12. To verify the tunnel interface, use the show interface tunnel command in
Interface configuration mode, as shown below:
MOT(config-if)#show interface tunnel <n>
where:
n is the tunnel number; valid entries are 0 to 255.
Configuring an Unnumbered Interface
An unnumbered interface is used in point-to-point connections when an IP address is
not required. This enables IP processing on an interface without assigning an explicit
IP address to the interface. You supply the interface location, which is the type and
number of another interface on which the router has an assigned IP address, and this
interface cannot be another unnumbered interface.
Follow these steps to set an unnumbered interface on the POS module:
1. Before configuring the unnumbered interface, a loopback interface must be
configured. Refer to “Configuring a Loopback Interface” on page 5-8 for more
information.
2. Use the end command to go back to Global Configuration mode.
3. Use the interface pos command in Global Configuration mode to enter the POS
interface, as shown below:
MOT(config)#interface pos <slot>/<interface>
where:
slot is the POS interface slot number.
interface is the POS interface number.
Note: An unnumbered interface can only be configured on the POS module.
