For Frame-Relay Point-to-point sub interfaces you do need the "Frame-relay
interface-dlci" command. Otherwise how would the DLCI get assigned to that
interface.
Here is how I understand it:
"Frame-Relay Interface-DLCI" assigns a DLCI to a particular interface. With
this command you are relying on INV-ARP to do the layer three to layer two
mapping for you. This is the only way that you can assign a DLCI to a
Point-to-Point sub interface.
"Frame-relay map" with this command you are statically mapping the layer
three protocol to layer two(the DLCI). You can't use this command on a
point-to-pont sub interface, but rather only on multipoint and the physical
frame relay interface. I recommend doing this on the lab and not trusting
INV-ARP.
As far as the "broadcast" statement after the map command, it is used for
enabling the forwarding of broadcast and multicast packets. This is needed
for the correct operation of some routing protocols.
Hope that helps,
JF

For point to point, theres no need for configuring DLCI's, MAP or Broadcast
statements.
