Your IP addressing is wrong. All the frame-relay interface need to be on the same network.

Try this:

Router 2
int s1/0
 ip address 200.1.1.2 255.255.255.0

Router 3
int s1/0
 ip address 200.1.1.3 255.255.255.0

Ip addressing needs to be the same subnet and there is missing DLCI info in your config. Your provider should give you the DLCI info for each site and the ip subnetting is up to you.

>...and there is missing DLCI info in your config

The DLCI does not have to be configured on the router. The router will discover any DLCI's when it receives the full status message from the Frame-Relay switch.

Hi it WORKED when puting the router in the same subnet, i have some questions please:

1. Frame Relay plays like a LAN right ?
2. If it is like LAN, Can I put just Private IP address and Not public ?
3. if I let the configuration as it is, why the routers didn't find other networks using RIPv2?

@donjohnston:what DLCIs that are missing?

Thank you

1)  not really.
2) yes, you can use private addresses.
3) you don't have any networks to advertise.

You're not missing any DLCIs.

@donjohnston:

1) this is what a guy in test out videos said, he said frame relay looks like a private network in some sorts
2) but what about if i there a router in New york and another in Tokyo? how these routers can be attached by the service provider? and maybe private addresses will not work right ? because of distance we will need public addresses?
3) But already i had different networks 200.1.1.0/24 & 200.2.2.0/24 & 200.3.3.0/24 RIPv2 should put them in its routing table no?

1) Well, it is a private network. I just wouldn't say it was like a LAN.
2) Frame-Relay is a layer 2 protocol. IP addresses aren't part of service. Think of it like a really cheap leased line.
3) Routing protocols are used to advertise a network that is behind a router to other routers. If there was a network connected to the ethernet interface of router 1, you could use RIP to advertise that network to router 2 and/or 3. Your previous config was irrelevant since your IP addresses were wrong.

and how the service provider in the USA for exemple can attach a router in newyork and a router in tokyo and another in Russia in a frame relay switch??

Because the provider has frame-relay switches that span the globe or they have interconnects with other frame-relay providers in other countries.

The point is this: Frame-Relay is a layer 2 carrier service that provides point-to-point service between locations. As the customer, all you (need to) know is that your office in New York has a PVC that connects to your office in Tokyo. What you do with that PVC (IP, IPX, Appletalk, IPv6) is entirely up to you. The carrier doesn't know (or care) what layer 3 protocol you're sending over that PVC. And likewise, you have no knowledge of exactly how they're getting your traffic from New York to Tokyo.
