How does inARP actually work? It doesn't send a broadcast packet out so how does inARP actually work? I realize that the router knows which DLCI and the goal is to learn the IP addresses associated with that DLCI.
I have a specific example.
Volume 1 Frame-Relay lab 2.9.
Router 5 is setup with multipoint sub-interface connecting to R1 and R2.
router 1 and router 2 both are using physical interfaces. You are also instructed to disable inverse-arp per dlci which I have done and obviously at that point router 1 and router 2 are not able to talk.
When I remove the inverse arp on let's say r1, then inverse-arp does its thing and router 1 can now talk to r2. Now this is going through R5 so how does inverse arp work going through R5s multipoint interface?
