Selected Answer: A
The headend router sends one RSVP path message to each destination. The tailend router replies with a RESV message. The Label Forwarding Information Base (LFIB) is populated using the RSVP labels allocated by the RESV messages. https://www.cisco.com/c/en/us/td/docs/routers/asr920/configuration/guide/mpls/17-1-1/b-mp-te-path-setup-xe-17-1-asr920/m_mp-te-p2mp.html
