Know how to disable inarp and put in map statments. My question is why
should we disable inarp and not rely on dynamic mappings?
thanks

Use "no fram inv" every FR interfaces except point-to-point. i.e. Do not
rely on dynamic mappings even for IPX.
Never Give Up,

Hi,
I have been confused by frame-relay inverse-arp and arp frame-relay. For
example, suppose that Router R1, R2, R3, R4 fully messed to configure IP.
Only R1 can use subinterfaces, say s0.1 point-to-point (to R4), s0.2
multipoint (to R2 and R3). The requirement is that on R4 can not use
subinterface and map. I also don't want to see R2,R3's IP address on R4, and
on R2,R3 can't see R4's IP address. (Show Frame-relay map"
With the following configuration, I reloaded the Routers, but still can't
solve the problem.
(1)on R4 cannot see R2, R3's IP address? Even though on R2, R3, I
configured "no frame-relay inverse" and "no arp frame-relay".
(2)On R4, whether or not put "no arp frame-relay", on R2,R3 can still see
R4's IP address.
