Why do Cisco MPLS TE tunnels require a link-state routing protocol?
A) The link-state database provides segmentation by area, which improves the path-selection process.
B) The link-state database provides a data repository from which the tunnel endpoints can dynamically select a source ID.
C) Link-state routing protocols use SPF calculations that the tunnel endpoints leverage to implement the tunnel.
D) The tunnel endpoints use the link-state database to evaluate the entire topology and determine the best path.
