Frame Relay Subinterfaces

Hello

 

I working with Workbook 1, with the frame-relay section, (2.5) I have a doubt when we used multipoint intefaces with static map is necessary to used diferent DLCI for each router in the network?

 

Thanks

    In this scenario,  we are asked to modify the previous 2.4.  We know each router has more than one DLCI (or FR connections) by the dynamic mappings  that already exist.   We are asked to change those existing dynamic mappings to static mappings.

     

    The very next exercise (2.6  Hub & Spoke)  says to only use the DLCI's in the diagram.  This will be the norm for the workbook(s) moving forward.  Hub and Spoke Frame Relay.

  • Without static mapping and given the inverse-arp is disabled, the IP packets won't know which DLCI to use for forwarding. Just think about multipoint has "multi-exit" and we define which DLCI to use to reach specific destination.

  • I would recommend the WB3 labs also, they will test you on a lot of differing frame-relay scenarios.

    This document may also help with further explanations and examples,

    Of this link may help to give you a broader overview/understanding of frame-relay.
