The default option. The AN/ANH 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.
