And that could very well be. It's not like Cisco has ever been told their
programmers are always consistent. :)

Looks like this may be another case of "depends on the IOS version".
"...If you change from a point-to-point subinterface to a multipoint
subinterface, then change the subinterface number. Frame Relay Inverse ARP
will be on by default, and no further action is required..."

My point was that if inverse arp is enabled on a subinterface, disabling
inverse arp on the physical interface won't automatically disable the
inverse arp for the subinterface. The original question was asking if you
could just disable on the physical interface and affect all subinterfaces at
the same time.

Actually, inverse-arp is automatically turned off on subinterfaces. The
only caveat is that it will RESPOND to an inverse arp if one is received,
but otherwise will not generate its own...

It needs to be disabled wherever you have IP addresses. If you just have
addressing on the physical interface, it just needs to be disabled on the
physical interface. If you have addressing just on subinterfaces, it needs
to be disabled on the subinterfaces. If you have addressing on both the
physical interface and subinterfaces, it needs to be disabled on both.

Importance: Low
Quick question on frame relay and inverse-arp...
If you're asked not to rely on dynamic resolution, and you are using p2p or
p2m subinterfaces, can you disable it on the physical interface alone or do
you need to disable it on both the physical and subinterfaces? Can't check
it out at the moment myself ....
Thanks
Roy
