Which of the following are functions of the MPLS control plane in a router? (Choose two)
The MPLS (Multiprotocol Label Switching) control plane is responsible for label allocation and management as well as label signaling. Label allocation and management involve assigning labels to routes and managing those labels. Label signaling is the process by which label information is distributed between routers to establish the label-switched paths (LSPs). Label swapping, pushing a label, and routing lookups are part of the MPLS data plane, responsible for forwarding packets through the network based on labels received from the control plane.
The MPLS control plane uses: - Standard routing protocols to exchange information with other LSRs to build and maintain forwarding tables; and - Label distribution, or signaling protocols to communicate label binding information with other LSRs.
