The Network Boot Process

This section describes the boot process for the network boot options. For

information on the Local Boot procedure, see Quick-Starting Routers and BNX

Platforms.

The following occurs when the ASN boots over the network via EZ-Install,

Netboot, or Directed Netboot:

1. The ASN boots a software image that resides on a local ﬁle system ﬂash card

(asn.exe).

2. The local software image conﬁgures the ASN’s network interfaces to use IP.

3. The router determines its IP address.

4. The router obtains a software image ﬁle and/or conﬁguration ﬁle by

communicating with a conﬁgured BOOTP server on the IP network.

5. The router reboots, using the newly transferred image.

6. The router begins bridging and routing network trafﬁc in accordance with the

conﬁguration ﬁle.

The following sections describe key steps in the process — obtaining an IP

address and downloading the image and conﬁguration ﬁles — in greater detail.

Getting an IP Address

The ASN gets its IP address from a central-point upstream router.

Obtaining the IP Address Manually (Netboot and Directed Netboot)

For Netboot and Directed Netboot, you conﬁgure the ASN’s IP address manually.

Chapter 3 describes how to use Site Manager to conﬁgure Netboot interfaces.

Chapter 4 describes how to conﬁgure the IP address using the Technician

Interface.

Note: The upstream router has either a circuit running Bay Networks

Standard protocol or a Frame Relay permanent virtual circuit (PVC) in direct

or group access mode.
