Configuring BOOTP Services
114070 Rev. A 3-5
• If the flag field contains the value 1, the client does not know its own IP
address. The router broadcasts the BOOTREPLY packets to the IP limited
broadcast address (255.255.255.255).
• If the flag field contains the value 0, the client knows its own IP address,
which appears in the client IP address field of the BOOTREPLY packet.
The router sends the BOOTREPLY packet to that IP address and the
link-layer address that appears in the client hardware address field.
Implementation Notes
Bear the following issues in mind when you configure BOOTP services for the
router.
Setting the Router Mode
You must configure the router in forwarding mode for the BOOTP relay agent to
operate. For instructions on configuring the router in forwarding mode, refer to
Configuring IP Services.
Specifying a Forwarding Route for BOOTREQUEST Packets
You must define forwarding routes for BOOTREQUEST packets, using one or
both of the following methods:
• Define a relationship between an input interface and an output interface on the
router (refer to “Specifying Interf
aces to Receive and Relay BOOTP Packets,”
later in this chapter).
• Define a relationship between an input interface and a BOOTP server (refer to
“Specifying Ser
vers for BOOTP Services,” later in this chapter).
Filtering BOOTP and DHCP Packets
The Dynamic Host Configuration Protocol (DHCP) also uses the BOOTP relay
agent to forward packets. Refer to Chapter 4 for further information on DHCP. To
reduce network traffic, you may want to control whether an interface transmits
BOOTP packets, DHCP packets, or both. For example, you may want to set a
filter to prevent BOOTP traffic from traversing a network segment that contains
DHCP servers but not BOOTP servers.
