Configuration Example — DHCP Server and Relay Agent
In the following example, a DHCP address pool is created for PCs on the 10.1.3.0 network. In this pool, all
addresses except the excluded address, which is the router's IP address, are available to the DHCP server
for assigning to clients.

command to verify the DHCP Relay Agent configuration, as shown in
.
Purpose
Enter the IP address of the DHCP server.
Enable forwarding of BootP/DHCP requests. By default, the
DHCP relay agent feature is disabled.
(Optional) Configure the maximum allowable relay agent hops.
The parameter has a range of 1 to 16. By default, the packet will
be forwarded a limit of four hops.
(Optional) Configure the minimum wait time in seconds for
BootP/DHCP relay requests. When the BootP relay agent receives
a BOOTREQUEST message, it may use the
seconds-since-client-began-booting field of the request as a factor
in deciding whether to relay the request or not. The parameter has
a range of 0 to 100 seconds. The default value is 0 seconds.
