You are configuring a VPLS spoke termination to a VPRN on an Nokia 7750 SR. If LDP is used for all transport tunnels, what type of sessions are established by the VPRN PE router that is configured with the spoke termination?

  1. T-LDP and LDP sessions with the other VPRN PE routers and the VPLS PE router
  2. T-LDP sessions with the other VPRN PE routers and the VPLS PE router
  3. LDP sessions with the other VPRN PE routers and the VPLS PE router
  4. LDP sessions with the other VPRN PE routers, and both T-LDP and LDP sessions with the VPLS PE router
  5. T-LDP and LDP sessions with the other VPRN PE routers and LDP sessions with the VPLS PE router
