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"
fashion.
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 10.0.7.131 Node down
when the clearing event arrives, the interface address will be
different, and
hence T/EC thinks it is a different device:
RG100BRA 10.22.0.2 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
router.
> nslookup RG100BRA
Server: localhost.bns
Address: 127.0.0.1
Name: RG100BRA.corp.bns
Addresses: 10.0.7.131, 10.22.0.2, 10.22.0.6, 10.170.0.1
10.171.0.1, 10.0.12.3, 10.0.4.189
> nslookup RG100BRA
Server: localhost.bns
Address: 127.0.0.1
Name: RG100BRA.corp.bns
Addresses: 10.22.0.2, 10.22.0.6, 10.170.0.1, 10.171.0.1
10.0.12.3, 10.0.4.189, 10.0.7.131
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.
