Re: quick question?

I think, you can use virtual address (especially in Cisco, ip address ...
secondary) for
new network.
For example, router has as local network's ethernet port.
If you want to use new address block at same network,
you can assign to same port's secondary.
It's syntax is simple.
If your cisco router port is e0, you can use this serial command as reference.

router> ena
Password:        <-- enter enable password
router# config
inter e0
ip address secondary
router# wr

It is simple. If the customer's network has one backbone, this method can
handle their network as seperate two network. ;>
And every computer set their subnet's router IP address for their gateway
Is it clear?
If you have problem with this, please e-mail me. ;>
