Release Information
Statement introduced in Junos OS Release 8.3.
Statement introduced in Junos OS Release 12.3 for EX Series switches.
Description
Enable or disable the insertion of the DHCP relay agent information option (option 82) in DHCP packets destined for a DHCP server.
If you enable insertion of option 82 information in DHCP packets, you must specify at least the circuit-id statement to include the Agent Circuit ID suboption (suboption 1) of the DHCP relay agent information option.
You can use the relay-option-82 statement and its subordinate statements at the [edit forwarding-options dhcp-relay] hierarchy level to control insertion of option 82 information globally, or at the [edit forwarding-options dhcp-relay group group-name] hierarchy level to control insertion of option 82 information for a named group of interfaces.
To restore the default behavior (option 82 information is not inserted into DHCP packets), use the delete relay-option-82 statement.
The remaining statements are explained separately.
