Thomas,

That is exactly what I mean ... a group of subnets on a single interface.
In some instances, we also will deny unknown-clients from some of the
subnets forcing unknown-clients into a certain subnet.

This also applies to DHCPv6 moving forward.  We need to be able to have
multiple subnets grouped together on a remote interface.  We may deny
unknown-clients from some subnets forcing them to other subnets.

Please note that all of the above will occur via relay forwarding as the
DHCP servers are centrally located.
