MPLS supports both static and dynamic LSP establishment. Which of the following protocols cannot dynamically establish LSPs in MPLS TE scenarios? (Select all that apply)
InMPLS Traffic Engineering (TE),Label Switched Paths (LSPs)can be established:
Statically: Manual configuration.
Dynamically: Typically viaRSVP-TE.
Protocol roles:
RSVP-TE:Used to dynamically establish and signal TE LSPs→✅
OSPF / IS-IS: Act asIGP protocolsand provide TE-related link-state information (like bandwidth) butdo not establish LSPs themselves→❌
BGP: Used forroute advertisement, not forLSP setupin MPLS TE →❌
Correct answers: A, C, D
