How to configure Frame-Relay Point-to-Multipoint

Hello Sergei

There are several ways to get a Frame Relay PVC working correctly. One is to use the frame-relay interface-dlci 102 command. However, this would not apply here as it is only used on subinterfaces. It is not common to use, although it does have its uses. When applied, it will assign a DLCI to the subinterface. When the subinterface already has a DLCI assigned and an IP address has been configured on it, Inverse-ARP requests can now be sent to acquire the IP addresses of the neighbor devices.

Alternatively, the command used on the subinterfaces in the example in the lesson is the frame-relay map ip command. This command actually disables Inverse ARP and statically corresponds the IP addresses with the DLCIs.

Without any of these settings, on the physical interface, it is necessary to apply the frame-relay map ip command. So yes indeed you are correct that this must be implemented, and it has not in the lesson. I will let Rene know to make the appropriate adjustments.

Thanks for pointing it out!
