Ok, now you all got me interested.
#1) From what I'm reading, you are saying that if you create a FR lab and
just place the DLCI map commands on the frame switch for the remote ends, and
you have the LMI set right, then the remotes will automatically learn their
DLCIs through LMI?
#2) Would this also work in a real environment concerning telco assigning you
DLCI numbers? What I'm saying is, after the telco gives you the DLCIs for
your DTE interfaces (remote ends) usually you would go in and configure them.
If you didn't bother to go and configure them, would your remote ends
automatically learn them from the FR switch somewhere in the telco's network
through LMI???
