2.5.1 Introduction to DHCP-Server Option 82
If a DHCP server supports option 82, after the DHCP server receives packets
containing option 82 forwarded by the DHCP relay, the DHCP server processes the
packets normally and assigns IP addresses for the clients.
If a DHCP server does not support option 82, after the DHCP server receives packets
containing option 82 forwarded by the DHCP relay, the DHCP server does not process
the packets.
For details of option 82, see section
