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:
Gxxx-001(super)# interface Vlan 1
//to configure the IP address of the vlan interface:
Gxxx-001(super-if:Vlan 1)# ip address 180.0.0.1 255.255.255.0
Gxxx-001(super-if:Vlan 1)# exit
Gxxx-001# !
//enter the context of the Dialer interface:
Gxxx-001(super)# interface dialer 1
Gxxx-001(super-if:Dialer 1)# dialer string 1 3001
Gxxx-001(super-if:Dialer 1)# dialer persistent delay 1
Gxxx-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:
Gxxx-001(super-if:Dialer 1)# ip unnumbered 1 Vlan 1
Gxxx-001(super-if:Dialer 1)# exit
Gxxx-001(super)# !
The following sample routing table shows how routes discovered on unnumbered interfaces by routing protocols are listed as via routes in the Next-Hop column:
