Re: [j-nsp] The P2MP LSP story when using LDP for VPLS?
Yes, today P2MP can only be achieved with RSVP. Also, P2MP is thought for a different application than VPLS perhaps. VPLS is bidirectional any-to-any communication. P2MP is one-way from-on-to-many communication.

-Original Message- From: juniper-nsp-boun...@puck.nether.net [mailto:juniper-nsp- boun...@puck.nether.net] On Behalf Of Patrik Olsson Yes, today P2MP can only be achieved with RSVP. Also, P2MP is thought for a different application than VPLS perhaps. VPLS is bidirectional any-to-any communication. P2MP is one-way from-on-to-many communication. One can accomplish any-to-any communications with a series of one-to-many tunnels from each ingress PE to each egress PE in the VPN set. It's way more efficient than having to build a whole bunch of one-to-one tunnels for this type of application. It's also used in some of the newer mVPN approaches such as those that use selective or inclusive p2mp tunnels for building multicast distribution trees.
