Two Networks

[Guest]

I have been delegated the task of creating an additional network to run
parallel to our existing network. Our existing network is 10/100 and the IP
mask 192.168.1.0. The second network is going to be 100/1000 and the Scheme
should be dissimilar to our existing one. Our goal is to add Gb cards to our
servers and use the second network as a backbone for our Backup Strategy.

I have an idea on how to pursue this but wanted to verify with those of you
that have accomplished this so I could avoid any issues.
I plan to make the Second network mask 192.168.0.0. Then not configure any
gateways with these cards. I want to avoid any DNS registrations for these
cards and only want traffic generated from Veritas to travel over this
network.

Any suggestions would be extremely helpful.

I think you're on the right track, Tony. One suggestion would be to put more
separation between networks. 192.168.0.0 can be combined with 192.168.1.0
with a mask of 255.255.254.0 to increase your network hosts without having
to re-ip or add routers in the future. If you put the "backup" network on,
say, 192.168.129.0, that would leave you a world of room for easy expansion
on both sides.

Thanks for your help here. So your suggesting I change the Subnet mask on
all workstations and servers to .254 or just the second network with the IP
mask of 192.168.129.0?
At one point I was good with TCP/IP but it is obvious, I have been out of
practice.

Not suggesting anything other than it would leave the option open should the
need arise.

I read from your first post that you were setting up two physical networks,
but in the other threads I'm seeing that this is not the case. There is lots
of good advice in the other thread.

Thanks Kurt. I am taking everything into consideration here and want to
provide myself a long term solution as well as one that works today.
