Point-to-Multipoint RSVP-TE LSP as inclusive or selective provider tunnel is available with BGP NG-MVPN only. P2MP RSVP-TE LSP is dynamically setup from root node on auto discovery of leaf PE nodes that are participating in multicast VPN. Each RSVP-TE I-PMSI or S-PMSI LSP can be used with a single MVPN instance only.
RSVP-TE LSP template must be defined (see 7450 ESS, 7750 SR, 7950 XRS, and VSR MPLS Guide) and bound to MVPN as inclusive or selective (S-PMSI is for efficient data distribution and is optional) provider tunnel to dynamically initiate P2MP LSP to the leaf PE nodes learned via NG-MVPN auto-discovery signaling. Each P2MP LSP S2L is signaled based on parameters defined in LSP template.
