NOTE:
If a DHCP relay agent exists between the DHCP server and client, the DHCP server, regardless of whether
the subaddress keyword is used, will select an IP address from the address pool containing the primary IP
address of the DHCP relay agent's interface (connected to the client).
Applying an extended address pool on an interface
After you create an extended address pool and apply it on an interface, a DHCP server, upon receiving
a client's request on the interface, attempts to assign the client the statically bound IP address first and
then an IP address from the specified address pool. If no IP address is available, address allocation fails,
and the DHCP server will not assign the client any IP address from other address pools.
To apply an extended address pool on an interface:
