Frame-Relay PPP Subinterfaces Configuration

Anyone have experience with Cisco Packet Tracer?

I have the FR-S1 (frame-relay cloud) configured this way:
S0 - DLCI 17 - R8
S1 - DLCI 18 - R7
S2 - DLCI 19 - R10

However, I can only map Serial0 - Serial1, Serial0 - Serial2, or Serial1 - Serial2, I can't assign S0 - S1 and S0 - S2 at the same time

That being said, R8 cannot ping R7, and I don't know why. They're on the same subnet. They have static mapping. If I were to assign Serial0 - Serial1 on the Frame-Relay switch, those two can ping each other (after taking static mapping off). However, since I can't assign Serial0 to Serial1 and Serial2, I didn't assign any interfaces to any interfaces on the frame-relay switch (this is why I used static mapping).

I know this sounds confusing, but I'm not sure how to get this to work >_<. I've been going well with Frame-Relay on all the practice tests I've had and even while studying, but when it comes to configuring it in Packet Tracer, it gets weird.

    You'll need to set this up as hub-and-spoke. PT is very limited. Create sub-interfaces on one of your routers, then you can set the mapping within the FR cloud.

    S0.1 -> S1
    S0.2 -> S2

    Thanks for that thread. With the Frame Relay swtich, there's no CLI, and there's no option to select subinterfaces. I see that one of the guys there too also said PT is very limited when it comes to Frame Relay... Blah >_< Is there another simulation software that works better than Packet Tracer that you know of?

    Thanks for your help so far.

    GNS3 is what I was using prior to purchasing lab gear.

    And I meant to create sub-interfaces on your routers then select them in the cloud. I am on my phone at the moment, otherwise I would send you some screen caps.

    yeah I'm mobile too. I was able to create the subinterfaces on the router, but there wasn't any way to select them on the frame relay switch. I can only specify the DLCI and name

    Try this:

    Wow, this explained everything. It seems as though I was missing the 2 PVCs between R8 and the frame relay switch. It looks like I was trying to use a multipoint interface. Got everything working. Thank you a BUNCH!

    Btw, how would you create a Frame Relay mesh network in Packet Tracer? Is that possible?

    See post #6 above, Youtube has several tutorials dealing with Frame Relay in Packet Tracer.
    Also, if you downloaded the packet tracer activities from Cisco, there's a Frame Relay activity there.
