:-).

Well, in IOS, you can pretty much apply lots of things that 
don't exist, much to the detriment of the network.

Many years ago, we dropped a BGP session because someone 
decided to manually type out a prefix list toward a BGP 
customer at the edge which turned out not to exist (well, it 
did, just that the name in the session differed from what 
was actually created), and that caused us to exceed prefix 
maximums with one peer, leading to a session tear down far 
away into the network.

Copy & paste, templates, e.t.c. helps here, but IOS will be 
glad to let you apply several references that don't exist.

I was just surprised to find this still in IOS XR, which 
promised sanity checking on commit.
