答复: Re: DHCP server issues in cloud data center environment

Steven,

Thanks for your reply. Can the overlapped address ranges be separated by
pool or class?

No. You would need a DHCP instance per overlapping address-space.
DHCPd can only operate on a single address-space.
And you should also look at deploying multiple DHCP servers utilizing
DHCP failover for resilience.
