Company has 11 departments, respectively is: general manager, finance, operations, purchasing department, design department, ministry of personnel, resources and development department, logistics department, warehousing department, quality department, information department, the server group, now the company wants to general manager, the finance department, personnel department, purchasing department into a subnet, resources, development department, quality department into a subnet, logistics, warehousing department into a subnet, operations a single subnet, ministry of information and the server group into a subnet (terminal number around 550),
Under the existing several problems need to consult you bosses:
1. The ministry of information and the server group subnet hope into general area, is all subnets can be in the company with the subnet visits,
2. It is divided into several classes should be used to address more appropriate, if you use a class B IP address whether equipment performance requirements of a router?
3. Whether such division of the network need to use layer 3 switches?

Thank you,

The purpose of the division of Vlan, is to prevent the network storm, also for the convenience of management, since is each other, why want to row so big of subnet? Subnet should draw a little bit small, front said, to prevent the network storm, really need to use layer 3 switches,

Thanks for the reply of, because the server group is a domain control server, the file server, so need each other

No such thing as A or B class, the use of class A can you subnet, you can use the 24 mask, you subnet of router performance requirements, basic can be implemented, the key is to access traffic volume is not large, routing will produce bottleneck, also can through the key strategy to ensure normal traffic flow, according to the demand of equipment type selection,
Some 2 switching also support the vlan, but features missing, core or use multilayer exchange,
Communication between different vlans, needs to have the routing, the other all vlan and server group's vlan access configuration routing
