Here is what the doc CD says about this command.....it "Enables ARP over a
Frame Relay encapsulated interface". Encapsulated interface on frame-relay
will need a little explanation.
Dave
arp (interface)
To control the interface-specific handling of IP address resolution into
48-bit Ethernet, FDDI, Frame Relay, and Token Ring hardware addresses, use the
arp interface configuration command. To disable an encapsulation type, use the
no form of this command.
arp {arpa | frame-relay | probe | snap}
no arp {arpa | frame-relay | probe | snap}
Syntax Description
arpa
Standard Ethernet-style Address Resolution Protocol (ARP) (RFC 826).
frame-relay
Enables ARP over a Frame Relay encapsulated interface.
probe
HP Probe protocol for IEEE-802.3 networks.
snap
ARP packets conforming to RFC 1042.

I think no arp frame-relay will be used in ATM-Frame relay
internetworking .
In Plain Vanila Frame-Relay networks it has not meaning .
Thanks and Regards
