Which statement represents the overall impact of convergence in a frame-mode MPLS network when there is a failure on a link that an LSP is using?

Which statement represents the overall impact of convergence in a frame-mode MPLS network when there is a failure on a link that an LSP is using?

A.
Overall convergence is not affected because, by default, frame-mode MPLS uses liberal retention mode.

B.
The LSPs must be rebuilt by the LDP, which minimally impacts convergence regardless of the number of LSPs.

C.
The LSPs must be rebuilt by the LDP, and the impact of convergence depends upon the number of LSPs using the failed link.

D.
The LSPs must be rebuilt along with the LFIB and LIB on each LSR on the path, which can dramatically impact convergence.
