Unnumbered IP examples

In the following example, a VLAN interface is configured, and then the Dialer interface is

configured with an unnumbered IP address, borrowing the IP address from the VLAN interface.

//enter the context of vlan interface 1:

G250-001(super)# interface Vlan 1

//to configure the IP address of the vlan interface:

G250-001(super-if:Vlan 1)# ip address 180.0.0.1 255.255.255.0

G250-001(super-if:Vlan 1)# exit

//enter the context of the Dialer interface:

G250-001(super)# interface dialer 1

G250-001(super-if:Dialer 1)# dialer string 1 3001

G250-001(super-if:Dialer 1)# dialer persistent delay 1

G250-001(super-if:Dialer 1)# dialer modem-interface USB-Modem

//to configure IP unnumbered on the Dialer interface, borrowing the IP address

from vlan interface 1, configured above:

G250-001(super-if:Dialer 1)# ip unnumbered 1 Vlan 1

G250-001(super-if:Dialer 1)# exit

G250-001(super)# !
