Hi all,
I have an unrecognizing problem.
Mi environment is Framework 3.6 and Netview 5.1.1 on AIX 4.3.0.0.

Some nodes, or segments, aren't connect to the ipmap.

The two problems are like those:

gw.diei.unipg.it      141.250.40.30    gw.diei.unipg.it      141.250.40.30
ERROR finding route from cipg01.unipg.it to gw.dimisem.med.unipg.it:
Route bound to an interface which is realized via a broadcast media.
This may be because node cipg01.unipg.it is running proxy ARP (also known
as ARP hack or promiscuous ARP).  Change the starting node to a gateway
in the same network as cipg01.unipg.it which is not running proxy ARP
and try again.

P.S.  ------Minosse.unipg.it -> NetView Server
        ------Destination Node -> It is in the map but separate.

This events are present only in the Netview Environment (SNMP); I haven't
problems with normal operation
or test like traceroute.

Thanks in advance,
