Loopback Interfaces

Router(config)#interface lo0

Moves to virtual interface Loopback 0

Router(config-if)#ip address

Assigns IP address to interface


Loopback interfaces are always "up and up" and do not go down unless manually shut down. This makes Loopback interfaces great for using as an OSPF router ID.
