Hierarchy Level (EX Series, QFX Series)

Hierarchy Level (MX Series)


Have the device insert DHCP option 82 (also known as the DHCP relay agent information option) information in the DHCP request packet header of a DHCP request that it receives from a DHCP client connected to one of its interfaces before it forwards or relays that DHCP request to a DHCP server. The server uses the option 82 information, which provides details about the circuit and host the request came from. However, in formulating the reply, the server does not make any changes to the option 82 information in the packet header. The device receives the reply and then removes the DHCP option 82 information before forwarding the reply to the client.

The remaining statements are explained separately. See CLI Explorer.


Insertion of DHCP option 82 information is not enabled.
