I think in lab we will be instruct to use "frame-relay inter dlce xxx " as
QoS is in and to apply it we need this command
to apply to VCs.... without this QoS cant be applied on it. Acutually this
command also use inverse-arp the difference is
that by default all the dlci is given to the physical interface to
distingush it we use it on sub interface..... and i also
agree that there is no magic in it. I like this command more then maping
