Loopback Interfaces
A Loopback interface is a virtual interface in which the software emulates an interface. Packets routed to
it are processed locally.
Because this interface is not a physical interface, you can configure routing protocols on this interface to
provide protocol stability. You can place Loopback interfaces in default Layer 3 mode.
To configure, view, or delete a Loopback interface, use the following commands.
Enter a number as the Loopback interface.
CONFIGURATION mode
interface loopback number
The range is from 0 to 16383.
View Loopback interface configurations.
EXEC mode
show interface loopback number
Delete a Loopback interface.
CONFIGURATION mode
no interface loopback number
Many of the commands supported on physical interfaces are also supported on a Loopback interface.
Null Interfaces
The Null interface is another virtual interface. There is only one Null interface. It is always up, but no
traffic is transmitted through this interface.
To enter INTERFACE mode of the Null interface, use the following command.
