Hierarchy Level


Apply a DHCP relay agent configuration to the named group of DHCP server addresses. The server group itself is configured with the server-group statement. You can apply an active server group globally or for specific groups of interfaces, configured with the group statement. An active server group applied to an interface group overrides a global configuration.



(Optional) (DHCPv4 only) Enable the relay agent to accept and forward a DHCP request (renew or rebind) ACK message to the client from any DHCP local server in the active server group. Starting in Junos OS Release 18.4R1, this option also applies to DHCP information request (DHCPINFORM) ACK messages.

  • Default: Forward ACK messages from only the original binding server.
