Enabling and Disabling Insertion of Option 82 Information

To enable or disable insertion of the DHCP relay agent information option (option 82) in packets destined for a DHCP server, include the relay-option-82 statement:




relay-option-82 {



circuit-id {

prefix host-name logical-system-name
routing-instance-name;
}


}

To control insertion of option 82 information globally, include the relay-option-82 statement and subordinate statements at the [edit forwarding-options dhcp-relay] hierarchy level. To control insertion of option 82 information for a named group of interfaces, include the relay-option-82 statement and subordinate statements at the [edit forwarding-options dhcp-relay group group-name] hierarchy level.

To restore the default behavior (option 82 information is not inserted into DHCP packets), include the relay-option-82 statement with no subordinate statements.
