Klaus, you might also try contacting Support and asking about
an e-fix for apar IY12274. This is for the case when the interface
is successfully moved from the router where it is down to the
router where it is up, but the status on the old router is not
recalculated, although the status of the new router is recalculated.
This is for 6.01 systems, I think.

Cordially,

Subject:  [NV-L] Troubles with duplicate ip-adresses





Dear colleagues;

We are at present in the process of applying Tivoli NetView to our
present network surveillance which is running under a static routing
system.

Due to our configuration of a 2 stepped ISDN-Backup, for which 2 routers
each are defined for the same IP-Address the corresponding interfaces
are set to ?down?.

Since these interfaces, under normal circumstances, would be deactivated,
res.,
under backup conditions only one may be active, there can be no IP-Address
conflict when operating normally.

NetView recognizes with every Configuration-Poll, the corresponding
ISDN-Interfaces with the same IP-Address on different routers, which
results
in an  ?Interface xx deleted? for Router A, followed by an ?Interface xx
added?
for Router B.

Our problem is that the ?discovered? Interfaces, which after being
recognized
as having a ?down? status, appear under the corresponding Router in
NetView,
are flagged with an error status of ?marginal?.

For us, at the moment, there isn?t any possibility to identify the
condition of
a
Router in NetView.

We would be grateful if there were anyone who could help to solve our
problem.

A WorkAround which would prevent the new ?discovery? of this Interface,
res.,
that
the Interfaces  ?discovered? are recognized as unmanaged, would be
certainly of
great
service to us.

Thanking you in advance,

Klaus Wich
