When assigning IP addresses to an interface, consider the following:
You can assign only one primary IP address to an interface.
The primary and secondary IP addresses can be located in the same network segment.
Before removing the primary IP address, remove all secondary IP addresses.
You cannot assign a secondary IP address to the interface that is configured to borrow an IP
address through IP unnumbered or obtain one through BOOTP, or DHCP.
