What is the relationship between a Forwarding Equivalence Class (FEC) and the MPLS
label that a Label Switching Router (LSR) advertises for that FEC?
A.
An LSR assigns the same label to FECs with the same best next hop: labels remain
constant across the MPLS domain
B.
The LSR assigns a unique label to each FEC, but labels assigned by different LSRs do
not necessarily match.
C.
The LSR assigns a unique label to each FEC. and that label remains constant across the
MPLS domain
D.
An LSR assigns the same label to FECs with the same best next hop; labels assigned by
different LSRs do not necessarily match
