I need some help in a network design.
Please refer to the attached files, as u can see in the IP file, there are 3 vlans in each cabinet/floor.
The switches in the main DC rack would be either 3750s or 4 Juniper EX4200s using virtual chassis to form a single switch.Top 2 of these chassis swithes serve the different servers as u can see in the scenario diagram and the gateway for these servers would be the SRX Firewall. While the bottom two are for fiber aggregation from cabinets.
Now according to the attached IP/vlans doc, what do u think would be the best place to configure a DHCP server? If I make it on main aggregation switch then I'll have to define 12 DHCP scopes for the differnet vlans rite? then the thin clients gateway would be the aggregate switch and at aggregate switch a default route pointing to the FW would have to be configured?
or should I have to make DHCP server on individual cabinet switches?....
Also, as shown its L2 links between distribution and cabinet switches so how would I fine tune spanning tree for this....What if I make it L3 in order to avoid spanning tree?
Please shed some light on this
