The Boot Process

An AN/ANH boots using its conﬁgured startup option. The default conﬁguration

for a new AN or ANH is EZ-Install.

(If an initial boot attempt fails, the router attempts to boot once using a different

option. If both boot attempts fail, you must troubleshoot the problem and reboot

the router as described in A

ppendix A.)

The following sections describe the boot process for network and local boot

options.

Network Boot

When booting over the network using EZ-Install, Netboot, or Directed Netboot,

the AN or ANH essentially

1. Powers on.

2. Determines its IP address.

3. Obtains a software kernel ﬁle and/or conﬁguration ﬁle by communicating

with a conﬁgured BOOTP server on the IP network.

4. Reboots, using the newly transferred image.

5. Gets application and string ﬁles over the network as it needs them.

6. Begins bridging and routing network trafﬁc in accordance with the

conﬁguration ﬁle.

The following sections describe in more detail the key steps in this process:

obtaining an IP address and downloading the image and conﬁguration ﬁles.

Getting an IP Address

The AN or ANH gets its IP address from a central-site upstream router.

Note: The upstream router must have a circuit running Bay Networks

Standard Point-to-Point Protocol (PPP) using HDLC or a Frame Relay

permanent virtual circuit (PVC).
