Folks,
Can I have multipoint frame relay at the hub and point to point sub interfaces at the spoke? will it work?

Yes, it will work.
Hub
Rack1R1#sh run int s1/0
Building configuration...
Current configuration : 242 bytes

frame-relay map ip 192.168.123.2 102 broadcast

Spokes:

Edison,
Will this work if you had a multipoint subinterface at the hub instead of a physical interface?

Hi
I think it doesnt make any difference if u r going with this setup.
Thanks

You can work the way you want, only the L2 - L3 mappings should be perfect.

multipoint subinterface has the same behavior as a physical main interface, the only difference is that you can have multiple multipoint subinterfaces while you can only have one physical interface.
