By default, an interface operates in
the DHCP server mode when DHCP
is enabled.

5. Create a DHCP relay
address pool and enter its
view.
dhcp server ip-pool
pool-name
By default, no DHCP relay address
pool exists.
This command is the same for
creating DHCP address pools on a
DHCP server. However, the relay
address pool names are not
necessarily the same as the server
address pool names.
6. Specify gateway addresses
for the clients matching the
relay address pool.
gateway-list
ip-address&<1-64>
[
export-route
]
By default, the relay address pool
does not have any gateway
addresses.
7. Specify DHCP servers for
the relay address pool.
remote-server
ip-address&<1-8>
By default, the relay address pool
does not have any DHCP server IP
addresses.
You can specify a maximum of eight
DHCP servers for one relay address
pool for high availability. The relay
agent forwards DHCP-DISCOVER
and DHCP-REQUEST packets to all
DHCP servers in the relay address
pool.
