A non-existing address pool can be applied to an interface, but the server cannot assign any prefix,
address, or other configuration information from the address pool until the address pool is created.
Examples
# Apply address pool 1 to GigabitEthernet 2/1/1, configure the address pool to support desired
address/prefix assignment and address/prefix rapid assignment, and set the preference to 255.

Parameters
start-ipv6-address: Specifies the start IPv6 address.
end-ipv6-address: Specifies the end IPv6 address, which cannot be lower than start-ipv6-address. If you
do not specify an end IPv6 address, only the start IPv6 address is excluded from dynamic allocation. If
you specify an end IPv6 address, the IP addresses from start-ipv6-address through end-ipv6-address are
all excluded from dynamic allocation.
Usage guidelines
You can exclude multiple IP address ranges from dynamic allocation.
The IPv6 addresses of some devices such as the gateway and FTP server cannot be assigned to clients.
Use this command to exclude such addresses from dynamic allocation.
If the excluded IPv6 address is in a static binding, the address can still be assigned to the client.
The address or address range specified in the undo form of the command must be the same as the
address or address range specified in the command. To remove an IP address that has been specified as
part of an address range, you must remove the entire address range.
