Statement introduced in Junos OS Release 9.3 for EX Series switches.
Insert the suboption of DHCP option 82 (also known as the DHCP relay agent
remote-id
information option) in DHCP request packet headers before forwarding or relaying
requests to a DHCP server. This suboption provides a trusted identifier for the host system
that has forwarded or relayed requests to the server.
The remaining statements are explained separately.
If remote-id is not explicitly set, no remote ID value is inserted in the DHCP request packet
header. If the option is specified but is not qualified by a keyword, the MAC
remote-id
address of the host device (the switch) is used as the remote ID.
