Hi Adam

Would that be the      option relay-agent-information

>From man dhcp-options
Examples of encapsulated options in the DHCP protocol as it currently exists include the vendor-encapsulated-options option, the netware-suboptions option and  the  relay-agent-information

Subject: logging relay agent IP address

 I want to log a few specific things about DHCP assignments, and I've got most of what I want.

      log(info, concat( "RID",
                        binary-to-ascii(16,8,":",option agent.remote-id),
                        binary-to-ascii(16,8,":",option agent.circuit-id),

To this I want to also add the IP address of the relay agent we got the initial request from.  I would want something similar to an "option agent.relay-ip".  Is there any such thing?  Is there any other way to log that?

I do of course get "DHCPDISCOVER from <MAC> via <relay agent>" lines, but I was hoping to get everything on one line.  If I can't then I can't, no biggie.
