Jlsplit addressing" with Option 9

In the example configuration shown in Figure 3-9, the gateway is configured on the Ethernet/IP subnet 130.57.64. The client Macintosh IP addresses will be allocated as a range that is noncontiguous with the gateway's IP address. Option 9 must be ON.

LocalTalk network supporting 9 Madntoshes running TCP lIP software. The IP adares ... ~

for these Macs will begin at at a separate (noncontiguous) address on the same IP network.

IP data:

Option 9:

IP Address of FastPath Box:

local Parameter #1 : (Clients) Dynamic:

(Clients) Static:

Ethemet/IP network: 130.57.64.0, subnet mask 255.255.255.0 (FFFFFFOO).

Figure 3-9. Using a noncontiguous range of client addresses Note that the client addresses begin with the Local Parameter #1 address, not the Local Parameter address + 1. The following IP addresses will be available for static assignment to client Macintoshes:

130.57.64.50 130.57.64.51 130.57.64.52 130.57.64.53

The following IP addresses will be available for client

Macintoshes to acquire dynamically as they boot up on the IP network:

130.57.64.54 130.57.64.55 130.57.64.56 130.57.64.57 130.57.64.58

1111'" This entire range of addresses cannot be duplicated anywhere

on the IP internet.

In configuring the gateway, you should follow the general procedure described in Chapter 1. After connecting the gateway to a Macintosh via LocalTalk, launch the FastPath Manager, and select and open the gateway. In the main configuration dialog box,

• Click the Reset button, then open the gateway again.

• Click the Pause button.

• Enter the AppleTalk configuration data; see Chapter 2 •

• , Turn on Option 9 in the Options window.

• Select K-STAR IP from the Configuration menu and double-click on the K-STAR IP listing in the

Configuration area.

• Enter the IP address of the FastPath Box.

• Click More.

• In the Local Parameters field #1, type the IP address that will be the starting point of the client IP address range.

• Enter the number of client Macintoshes controlled by the gateway.

• Turn on the Remote Boot switch (optional).

• Download K-STAR.

• Click the Go button.

• Save the configuration data in a file (optional).

This example uses the internet configuration shown in Figure 3-9.

For your site, you should determine the proper IP addresses for the gateway before you configure it.

Option 9:

IP Address of FastPath Box:

Local Parameter #1 : (Clients) Dynamic:

After selecting Reset and then Pause, enter the AppleTalk configuration you require, as described in Chapter 2. Then proceed with the IP configuration:

1. Click the Options ... button in the main configuration dialog box. This brings up the Options window.

2. Turn on Option flag 9 by clicking in the selection box next to the number 9 (an X appears in the selection box when the option flag has been turned on), then click OK to close the Options window.

This message indicates that the gateway has come up on the internet with Option 9 set, so the split addressing feature is in effect. No IP error messages are showing in this window, so you can check the configuration as described in Chapter 1. See Appendix C for a description of IP error messages that could appear here.
