We are currently in the process of implementing DNS for our
NetView environment and have found a problem which we
cannot solve.

Our environment consists of a NetView (5.0) server which feeds
multiple interface-router events to T/EC (3.1), and here's where the
problem manifests itself.  Both servers are running with AIX 4.2.

Our NetView server is also configured as a secondary DNS server, and
whenever NetView resolves the host name to an IP address, it will
always return with a different primary IP address for the router.
It seems that it is selecting the next IP address in an "round-robin"

Because we get a different IP address for each event, T/EC is unable to
correlate clearing events with old down events.  For example, T/EC
will receive a node down event:

      RG100BRA     Node down

when the clearing event arrives, the interface address will be
different, and
hence T/EC thinks it is a different device:

      RG100BRA      Node up

I have included the response to two nslookup commands, the second
executed immediately after the first.  As you can see, for each
command, we get a different IP address as the first interface in the

     > nslookup RG100BRA
     Server:  localhost.bns

     Name:    RG100BRA.corp.bns

     > nslookup RG100BRA
     Server:  localhost.bns

     Name:    RG100BRA.corp.bns

1. We would like to know if there is a way to 'force' NetView to use
   a specific IP address as the primary IP address for the router,
   without having to use the /etc/hosts file?

2. Has anyone implemented DNS, NetView and T/EC successfully?

3. Is there a Redbook which describes this type of implementation?

Any help will be greatly appreciated.
