5-14 December 2002 9700-A2-GB20-20

DHCP Relay Configuration Example

In this DHCP Relay example:

The router is configured as a DHCP relay.

UDP broadcasts received from DHCP clients are converted to routed DHCP

requests and sent to the DHCP server.

The DHCP server is specified.

The command line syntax for this example, where

is the number configured for

the sub-interface, is:

ip dhcp server 155.1.3.254

ip route 155.1.3.254 serial 0.
