When using Frame-Relay, how to use it without using a subinterface?

[Translator]

Hi, all. Please help me on this.

I need OSPF routing in the following environment and I want to use Frame-Relay without using subinterfaces.

Hello
Usually to use FR  you need to map data link connection ids (DLCI) via a FR switch, in your post it looks like you are using packet tracer which has limited features for simulation and assuming won’t support this anyway, however  is seems you have direct back-back serial connections so in this case you need set the clocking on the serial interfaces so one side of the connection is a DCE and the other is DTE  with he same DLCI mapping;

Example:

rtr1
int serial x/x
ip address 1.1.1.1 255.255.255.252
encapsulation frame-relay
no keepalive
clock rate 64000
frame-relay map ip 1.1.1.2 102

rtr2
int serial x/x
ip address 1.1.1.2 255.255.255.252
encapsulation frame-relay
no keepalive
frame-relay map ip 1.1.1.1 102

I agree with @paul driver on how to do FR without sub-interfaces, but why do you want to do that? I consider the use of sub-interfaces to be the preferred way to use FR unless there is some other constraint.
