4.3.4 DHCP Relay and Option 82
The Relay Agent Information option (Option82) is inserted by the DHCP relay agent when forwarding client-originated DHCP
packets to a DHCP server (RFC 3046). Servers recognizing the Relay Agent Information option may use the information to
implement IP address or other parameter assignment policies. The DHCP Relay can forward the DHCP broadcast packets to a
DHCP server in a different subnet (RFC 1542). So DHCP server can provide IP addresses to clients spanning multiple subnets
instead of deploying a DHCP server on every subnet.
4.3.4.0DHCP Option82
To enable DHCP option82 function, need to enable global option82 and special port option82. Then select DHCP router port.
