Loopback address?

What is the purpose of a loopback address on a router?

loopbacks are always up interfaces.
you can use them to be the source of routing protocol packets or snmp on a multi-interface router so those sessions are not tied to a physical interface.

Awesome, thanks

So basically, the loopback is the management IP address of the router?

basically, a loopback addr is just like you talking to yourself to do something.
