P2MP LSP's are totally applicable in use with VPLS. Broadcast frames, unknown destination unicast, and multicast (although in the case of Ethernet, kinda like broadcast) need to get sent to all or multiple PE's. My understanding is that a P2MP LSP will duplicate the encap'ed frames to use core bandwidth more efficiently. --j _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
