Table K-10 Create Router Interface Dialog Box (Continued)

Subinterface ID	Applies only to subinterfaces.
	The ID number of the subinterface.
IP	The source of the IP address for the interface:
	• Static IP—Defines a static IP address and subnet mask for the interface.
	Enter this information in the fields that appear below the option.
	Note You can define the mask using either dotted decimal (for example,
		255.255.255.255) or CIDR notation (/32). See Contiguous and
		Discontiguous Network Masks, page 9-146.
	• DHCP—The interface obtains its IP address dynamically from a DHCP
	server.
	• PPPoE—The router automatically negotiates its own registered IP
	address from a central server (via PPP/IPCP). The following interface
	types support PPPoE:
	–	Async
	–	Serial
	– High-Speed Serial Interface (HSSI)
	–	Dialer
	–	BRI, PRI (ISDN)
	–	Virtual template
	–	Multilink
	• Unnumbered—The interface obtains its IP address from a different
	interface on the device. Choose an interface from the Interface list. This
	option can be used with point-to-point interfaces only.
	Note Layer 2 interfaces do not support IP addresses. Deployment fails if
		you define an IP address on a Layer 2 interface.
