[ no ] set dhcp relay broadcast-flag-replies
Command introduced in JunosE Release 8.1.0.
Configures DHCP relay and DHCP relay proxy to use the setting of the broadcast flag in
the DHCP request packet to control how DHCP Offer reply packets and ACK and NAK
reply packets are transmitted to DHCP clients during the discovery process. If the
broadcast flag is set in the request packet, DHCP relay and DHCP relay proxy broadcast
DHCP reply packets to clients. If the broadcast flag is not set in the request packet, DHCP
relay and DHCP relay proxy use the layer 2 unicast transmission method to send DHCP
reply packets using the client's layer 2 (MAC) address and layer 3 (IP) unicast address.
The no version causes the router not to use the broadcast flag setting and restores the
default behavior, which broadcasts DHCP Offer reply packets and ACK and NAK reply
packets to all clients during the discovery process.
NOTE: The set dhcp relay broadcast-flag-replies command and the set dhcp
relay layer2-unicast-replies command are mutually exclusive. If you attempt
to issue the set dhcp relay broadcast-flag-replies command when the set
dhcp relay layer2-unicast-replies command is already in effect, the operation
fails and the router displays an error.
