multicast ethernet frames. Is there any reason, why you have not mentioned the distribution of unknown unicasts via this P2MP tree (the required MAC learning by the leaf is mentioned in your ID) ? Or is it implicit by your understanding of "broadcast"?

Subject: [PWE3] new draft - Extension to LDP-VPLS for Ethernet broadcast &multicast
Hi L2VPN & PWE3 workgroups, There is a new internet draft - Extension to LDP-VPLS for Ethernet broadcast and multicast ( http://tools.ietf.org/html/draft-delord-l2vpn-ldp-vpls-broadcast-exten-00) .
Our proposed approach relies on a simple extension to LDP-VPLS to optimise Ethernet Multicast/Broadcast traffic within a carrier's network. It allows the use of unidirectional point-to-multipoint PseudoWires to minimise payload frame duplication on physical links.
The authors would like to solicit comments from the workgroups. In particular, - whether there is a need to optimise Ethernet broadcast/multicast traffic when using VPLS. - whether carriers with LDP-VPLS (RFC 4762) would like to consider a solution that does not require BGP.
Thanks a lot.
Simon
