What do you get from a 'show frame map' on r2 and r3, do you just
see a mapping to r1 or are there others? I am not sure that a static
mapping does disable inverse-arp by default, turn it off on all three
interfaces. For r2 to try to establish an adjacency with r3 there must be an
extra mapping somewhere. Maybe inverse-arp got in there before you disabled
it, try a 'clear frame' to force the routers to remap IP to DLCI.
