Hi,
So you mean that "no frame inverse-arp" disable both the send out of the inarp request and responds to inarp?
I also try it in lab also, however, I found out that "no frame inverse-arp" does not disable the reply to inarp. That mean if R1 disable frame inarp, it would not send out inarp and we have to enter static map. However, R2 still will get the dynamic map.
Therefore, I think there should be a command to disable the reply to inarp request. In "CCIE Practical Study Vol 1", it said the command "no arp frame-relay" has this purpose, but I tried in lab and it doesn't works.
