Not including option43(VendorSpecificInformation) when lease

[藤原慎太郎]

Hi, I have a question on option43(VendorSpecificInformation).

How do I lease address not informing
option43(VendorSpecificInformation) from some subnet.

I have 3 subnets making shared-network.

I want to lease address informing option43(VendorSpecificInformation)
to some subnet and not to some subnet.

I have written configuration using class and subclass, and allow / deny in pool.
But not working well (denied altogether).
