Which of the following are control plane protocols used within a service provider MPLS network? (Choose two.)
Which of the following are control plane protocols used within a service provider MPLS network? (Choose two.)
Control plane protocols are responsible for the operations and signaling within a network, including in an MPLS (Multiprotocol Label Switching) environment. The correct answers from the given options are: RSVP (Resource Reservation Protocol) and LDP (Label Distribution Protocol). RSVP is used for reserving resources and as a signaling protocol in MPLS Traffic Engineering (TE). LDP is used for label distribution in MPLS, enabling routers to learn the labels for forwarding traffic. Options OAM (Operations, Administration, and Maintenance) and SNMP (Simple Network Management Protocol) are related to management and monitoring rather than control plane operations. Targeted LDP is a specialized use of LDP, so it is not considered a distinct protocol in this context.
B & E are correct
Control plane protocols are responsible for the operations and signaling within a network, including in an MPLS (Multiprotocol Label Switching) environment. The correct answers from the given options are: B. RSVP (Resource Reservation Protocol) E. LDP (Label Distribution Protocol) Explanation: RSVP: It's used for reserving resources and is also employed as a signaling protocol in MPLS Traffic Engineering (TE). LDP: This protocol is used for label distribution in MPLS, enabling routers to learn the labels to use for forwarding traffic. Option C (Targeted LDP) is a specialized use of LDP, so it's related but not a distinct protocol in this context. Options A (OAM - Operations, Administration, and Maintenance) and D (SNMP - Simple Network Management Protocol) are not typically classified as control plane protocols within the context of an MPLS network, as they are more related to management and monitoring.
Given anser is correct. There are two standardized protocols for managing MPLS paths: the Label Distribution Protocol (LDP) and RSVP-TE, an extension of the Resource Reservation Protocol (RSVP) for traffic engineering. Furthermore, there exist extensions of the Border Gateway Protocol (BGP) that can be used to manage an MPLS path.
