Selecting a Boot Configuration
1-13
Netboot
You can use Netboot if
• The ASN has a communications link to an upstream router over an Ethernet,
HDLC, or Frame Relay interface.
• The ASN has a local console or modem connection.
• A directory on a BOOTP server contains an ASN software image file and a
customized configuration file.
• You provide a network configuration file customized for the ASN.
• You configure an IP address for the ASN’s boot interface.
Netboot takes longer than EZ-Install, but minimizes the cost of line usage and
prevents saturation of the router’s memory.
Local Boot
When you use Local Boot as the initial boot option, the router boots a default
(generic) configuration file. You must then complete the “Quick-Start” installation
script to customize the default configuration file and save it locally. Refer to the
manual Quick-Starting Routers and BNX Platforms.
Recommendations
Even if you choose EZ-Install, we strongly recommend that you connect a modem
or a console to the router. With a console connection, you can issue commands to
the router and display messages. This is very useful if you have network problems
after installing the router.
