Hello Guys,
I am attempting configure Frame Relay on my 2 router. I have 2 serial cards only. Evidently I am not doing something right. I need to know if anyone has any documentation on how to configure a point to point using Frame Relay between 2 routers? Thanks. I have tried and can't PING HELP!!!

You should be able to get here few FR scenario configurations.., if no success you may need to post more config info from both routers.

I am not sure from your post whether you are trying to configure routers with a real serial link as Frame Relay or if you are are trying to configure routers back to back as Frame Relay. Since the configuration of a real serial link is easy and examples abound I am assuming that you are trying to do it back to back. It has been a while since I have done that, but my memory is that you need to configure both interfaces as encapsulation frame-relay, you need to configure both interfaces to use the same DLCI, and you need to configure the interfaces with no keepalive (since you do not have anything to generate LMI and LMI is the essential part of keepalives in Frame Relay). Of course you also need to take care of things like clock-rate on the router that will be the physical DCE.

The biggest issue that I see is the
frame-relay lmi-type ansi
under both serial interfaces. Since there is nothing in your back to back connection that will generate LMI, you have told your routers to expect to receive ANSI LMI and when they do not receive it the line protocol stays down. Try removing the frame-relay lmi-type ansi and confiure no keepalive and see what happens.

That did it. Thanks Rick.
