[Kea-users] option 54

[Chaigneau, Nicolas]

Option 54 is set automatically by the server (to the IP address on which the packet was received, I think).

It cannot be an arbitrary value, it is used by clients in DHCPREQUEST messages. The server will ignore such messages with an option 54 that does not match its configuration (even if they are unicast to him) because it indicates that the client is trying to communicate with another server.

What are you trying to do exactly ?

Nicolas.
