Configuring Dhcp And Bootp Relay; Dhcp; Bootp - Avaya G250 Administration

Configuring DHCP and BOOTP relay

You can configure the router to relay Dynamic Host Configuration Protocol (DHCP) and
BOOTstrap Protocol (BOOTP) client broadcasts to a server on a different segment of the
network. When you configure DHCP and BOOTP relay, you can control how the router relays
DHCP and BOOTP packets. The router also relays replies from the server back to the client.
The G250/G350 can alternatively function as a DHCP server, providing DHCP service to local
devices. For information about configuring DHCP server on the G250/G350, see
DHCP server on page 333. For information about configuring DHCP client on the G250/G350,
see Configuring DHCP client

DHCP

DHCP assigns dynamic IP addresses to devices on a network. With dynamic addressing, a
device can have a different IP address whenever the device connects to the network. In some
systems, the device's IP address can even change while it is still connected. DHCP also
supports a mix of static and dynamic IP addresses.
Dynamic addressing simplifies network administration because the software keeps track of IP
addresses rather than requiring an administrator to manage the task. This means you can add a
new computer to a network without needing to manually assign a unique IP address. Many ISPs
use dynamic IP addressing for dial-up users. However, dynamic addressing may not be
desirable for a network server.

BOOTP

BOOTP is an Internet protocol that allows a diskless workstation to discover the following:
Its own IP address
●
The IP address of a BOOTP server on the network
●
A file to be loaded into memory to boot the workstation
●
BOOTP allows the workstation to boot without requiring a hard disk or diskette drive. It is used
when the user or station location changes frequently. The protocol is defined by RFC 951.
