Went through the frame-relay labs today. I have never used frame-relay in real life so although it wasn’t very difficult to configure I think I need to go through some videos and documentation to understand the details of inverse ARP and LMI. I know that LMI tells the DTE about the PVC’s available (DLCI’s) and that inverse ARP or static mappings is needed for the layer 3 to layer 2 resolution. I just need to work out which combos are available and how the DTE knows when using inverse ARP which DLCI to use when sending traffic out.
