DHCP Relay Agent

The router provides the capability of serving as a DHCP Relay Agent, as specified
in RFC 2131, Dynamic Host Configuration Protocol. The router provides the
capability to enable and disable the DHCP Relay Agent and to configure the IP
address of the DHCP server to which the DHCP requests are to be forwarded.

The DHCP server assigns an IP address to the end-user system. When DHCP
Relay is enabled, it is possible to limit the number of DHCP clients. The IP Routing
Table and ARP Table are automatically updated. The DHCP relay agent in the
router should be used when there is a DHCP server upstream in the service
domain.

DHCP relay agent setup considerations include the following:

DHCP server IP address must be configured.

DHCP relay and routing must be enabled; that is, both the server address and
the interface closest to the server are configured.

The number of DHCP clients can be limited to 1–256.

DHCP server and DHCP relay functions cannot be enabled at the same time.

NAT and DHCP relay cannot be enabled at the same time.
