That is my current situation.  Some zones are nailed down with static assignments while others (used for more transient purposes) use DHCP to get their configuration.

So you have zone "D" serving DHCP, and zones "A" and "B" which are DHCP clients, right?

Unless you have a bizarre circular dependency ("A" serves something to "D" and vice-versa), I believe you're okay.  A dhcp configured interface launches dhcpagent, and networking for that interface is down until it hears from the DHCP server.  Other parts of the zone boot keep plowing.

The ONLY POSSIBLE gotcha I can think of is if intra-zone broadcast is buggy, and I don't think it is. If it's buggy, we need to fix it.
