IP and IPX Install Option

These systems have the TCP/IP and IPX stacks loaded. Systems installed with both IP and IPX are configured to establish NCP connections either over the TCP/IP stack or over the IPX stack. Figure 7 shows the relationship between the protocol stacks when installing a system with IP and IPX.

NetWare servers installed with IP and IPX have the following capabilities:

• They can establish NCP connections with pre-NetWare 6 clients or with NetWare 6 clients without regard for the option used to install it.
• They can execute IPX applications and communicate directly with other IPX nodes.
• They can execute IPX applications and communicate through a Migration Agent with NetWare 6 systems installed with IP alone.

NetWare clients installed with IP and IPX have the following capabilities:

• They can establish NCP connections with pre-NetWare 6 servers or with NetWare 6 servers installed with one of the install options that include IPX.
• They can establish NCP connections with NetWare 6 servers installed with IP if the clients are able to obtain IP addresses for those servers.
• They can establish NCP connections through a Migration Agent with NetWare 6 servers installed with IP if the clients are only able to obtain IPX addresses for those servers.
• They can execute IPX applications and communicate directly with other IPX nodes.
• They can execute IPX applications and communicate through a Migration Agent with NetWare 6 systems installed with IP.

Having a NetWare client installed with IP and IPX does not guarantee that the client will be able to establish an NCP connection with a server installed with IP without the use of a Migration Agent. The type of address obtained by the client when trying to connect to a server determines the protocol stack utilized to establish the connection. Applications that obtain address information from the bindery will not be able to connect with servers installed with IP if there is no Migration Agent installed, and if the client is installed with IP and IPX. Notice that this problem does not exist if the client and the server are installed with IP alone.
