# set dhcp relay layer2-unicast-replies

#### Syntax

[ no ] set dhcp relay layer2-unicast-replies

#### Release Information

Command introduced in JunosE Release 7.2.0.

#### Description

Configures DHCP relay and DHCP relay proxy to use the optional layer 2 unicast and layer 3 broadcast transmission method to transmit DHCP Offer reply packets and ACK reply packets to DHCP clients during the discovery process. The no version restores the default method that broadcasts DHCP Offer reply packets and ACK reply packets to all DHCP clients during the discovery process.

| Note: The set dhcp relay layer2-unicast-replies command and the set dhcp relay broadcast-flag-replies command are mutually exclusive. If you attempt to issue the set dhcp relay layer2-unicast-replies command when the set dhcp relay broadcast-flag-replies command is already in effect, the operation fails and the router displays an error.

#### Mode

Global Configuration
