Frame Relay Packet tracer Lab

I have been trying to complete the frame relay packet tracer lab from packet tracer network. When I go to add a subinterface I am getting an error of "%cannot create subinterface" Is there a prerequisite for creating a subinterface, or is it blocked in the lab?

Don't have the hardware to do frame relay, and no GNS3 experience. So if anyone has any other labs they would recommend for frame-relay it would be appreciated.

    Set encapsulation to frame-relay on the physical interface, then try to create the sub.

    Yeah, in order to create a sub interface on a serial interface you have to first set the encapsulation to frame relay.

    Ok, figured it out.

    int s0/0/0 point-to-point
    int s0/0/0.100 point-to-point

    I was not using the ? while entering commands. I had the encapsulation of the interface set to frame-relay, but was not defining the type of connection it was supposed to be.

    Thanks for your help.

    That was the problem I was having too. Thanks for posting your findings out here!

    Youtube has a some videos dealing with Frame Relay & Packet Tracer.
