Inverse ARP is enabled by default for all DLCI's. It's not particular to an
interface type or not.
What he's getting at is two-fold.
1. If you have a sub-interface, you must ASSIGN a DLCI here, nothing gets
stuck their automagically.
2. If you have a static mapping, this overrides a dynamic one when you look
at the "show frame map" output.
Normally we look at having inverse arp off because the exam tells us to. If
we have a full mesh of PVC's, we'd learn about connections that we should
have via our physical interface (leftover/unassigned dlci's).

Brian,
If it's not too much bother (I'm sure you know them off the top of your
head), can you tell me for which (sub)interface types inverse-arp is
en/disabled?
Thanks!
Ken

The rule of thumb is that the command is applied wherever
the IP
address is assigned.
As a side note, if using multipoint subinterfaces with only
static
mappings then InARP does not need to be disabled.

Can the command "No Frame-relay Inverse-Arp" be applied on a
sub-interface
or has to be a physical interface.
If there is a case where Hub router has a multipoint interface to
spoke 1
and
spoke 2, and another multipoint interface to spoke 3. The scenerio
requires
that dynamic frame-relay must be disabled on first multipoint
interface, and
not on second one.
