To
initially
start up the ASN, you can use one of these options:
• EZ-Install (the default)
• Netboot
• Local Boot
To start up the ASN
after
the initial configuration, you use one of these boot
configuration options:

Table 1-1 summarizes the startup options. The section that follows, “The Network
Boot Process,” describes what happens when you use each option.

EZ-Install
Local
(Flash

Network
(Synchronous
connection)
The default option. The ASN boots from a software image in
local memory, then transmits a request for its IP address
and configuration file through an attached synchronous
interface.
Next, a remote UNIX- or DOS-based workstation that is
configured as a Boot Protocol (BOOTP) server downloads a
customized configuration file; you save that configuration to
Flash memory.
Requires a communications link over an HDLC or Frame
Relay interface.
If EZ-Install fails, the router tries the Local Boot procedure.
