Make sure you disable frame-relay inverse arp on all the router serial
interfaces. Remember, disabling it on the interface stops that interface on
the local router from sending inverse arps out, but not from answering them
from other routers. If another router inverse arps the local router, the
local router will still install dynamic maps even though you have it turned
off.
