Let's not forget about the use of VRF's.  BGP is not used exclusively for
sending public routes in our network.  Just a thought.

I've never subscribed to the "Are you sure?" concept, or preventing
problems
by removing functionality, effectively tying an operator's hands behind
his/her back.  The fact is that redistributing BGP into an IGP can have its
uses (though not usually, okay, never, when carrying a full table on the
public Internet) and I'd hate to see the messy workarounds that would come
about, when the solution could otherwise be straightforward.

My Windows workstation asks me "Are you sure?" all the time.  Just
annoying,
really.

Should the Service Provider version of routing software include the
redistribute bgp command?  Other than CCIE labs, I haven't seen a
real-world use for redistributing the BGP route table into any IGP.

If the command was removed (or included a Are your sure? question) what
would the affect be on ISPs, other than improving reliability by
stopping network engineers from fubaring a backbone?
