Configuring BOOTP Services

2-7

• Action: DROP

The user-deﬁned ﬁeld has the following attributes:

• Reference: after IP header

• Offset: 224 bits (7 longwords into the BOOTP header)

• Length: depends on the media (48 bits for LANs)

Using Unnumbered Interfaces

You can conﬁgure BOOTP services only on a numbered network interface. For

instructions on numbering a network interface, refer to the book Conﬁguring

Routers or Conﬁguring Customer Access and Trunks (BNX Software), depending

on the type of installed software.

Although you cannot conﬁgure an unnumbered interface to accept BOOTP

requests, you can conﬁgure the router to transmit BOOTP requests from an

unnumbered interface. To relay BOOTP packets through an unnumbered

interface, you must specify an input interface on the router and a server in the

BOOT Relay Agent Preferred Server Table window (refer to Figure 2-9). The

router can then unicast a BOOTREQUEST packet through normal IP services to

that server. For instructions about this procedure, refer to “Specifying Servers for

BOOTP Services,” later in this chapter.

Enabling BOOTP Services

This section describes how to enable IP and BOOTP services simultaneously. If

you want to add BOOTP to a circuit on which you have already conﬁgured IP,

refer to Conﬁguring Routers or Conﬁguring Customer Access and Trunks (BNX

Software), depending on the type of installed software, for information on adding

a protocol.

When you enable BOOTP services, you are required to conﬁgure only a few

parameters. The Conﬁguration Manager supplies default values for the remaining

parameters.

This section assumes that you have read Conﬁguring Routers or Conﬁguring

Customer Access and Trunks (BNX Software), depending on the type of installed

software, and that you have

1. Opened a conﬁguration ﬁle

2. Speciﬁed router hardware if this is a local mode conﬁguration ﬁle
