1) 

The response message from a DHCP server typically contains a number of configuration 
parameters (DHCP options) for the Router. The DHCP options include IP network information, 
and also the vendor-specific options. In some cases, the Router is implemented to perform 
user-defined operations (as shown below). You can implement your own treatment of all such 
options. 

2) 

If the Router is functioning as a DHCP client, it must identify itself in option 61 (client-identifier) 
in every DHCP message. DUID/IAID is portion of option 61. 

• Option 60 Vendor ID: The option code 60 used to identify Vendor class. 

• Option 61 IAID: IAID (Identity Association ID) assigns an Identity Association ID to 

individual interfaces. In cases where the device is functioning with a single DHCP client 
identity, it must use value 1 for IAID for all DHCP interactions. In cases where the device is 
functioning with multiple DHCP client identities, the values of IAID have to start at 1 for the 
first identity and be incremented for each subsequent identity. For example, the device may 
use IAID value 1 for the first physical interface and value 2 for the second. Alternatively, the
