among the problems with MPLS The Tag Distribution Protocol (TDP) or Label Distribution Protocol (LDP) session does not start.
The TDP or LDP session starts, but the labels are not allocated or distributed.
The labels are allocated and distributed, but the forwarded packets are not labeled.
The large IP packets are not propagated across the MPLS backbone, even though they were successfully propagated across the pure IP backbone.
My question is, what is at the root of each problem in a specific way?!
please help me i really need to understand why this problem that a person of good faith can bring regards to my question
