Your server
All other servers or PCs equipped with TCP/IP that you know about
LANs that directly connect your server to other hosts - servers, PCs, foreign hosts, and foreign host gateways
Servers acting as gateways and foreign host gateways on each LAN, and how they are connected to the rest of the network
The IP networks and subnetworks in which your server resides
As many destinations outside your network as possible

Knowing the Configuration Tasks

Specify information that IP interfaces require. You also control interfaces and manage address resolution over LANs. (For planning guidelines, see Chapter 4; for instructions, see Chapter 8.)
Specify foreign host gateways through which you can route IP traffic to a TCP/IP network, subnetwork, or host. (For planning guidelines, see Chapter 5; for instructions, see Chapter 9.)
Integrate the routing functions of VINES and TCP/IP, which work together to route data between servers. This task involves specifying other servers equipped with the TCP/IP Routing option. (For planning guidelines, see Chapter 5; for instructions, see Chapter 10.)
Specify other VINES servers with which you wish to establish a connection through a foreign host gateway. This connection allows workstations connected to your server to access VINES services across the TCP/IP foreign host gateway. (For planning guidelines, see Chapter 6; for instructions, see Chapter 11.)

The IP addresses you specify for other servers in your server's VINES network. The program uses these addresses to establish routes to networks.
IP addresses you assign to interfaces on your server. The program can define routes to networks whose numbers appear in the IP addresses you assign to interfaces on your server.
