Mike,

My guess for dual DHCP servers (not tested):

STEP 1: set up your two DHCP servers; these can be workstations, or Cisco
routers. If routers:

ip dhcp pool DHCP4CCIE
    network 10.1.1.0 255.255.255.0
    domain-name CCIE
    default-router 10.1.1.1
    lease 30
    <etc.>
no ip dhcp conflict logging
ip dhcp excluded-address 10.1.1.1 10.1.1.4

STEP 2: set up pointers on router allocating IPs to clients:

ip dhcp-server 10.1.1.1 (DHCP server doesn't have to be local)
ip dhcp-server 10.1.1.2 (ditto)
interface ethernet 0
    peer default ip address dhcp (allocates the IPs to the clients)
    ip address-pool DHCP4CCIE

STEP 3: If you want to use a router as a client asking for an IP address:

interface ethernet 0
    ip address negotiated

When you get it working, please post your configs. Thanks.

HTH, Kym
