<br>
As Richard suggests, I suspect the config you proposed is going to cause Xymon,
and yourself a world of hurt.<br>
Remember, Xymon uses the hostname as the index (for lack of a better word)<br>
Now you have the same host with 2 IP addresses.<br>
Xymon will perform 2 pings, using lookup to resolve IP. bbtest-net is going to
bleat.<br>
I suspect, the IP address from the lookup is the one that will be used as the
DNS server IP.<br>
So both DNS lookups will be to the same IP address.<br>
<br>
I would suggest a simple script to do what you need.<br>
