Table 1-4 Delete IP addresses on the interface
Delete IP addresses on the
interface.
To delete all IP addresses on the interface, execute this command without specifying
any argument.
To delete the main IP address, use the undo ip address ip-address net-mask
command.
To delete subordinate addresses, use the undo ip address ip-address net-mask sub
command.
Before you can delete the main IP address, you must delete all subordinate addresses.
IV. Setting negotiable attribute of an IP address for an interface
If a PPP-encapsulated interface is not assigned an IP address while its peer has been
assigned one, you may configure PPP address negotiation to have it accept the
address assigned by the peer. For example, when accessing the Internet through an
ISP, you may use the ip address ppp-negotiate command to accept the addresses
assigned by the ISP.
Perform the following configuration in interface view.
