Need Help Configuring My Network for VLANs across multiple Layer 2 Switches (Visio PDF Provided)
Posted on 2006-06-05
I need some assistance developing my plan to deploy Sonicpoints across my network of managed switches as well as a DMZ for my mail server. I am not a networking guru, but I do know enough to potentially avoid needing explanations of elementary networking concepts. My main weakness is when it comes to routing, so be very clear when discussing that.
First, about my Sonicwall: If you're not familiar with a Sonicwall 3060, it has five physical interfaces (X1 - X5) that can be configured for zones such as LAN/WAN/WLAN/DMZ.
Currently, my switches are all Dell PowerConnect (all VLAN capable) but are all configured as one default VLAN. So basically, they aren't being used for VLAN.
What I need is to be able to configure VLAN 1 for internal LAN. VLAN 2 for DMZ. And VLAN 3 for WLAN. Eventually a VLAN 4 for a VOIP system. What is MOST IMPORTANT due to the geographic size of my network is that I need the VLANs to traverse my managed switches. I believe this is called "VLAN trunking" but I am not sure.
I believe to accomplish this i need Layer 3 routing between the switches. Currently, as you can see from my Visio PDF diagram, there is NO routing equipment anywhere on the LAN (Sonicwall does not count.) So it is a given I will need to buy some.
The questions are:
1. Is there a better scheme that I haven't considered?
2a. What type of routers/ layer 3 switches do I need to make this plan happen?
2b. What models do you recommend?
3. How many do I need?
4. Where SPECIFICALLY should they be deployed on the diagram?
5. What are the negative side effects of deploying the recommended equipment (speed loss, etc?)
I would *LIKE* to minimize the amount of new equipment necessary, maintain the ability to go 1Gbps on my fiber runs if possible, all the while maximizing the ability of the VLANs to traverse my network. But please do not rule out 100mbps routers if they are very cheap.
