Setting Up the Routing Path from the DHCP Server

to the Router

You must define a routing path between the DHCP server and the router

configured as a BootP relay agent to ensure the transmission of packets from one

end of the network to the other. You define this routing path by:

• Specifying interfaces to receive and forward DHCP packets

• Defining a DHCP server

Specifying Interfaces to Receive and Forward DHCP Packets

BootP/DHCP relay uses the BootP relay agent to forward packets to and receive

packets from DHCP servers. You must define a forwarding route for DHCP

packets by defining a relationship between an interface that receives DHCP

packets from clients and an interface that sends DHCP packets to servers.

When you define this type of relationship, the interface pair appears in the BootP

relay agent forwarding table. For instructions, see “Specifying Interfaces to

Receive and Relay BOOTREQUEST Packets” on page 4-14.

Using the BCC

To allow the BootP relay agent to forward DHCP packets, go to the preferred

server prompt (for example,

box; eth 2/2; ip/2.2.2.2/255.255.0.0; bootp;

relay-agent

) and enter:

pass-thru-mode

<value>

value

is one of the following:

bootp

(default)

bootp-dhcp

dhcp

For example, the following command line sets the pass through mode to dhcp,

which enables the BootP relay agent on the router to transmit only DHCP packets

to the server.

relay-agent/2.2.2.2/10.10.10.10#

pass-thru-mode dhcp

relay-agent/2.2.2.2/10.10.10.10#
