Enabling the DHCP relay agent on an interface
With the DHCP relay agent enabled, an interface forwards incoming DHCP requests to a DHCP
server.
An IP address pool that contains the IP address of the DHCP relay interface must be configured on
the DHCP server. Otherwise, the DHCP clients connected to the relay agent cannot obtain correct IP
addresses.

Specifying DHCP servers on a relay agent
To improve availability, you can specify several DHCP servers on the DHCP relay agent. When the
interface receives request messages from clients, the relay agent forwards them to all DHCP
servers.
