Which of the following are correct statements about MPLS labels (Choose three)?

The correct answer is A. A series of labels from one LER to another LER represent a logical tunnel known as an LSP. B. Labels used for a LSP may be static but are usually signaled dynamically with an MPLS label C. Labels are locally significant to the MPLS router which means its possible for two routers on the LSP. See the full explanation below for the reasoning.
