I have 2 routers connected through the Frame Relay switch. On the first router (R1) I'd like to use static DLCI-IP mapping, but on the second (R2) I'd like to use Inverse ARP. Inverse ARP doesn't work. Output of 'show frame-relay map' is empty.
inverse ARP works based on the fact the the remote DTE (R1 in your case) cooperates by sending frames that travel on the PVC telling "Hi at the other side of this PVC there is my interface and my address is x.x.x.x".
Now, you have only two DTE on a point-to-point PVC. On R1 you have configured the interface with:
frame-relay map ip 126.96.36.199 132 no frame-relay inverse-arp
the second command does not tell R1 to ignore inverse ARP messages coming from R2 but tells R1 to suppress its own messages.
As a result of this R2 is waiting for inverse ARP messages that will never come.
To be noted the FR switch has no role in this: its job ends when it switches FR frames from one port to the other port it does not take part in inverse ARP process.
So if you want to build a working example of inverse ARP you need to have it enabled on both DTE at the two ends of the PVC or move the frame-relay map command on R2 side
