why do we use option 82
Option 82 was designed to allow a DHCP Relay Agent to insert circuit specific information into a request that is being forwarded to a DHCP server.Specifically the option works by setting two sub-options: Circuit ID and Remote ID.ike I said in an earlier reply, I usually see people removing this option in most cases due to the fact that they are trying to use DHCP snooping and don't want option 82 confusing their servers. says: December 21, 2007 at 10:38 am. I have worked with the server side, specifically ISC's dhcpd.
