Sami,
Since all DLCIs get dumped on the physical interface by default, it might
not be of any use configuring 'no frame-relay inverse-arp' on the
subinterface, because there will be no DLCIs on the subinterface to
inverse-arp on, except the ones you manually assign to that subinterface via
'frame-relay interface-dlci <dlci>'.
It is very easy to run into problems when you disable inverse-arp on a
multipoint interface. The frame-relay interface-dlci command relies on
inverse-arp to be able to map the remote end to the locally assigned DLCI
number and as such inverse-arp is enabled by default on all subinterfaces.
One will not be able to disable it on a point-to-point interface, no matter
how hard you try.
If you disable inverse-arp on a multipoint interface, you have to use
'frame-relay map' statements because your 'frame-relay interface-dlci
<dlci>' statements will not work, at least this has been my experience.
Do a simple verification test and see if you will see those '0.0.0.0'
mappings (using show frame-relay map) referencing your subinterface if you
leave inverse-arp on.
