This brief article explains how create a simple F/R Configuration.
Physical Topology:
Logical Topology:

Verification:
thanx for the help, it cleared some concepts of FR and easily configure FR Switch
you’re welcome
fantastic it cleared all the doubts in multipoint configuration
No need for manual frame-relay map, inverse arp is automatically enabled for IPv4 over FrameRelay. (sh frame map | i dynamic or Dynamic)
