I thought rule "[B] Do not use frame-relay map CLI" is for both router R1 &
R2?
GAURAV, can you clarify?
If its true, then the only solution I could think of is PPPoFR because after
all, you are using the physical interface for frame relay. They did not
specify that you are not allowed to introduce new virtual interface.
Does use physical interface mean that you have to configure the IP on it? Or
just mean you must not use subs? I always thought it's the later.
Kind Regards,
KG

You are not right, pppofr breaks 1 (use physical).
In your example R2 should not sends iARP, but R1 can, once R1 sends iARP
at the same time, it provides the remote system (R2) with the Layer 3
address of the local system (R1).
Solution:
R1
interface Serial0/0
ip address 10.0.0.1 255.255.255.0
encapsulation frame-relay
R1#show frame-relay map
Serial0/0 (up): ip 10.0.0.2 dlci 102(0x66,0x1860), dynamic,
broadcast,, status defined, active
R2
interface Serial0/0
ip address 10.0.0.2 255.255.255.0
encapsulation frame-relay
R2#show frame-relay map
Serial0/0 (up): ip 10.0.0.1 dlci 201(0xC9,0x3090), dynamic,
broadcast,, status defined, active
