Mulitple loopback interfaces with IPs in same subnet

[craig.howson]

I have been looking at a cisco lab and it shows a topology which I have tried to mimic on both Packet Tracer and real kit. It states that on a single router the following loopback interfaces should be configured as follows ….

I can configure lo0 but when I then attempt to configure lo1 I get the message…

Router(config-if)#ip add 10.1.1.2 255.255.255.0

% 10.1.1.0 overlaps with Loopback0

And the same with lo2 as it is in the same subnet.

Is there something I am missing or is this a cisco typo?

Probably a typo, as you cannot normally have multiple interfaces in the same network.
