Yeah!
I already sent a post earlier about that, but there was a grey area if the
requirement required adjacencies over the interface. See earlier post
below.
Hi Steve,
From your post I interpret the question to mean "make sure the EIGRP
process
advertises the 3725 E0 interface (include it in the EIGRP topology), but
this must be done without generating EIGRP packets and must not be
accomplished with passive-interface command)".
I see this requirement being met by redistributing connected and
controlling
redistributed interfaces with a route-map to limit to E0 interface.

Are we talking about a "redistribute connected" maybe with a route-map? ;)
