multipe dhcp pool via same interface

[Glenn Satchell]

Yes, that should do it. Note that where you define the same setting in
more than one subnet defintion, you can move that setting to the global
scope. For example you could define option domain-name-servers in the
global scope (that is outside the subnet definitions) and it would be
inherited by all of them. If one subnet was different you could
override that value by defining it in the subnet.
