Setting up VLANs and Bridges

[lwslarry]

I have 3 Buildings connected by fiber, 3 Extreme Summit 24e3 layer 3 switches and one Cisco 36xx router. I intend to connect the cisco, which my ISP provides with 3 public IP ranges, to Summit #1 port 24. I also intend to setup a redundant ethernet port 23 to connect to a DSL Modem/router. Summit 1 has two active gbic ports, one each for Summit #2 & #3. I intend to set up 8 VLANs, of which will use public IP addresses, the rest are private. One VLAN will span Summit #1 & 2#, but I wish all VLANs to utilize the ISP connection and future services (E.G. Echange, SQL....)I am planning.

Are there any examples I can see anywhere? I'm looking for proven Ideas IP schemes for multi VLANs.

I realize I need to set up a defalt VLAN, I'm planning a private range which my ISP trunk will abide.

Two VLANs I need to config for 2 separate public IP subnets.
