Scott,
Your suggestion will not work. The "protocol ip" option on the
end of the "frame-relay interface-dlci" command is used for auto-install
as it's the IP address to assign to the remote end during BootP. From
the DocCD:
<DocCD>
protocol ip ip-address
(Optional) Indicates the IP address of the main interface of a new
router or access server onto which a router configuration file is to be
automatically installed over a Frame Relay network. Use this option only
when this device will act as the BOOTP server for automatic installation
over Frame Relay.
</DocCD>
Lastly what isn't stated in the documentation is that the
"protocol ip" option is only available under a point-to-point
subinterface. Since it's a point-to-point subinterface, no layer 3 to
layer 2 mapping is ever required anyways. See below:
Rack2R2(config)#int s0/0

Depending on your IOS version, you can also use "frame-relay
interface-dlce
(#) protocol ip (ip#)" in order to map to the other side.

But other than that, PPPoFR would be something worth looking at.

Thanks, Bob.....They limit you in the lab to using 2 subinterfaces to do
this on R2 (one is already a point to point, which is working). They
state
"Do not use map statements on R2". Is there a way to accomplish this
using
a class map and map-lists? Or, could this be an error on the lab? I'll
was
going to try the sub interface on two point to points, but it didn't
look
right considering I only have one subnet.

Dave,
Seems to me that if your frame-relay interface is multipoint (physical
or
subif), then mapping is required (either static or dynamic). If both
static
and dynamic mapping is ruled out, then you must use point-to-point
subinterfaces. Does the scenario explicity rule out p-p subifs? Have
you
considered puttiing the same subnet on two p-p subifs?

Subject: Frame Question
I have a lab question that has a multipoint frame terminating at
R2 with
two DLCIs going to two different routers. You must disable
inverse
arp,
and must use sub-interfaces. The last catch on this is .....
You cannot
use the map statement. This makes it so you can only use the
frame-relay interface-dlci command. However, this won't work
for
mapping to the IP address at each location. Any ideas on how to
make
this one work? Everything on the doc cd for static mapping on a
multipoint requires map statements. Hmmmm.
