HPE FlexNetwork HSR6800 Configuration Manual page 85

DHCP server still does not respond, the next secondary IP address is used. After the secondary IP
addresses are all tried and the DHCP server does not respond, the relay agent repeats the process
by starting from the primary IP address.
Without this feature, the relay agent only encapsulates the primary IP address to the giaddr field of
all requests.
On a relay agent where relay address pools and gateway addresses are configured, the smart relay
feature starts the process from the first gateway address. For more information about the relay
address pool configuration, see
To configure the DHCP smart relay feature for a common network:
Step
1. Enter system view.
2. Enter interface view.
3. Enable the DHCP relay
agent.
4. Assign primary and
secondary IP addresses to
the DHCP relay agent.
5. Return to system view.
6. Enable the DHCP smart
relay feature.
To configure the DHCP smart relay feature for a network with relay address pools:
Step
1. Enter system view.
2. Enter interface view.
3. Enable the DHCP relay
agent.
4. Return to system view.
5. Create a DHCP relay
address pool and enter its
view.
6. Specify gateway addresses
for the clients matching the
relay address pool.

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.
By default, the relay address pool
does not have any gateway
addresses.
