Obtaining the IP Address Manually (Netboot and Directed Netboot)
For Netboot and Directed Netboot, you configure the IP address manually.
Cha
pter 4 describes how to use Site Manager to configure Netboot interfaces.
Cha
pter 5 describes how to configure the netboot interfaces using the Technician
Interface.
Obtaining the IP Address Automatically (EZ-Install)
During the EZ-Install process, the router obtains its address automatically, as
described below.
1. When you power on the AN/ANH, it runs a set of diagnostic tests.
2. The AN/ANH sends a BOOTP request to the upstream router for an IP
address and subnet mask.
The AN/ANH issues the request through all synchronous ports at about the
same time, even if cables are not connected to these ports. Each port
successively tries the following protocols until it receives a response:
• Bay Networks Standard PPP using HDLC (high-level datalink control)
encapsulation
• Frame Relay Annex D
• Frame Relay Local Management Interface (LMI)
• Frame Relay Annex A
The AN/ANH makes two attempts for each protocol. If it does not receive a
response in approximately 4 minutes, the AN/ANH boots the default image
and configuration file in its local file system, as described in the next section,
“Local Boot
.”
3. The first interface on the upstream router to receive the BOOTP request
responds.
4. The upstream router calculates the IP address of the AN/ANH’s synchronous
interface.
How the upstream router calculates the IP address depends on its protocol
configuration. See Step a if the upstream router circuit is running Bay
Networks Standard or is a Frame Relay permanent virtual circuit (PVC) in
direct access mode. See Step b if it is a Frame Relay PVC in group access
mode.
