Basic Network Design

The main function of the manufacturing zone is to isolate critical services and applications that are important for the proper functioning of the production floor control systems from the enterprise network. This separation is usually achieved by a Demilitarized Zone (DMZ). The focus of this paper is only on the manufacturing zone. This chapter provides some guidelines and best practices for IP addressing, and the selection of routing protocols based on the manufacturing zone topology and server farm access layer design. When designing the manufacturing zone network, Cisco recommends that future growth within the manufacturing zone should be taken into consideration for IP address allocation, dynamic routing, and building server farms.
