1.6.8.1 Relay Agent Information Option
The relay agent information option (option 82) includes additional information about the DHCP relay
agent when forwarding client-originated DHCP packets to a DHCP server. The relay agent will
automatically add the circuit identifier sub-option and the remote ID sub-option to the relay agent
information option and forward it to the DHCP server.
1.6.8.2 Circuit-ID Sub-option
In a Circuit ID agent, sub-option 1 is an ASCII string that identifies the interface on which a client DHCP
packet is received.
1.6.8.3 Remote-ID Sub-option
In a Remote ID agent, sub-option 2 is an ASCII string assigned by the relay agent that securely identifies
the client.
