  Initially, all links along the path R1-R2-R4-R6 have 400Mbps unreserved bandwidth and all links along the path R1-R3-R5-R6 have 800Mbps unreserved bandwidth. Shared Explicit reservation style is used and Make-Before-Break is enabled. Both fully loose LSPs have been signaled as shown. Later, the configured bandwidth for LSP-1 is changed to 400Mbps. Which of the following is TRUE?

  A. After a new path for LSP-1 is established on R1-R3-R5-R6, the old path is torn down.
  B. After the old path for LSP-1 is torn down, the new path is established on R1-R3-R5-R6.
  C. LSP-1 will stay on R1-R2-R4-R6 because there is enough bandwidth on the existing path.
  D. LSP-1 will be torn down because CSPF fails to find a new path.
  C. LSP-1 will stay on R1-R2-R4-R6 because there is enough bandwidth on the existing path.
