Connectivity over Frame Relay Switch

Hey Guys:

How are you? I hope you are doin fine&

Hey, I was just setting up a lab at home& I was creating the Frame Relay Switch config, and it seems to me everythings OK, but I cant ping from R1-R2

Heres the config:

FRS:
interface Serial1/4
description Link to R1
no ip address
encapsulation frame-relay
no ip mroute-cache
logging event dlci-status-change
clock rate 115200
no dce-terminal-timing-enable
no fair-queue
no frame-relay inverse-arp
frame-relay intf-type dce
frame-relay route 312 interface Serial1/5 321
end

interface Serial1/5
description Link to R2
no ip address
encapsulation frame-relay
no ip mroute-cache
logging event dlci-status-change
clock rate 115200
no dce-terminal-timing-enable
no fair-queue
no frame-relay inverse-arp
frame-relay intf-type dce
frame-relay route 321 interface Serial1/4 312
end


R1:
interface Serial0/0/0
ip address 172.12.123.1 255.255.255.0
encapsulation frame-relay
cdp enable
frame-relay map ip 172.12.123.2 312 broadcast
frame-relay interface-dlci 312
no frame-relay inverse-arp
frame-relay lmi-type cisco
end


R2:
interface Serial0/0/0
ip address 172.12.123.2 255.255.255.0
encapsulation frame-relay
cdp enable
frame-relay map ip 172.12.123.1 312 broadcast
frame-relay map ip 172.12.123.3 321 broadcast
frame-relay interface-dlci 321
no frame-relay inverse-arp
end


I already checked the sh frame route at the FRS and the circuits are active, I even activated CDP in all the equipment and actually R1 sees R2 as a neighbor and R2 sees R1 as a neighbor&

I noticed that R1 is not able to ping its own interface even though the physical interface and line protocol are BOTH up, the same with R2.

What do you think is preventing me from ping from R1 to R2?

I guess it should be a layer-3 problem as CDP is a L2 protocol and its working fine, the same with FR as the PVCs are ACTIVE.
