Can we Bring Down a Loopback Interface?

[rais.ahmad]

Is there any way to bring down a loopback interface on certain events? Can we track it down?

I want to down loopback0 should FastE0/0 goes down.

Thanks.

Any reason why you want to do this ? I doubt if this is possible.

I can tell you certainly from personal experience that if you issue the shutdown command on a loopback interface that it goes into administratively down.

I am not sure that there is any way to do this automated by tracking. But it certainly can be done manually.

You can admin down the interface -

int lo 0

shut

end

but you cannot do anything to shut the interface if another interface does down - why are you trying to d0 this? There is almost definately a better way to do what you are trying to accomplish.
