Frame Relay Simulation Question

I'm trying to simulate a network through a frame relay cloud with my
Cisco CCNA network simulator. How do I keep the WAN links in the same
network on the other side of the FR cloud?  Must I use NAT?

For example, if I have local_rtr S0 with an ip of 192.168.101.1 going
into the FR cloud, and I want the remote_rtr (off the other side of the
FR cloud) to be 192.168.101.2 how do I do this?  

Thanks

Your End:  192.168.101.1
Remote End: 192.168.101.2

!  Your End
interface serial0
no ip address
encapsulation frame-relay ietf
!
interface serial0.1 point-to-point
ip address 192.168.101.1 255.255.255.252
frame-relay interface-dlci <whatever> ietf
!


! Remote End
interface serial0
no ip address
encapsulation frame-relay ietf
!
interface serial0.1 point-to-point
ip address 192.168.101.2 255.255.255.252
frame-relay interface-dlci <whatever> ietf

In this situation, there is no need to use subinterfaces.  In fact, if you
don't, then the dlci's can be autodiscovered.  The config is as easy as
this:

local:

interface serial
encapsulation frame-relay ietf
ip address 192.168.101.1 255.255.255.252

remote:

interface serial0
encapsulation frame-relay ietf
ip address 192.168.101.2 255.255.255.252

 What if the circuit is point-to-point and the remote end has you built to a
 Sub-Interface?

How the other end is configured is not really of consequence to you.  You
are configuring the router from *your* perspective.  If this is a hub/spoke
config, you can have subinterfaces at the central location and single
interfaces at the remotes. Of course, you do need to make sure that your ip
is on the right subnet.

Actually, you can even have a single interface at the central location in a
hub and spoke / point to multipoint environment, it just limits your control
somewhat.  If there is no driving reason, this config saves time during
config and maintenance since all pvcs will be autodiscovered.  All sites can
be on the same subnet when configured as a single interface.  When you want
to add a new site, you just config the remote router and drop it in, nothing
to do at the central location.
