Example 5: Learning from Other Routers

This example provides an alternative way to configure the router when other AppleTalk routers are present on one or more of its networks. It uses exactly the same network setup as Example 4: EtherTalk 2.0 with Other AppleTalk Routers, but it allows the AppleTalk router to "learn" its network configuration automatically by "listening" to the other AppleTalk router.

The basic network in this example is the same one shown in Figure 18. In this example, the EtherTalk 2.0 network will be configured as a "non-seed interface."

Figure 22
Configuring a Non-Seed Interface

NOTE:  In this example, the EtherTalk 2.0 interface in the server is configured as a "non-seed interface" by assigning the network range "0-0." This instructs the router to obtain its configuration from existing routers on that network.


Example 5 Configuration Data

In this example, you will configure the router using this data:


Table 12. Example 5 Configuration

Configurable Component Example Data

 

Internal AppleTalk network

net=55002 zone={"Admin","Q zone"}

Use a unique network number. See Note below about multiple internal zones.

EtherTalk 2.0

net=0-0

Non-seed interface

NE2000 LAN driver

frame=ETHERNET_SNAP

 

AFP file services

Installed (no options used)

 

ATPS print services

Installed, one print queue for LaserWriter (named "Pubs LW") on the LocalTalk network

 

NOTE:  This example shows how to configure more than one zone on the internal network. The purpose of configuring multiple zones on the internal network is to allow print queues to be advertised in any one of these AppleTalk zones. (AFP file services are always advertised in the first zone entered for the internal network, which is the default zone for the internal network.) To configure multiple internal zones, you must be operating in a Phase 2 environment, where no Phase 1 routers are present.


Example 5 Configuration Procedure

To enter a configuration that will be in effect when you bring up the server, follow the steps in this section.

  1. Load INSTALL, select Product Options in the main INSTALL menu, and then press <Enter> on the line specifying NW-MAC v3.12.

    If you have just finished installing the NetWare for Macintosh software and are running INSTALL, skip this first step.

    When you press <Enter>, the Editable Configuration Files menu opens.


  2. Highlight STARTUP.NCF and press <Enter>.

    Add these to the existing commands in STARTUP.NCF:

    load mac

    set minimum packet receive buffers=100

    See The Macintosh Name Space and AppleTalk Stack/Router Memory Requirements if you would like an explanation of these commands.

    Press <Esc> and then <Enter> to save changes to STARTUP.NCF.

  3. Use the arrow keys to highlight AUTOEXEC.NCF and then press <Enter>.

    Add the NetWare for Macintosh configuration commands to the existing commands in AUTOEXEC.NCF. The commands required for this example configuration appear in bold monospace type in Figure 23.

    Figure 23
    Example 5 AUTOEXEC.NCF

    NOTE:  Before loading the AFP or ATPS modules, you must load the AppleTalk module and bind AppleTalk to one or more LAN drivers, as shown below.

  4. Load the AppleTalk module and configure the internal network:

    load appletlk net=55002 zone={"Admin","Q zone"}

    If you would like more information about this command line, see Loading the AppleTalk Module.

  5. Load the LAN driver and AppleTalk frame type:

    load ne2000 int=2 port=300 frame=ethernet_snap name=esnap

    The NAME option is a NetWare driver-naming feature that lets you specify a name for a specific configuration. This option is described in the NetWare v3.11 System Administration manual. For more information, see Loading LAN Drivers with AppleTalk Frame Types.

  6. Bind AppleTalk to the LAN drivers and configure the AppleTalk networks:

    bind appletlk esnap net=0-0

    The name esnap is specified in Step 5 and refers to the driver name assigned in the LOAD command.

    The parameter net=0-0 creates a non-seed interface. The router will listen for information from other routers on that network for its own configuration data.

  7. Load the file and print service modules:

    load afpload atps

    For details on the AFP configuration options you can specify on the LOAD command line, see Setting Up a Specialized Environment.

    Press <Esc> and then <Enter> to save your changes and to return to the "Editable Configuration Files" menu.

  8. If you are ready to enter a print queue configuration, highlight ATPS.CFG in the menu and then press <Enter>.

    See Step 8 for instructions on creating a print queue for the LaserWriter shown in this example.

  9. Exit INSTALL, saving your changes.

You can now complete the configuration procedure by downing the server or by re-entering the STARTUP.NCF and AUTOEXEC.NCF commands at the server console. Please see Step 10 for instructions.
