TCP/IP Routing

TCP/IP Direct Connect is a Network Driver Interface Specification (NDIS) compliant adapter driver. TCP/IP Direct Connect makes the PCI ESCON Adapter appear exactly like any other Network Interface Card (NIC) to the Windows server. As a result when TCP/IP Direct Connect and a PCI ESCON Adapter are installed along with one or more Local Area Network (LAN) adapters the Windows server becomes a multihomed system.

Microsoft’s Windows 2000 and NT TCP/IP protocol stack is capable of performing static IP routing in multihomed servers. Static IP routing may be used to route TCP/IP traffic across the PCI ESCON Adapter to the IBM mainframe. This chapter discusses how to configure both your network and Windows server to take advantage of this capability.

Figure 5-24. Network with 2 Subnets

Figure 5-24 shows a simple network made up of two sub-networks connected by a router. A single Windows server is installed on the Token Ring. Windows 95 and /or 98 is installed in all workstations. An IP subnet mask of 255.255.255.192 is being used to allow for four subnets with IP addresses as follows:
