To avoid address conflicts, configure the DHCP server to exclude IP addresses used by the
gateway or FTP server from dynamic allocation.
Follow these guidelines when you configure dynamic address allocation:
{ In common address pool view, using the network or network ip range command repeatedly
overwrites the previous configuration.
{ After you exclude IP addresses from automatic allocation by using the dhcp server forbidden-ip
command, neither a common address pool nor an extended address pool can assign these IP
addresses through dynamic address allocation.
{ Using the dhcp server forbidden-ip command repeatedly can exclude multiple IP address
ranges from allocation.
To configure dynamic address allocation for a common address pool:

1208BConfiguring dynamic address allocation for an extended address pool
Extended address pools support dynamic address allocation only.
When configuring an extended address pool, you must specify:
• Assignable IP address range
• Mask
After the assignable IP address range and the mask are specified, the address pool becomes valid.
