I'm a voice guy that is learning the data side and have a question about frame relay DLCI numbers. I'm trying to determine without a doubt if the DLCI number stays the same along the path to the destination or if it changes/could change from node to node.
My logic and a basic understanding of what I read in numerous books and results of online searches tells me it stays the same for the duration of the virtual circuit being established. I do understand that each end in a 'conversation' uses its own designated DLCI, but I can't seem to find a definitive answer on whether this number stays the same all the way to the other end.
I find many references saying the identifier only has local significance. I just don't know if this means local to each link in the path or to each originating end. I appreciate any assistance in clearing this up for me.
