Does Windows 2008 R2 support this option?

Hello Everyone.

I have a new client that wants me to enable option 82 on windows 2008 R2 DHCP servers. The network infrastructure is made up of CISCO appliances only and the reason they want to apply option 82 is because of security.

I cannot tell you much about the option but I really need some assistance. Does Windows 2008 R2 DHCP server supports option 82? how to create it.?

Thank you!

Hi,

082 is not an option defined on the DHCP server, and it is rather an option field attached to DHCPDISCOVER and REQUEST packets inserted by a DHCP relay agent.

In newer windows OS, like server 2016, you do not need to configure anything. By default, a 2016 DHCP server will accept and respond to option 82 data.

As far as I know, for server 2008/2008 R2 and server 2003, it is unsupported. They will drop option 82 in the response packets.

So, the recommend way is to update your windows server to newer version.


Best Regards,

Thanks for your help.
After reading the links, it still does not give how to configure that option in Windows 2008 R2 DHCP servers.
From my understanding, there is no need to configure on Windows 2008 DHCP servers if Windows 2008 R2 DHCP supports that option.

Can anyone share whether you need to configure that option in DHCP servers or not?

Thank you!

As far as I know you cannot configure it anywhere on the Windows Server DHCP.

I guess that Windows 2008 R2 should support that option?
