I am starting down the path to subnet my network using Vlans and I am new to this setup. Here is our current config.
We have a 6509e core. We have a VTP domain setup on the core. We have a 16 closets that are connected back to the core via fiber. Everything currently is setup on Vlan1 with a class B 128.1.x.x ip address. I have the switches connected to the core using 802.1q trunk.
I went out to one my switches (3560) and created a new Vlan, assigned my new IP address (192.168.204.0/24). After doing this I can see the Vlan on the core.
Couple of questions,
Do I need to IP address the two interfaces that connect the core to the 3560 switch with a /30 ip address so I can route to the new ip address or what do I need to put into place to be able to make this happen?
The other question is as we are moving over to the new ip addresses there is a lot of manual config that has to be done, mainly address and setup printers. Can I create another Vlan (that will be deleted later) so the 128.1 network will continue to function so I can have more time to move the printers?
