5-158 Configuring the Internet Protocol

DHCP Relay Functionality

The

 

DHCP

 

Relay

 

functionality

 

is

 

applied

 

with

 

the

 

help

 

of

 

IP

 

broadcast

 

forwarding.

 

A

 

typical

 

situation,

 

as

 

shown

 

in

 

Figure 5

‐

7

,

 

occurs

 

when

 

a

 

Host

 

requests

 

an

 

IP

 

address

 

with

 

no

 

DHCP

 

server

 

located

 

on

 

that

 

segment.

Router

 

1

 

can

 

forward

 

the

 

DHCP

 

request

 

(1)

 

to

 

the

 

server

 

located

 

on

 

N2,

 

if

 

IP

 

forward

‐

protocol

 

is

 

enabled

 

for

 

UDP,

 

and

 

the

 

address

 

of

 

the

 

DHCP

 

server

 

is

 

configured

 

as

 

a

 

helper

 

address

 

on

 

the

 

receiving

 

interface

 

of

 

Router

 

1.

 

The

 

DHCP

 

Relay

 

function

 

will

 

detect

 

the

 

DHCP

 

request

 

and

 

make

 

the

 

necessary

 

changes

 

to

 

the

 

header,

 

replacing

 

the

 

destination

 

address

 

with

 

the

 

address

 

of

 

the

 

server,

 

and

 

the

 

source

 

with

 

its

 

own

 

address,

 

and

 

send

 

it

 

further

 

(2)

 

to

 

the

 

server.

 

When

 

the

 

response

 

(3)

 

comes

 

from

 

the

 

server,

 

the

 

DHCP

 

Relay

 

function

 

sends

 

it

 

to

 

the

 

host

 

(4).

Figure 5-7  DHCP Functionality Example

ip helper-address

This

 

command

 

enables

 

forwarding

 

of

 

local

 

broadcasts

 

specifying

 

the

 

new

 

destination

 

address.

 

It

 

is

 

one

 

of

 

two

 

commands

 

used

 

for

 

UDP

 

broadcast

 

forwarding.

 

Also

 

refer

 

to

 

the

 

ip forward-

protocol 

command

 

which

 

defines

 

the

 

forward

 

protocol

 

and

 

port

 

number.

 

You

 

can

 

add

 

more

 

than

 

one

 

helper

 

address

 

per

 

interface.

 

The

 

command

 

is

 

also

 

used

 

to

 

enable

 

BOOTP

 

Relay.

Syntax

ip helper-address

Syntax of the “no” Form

The

 

no

 

form

 

disables

 

the

 

forwarding

 

of

 

broadcast
