My bad, I looked closer at the directions and noticed that it said not
to use inverse arp. However, the R2 router was not in the list of
routers where it couldn't be used. So, the solution is to use the
frame-relay interface dlci command along with inverse arp. That one had
me thinking though. Thanks for everyone's help.

Hi all,
This is a very interesting scenario and I like the proposed
configuration.
However, isn't this config using dynamic arp to resolve the remote ip
address which, if so, violates the constraints of the original task?

Hi Dave,
Just labbed Amit's suggestion up. Note in config below that both VTs
have
the
same IP address. It is a hack, but it works. Not sure if this is the
solution for your lab, but it is one solution.
interface Serial0/0
description Determine Frame Interfaces based on requirement
no ip address
encapsulation frame-relay
frame-relay interface-dlci 102 ppp Virtual-Template102
frame-relay interface-dlci 103 ppp Virtual-Template103

That requires that you use ppp, correct? These are on the same subnet
and
I
only have a single ip address on the multipoint at R2.

Dave,
Amit's solution looks like the ticket. If you can create two Virtual Templates, each associated with a different PVC, then you will not need mapping, since the VT is point-to-point. Addressing two VTs with the same subnet/IP could be an issue, though.

Does that require that you use PPP. How does this solve the mapping issue?

If you are using two different subnets on both subints then you can use virtual templates and bind each VT to frame-relay interface-dlci command.
