Michael,
The "no arp frame-relay" command does not stop the router from
sending inverse-ARP requests or replying to inverse-ARP requests. Any
book or practice lab that says that it does is incorrect.
The command doesn't have any effect on inverse-ARP whatsoever.
If you think about it, there isn't support for ARP in Frame Relay to
begin with so why would you ever need to disable it? Frame Relay
support inverse-ARP and not ARP.

Subject: Disabling Frame Relay ARP Question
Im working on a lab where Im told to not to use inverse arp. The
provided final configs have both no frame inverse-arp and no arp
frame-relay under the interface configuration.
Do I need both commands? It seems like either one would work if applied
to all frame relay interfaces.
no frame inverse-arp disables the router from responding to inverse
arp requests.
no arp frame-relay disables the router from sending out inverse arp
requests.
Also, can anyone give me a real world example of where you would use one
command over the other one?
