Multi-stream S-PMSI is configured in the context of an auto-discovery default (that is, NG-MVPN). It supports all existing per-mLDP/RSVP-TE P2MP S-PMSI tunnel functionality for multi-stream S-PMSI LSP templates (RSVP-TE P-instance).
Notes:
Per-multicast group statistics are not available for multi-stream S-PMSIs on S-PMSI level.
GRE tunnels are not supported for multi-stream S-PMSI.
