I am using a private address for the LAN. 10.10.3.0/24 . All our 2003 servers Exchange/DC/DHCP/File Server and 50 XP clients are on the same network. I am using 4 Catalyst 2550 10/100 Switch. The network has 50 Cat 5 Cable Jacks and 10 Cat 5e Cable Jacks. I want to improve the network access for the users, by bringing in a Gigabit Layer 3 Switch for servers.
I want to create department VLANs and establish routing between the VLANs for users to have access to the servers.
I want to create following department VLANs for XP users all on old Cat 5 Cable 100 MB
Sales VLAN- Network ID: 10.10.50.0/24 (20 Users Currently)
Logistics VLAN - Network ID: 10.10.51.0/24 (10 Users Currently)
Finance VLAN - Network ID: 10.10.52.0/24 (10 Users Currently)
OfficeAdmin VLAN - Network ID: 10.10.53.0/24 (5 Users Currently)
IT VLAN - Network ID: 10.10.54.0/24 (5 Users Currently)
Server VLANs all on Cat 5e cables (1000 MB)
DC- VLAN - Network ID : 10.10.3.0/24 (Domain Controller/DHCP/DNS) Static IP
Exchange-VLAN- Network ID: 10.10.4.0/24 (Exchange Server) Static IP
File Server-VLAN- Network ID:10.10.5.0/24 (File Server) Static IP
The DHCP/DNS/DC is on network 10.10.3.0/24 ,
What is the best recommended way for all the XP users in different department VLANs to receive respective VLAN IP addresses from Server 2003 DHCP and access to the server resources on different VLANs?
Should I use Ip helper address for each vlan interface to get to the 2003 DHCP server or create a Local DHCP Scope for each department VLAN on the Gigabit Layer 3 Cisco Switch and disable Server 2003 DHCP?
Objective: Reduce Network boradcast from XP Clients by using VLANs and get better performance from the servers by moving them to Gigabit ethernet each on seperate VLAN.
Please advise the best practise.
Thanks in advance.
