          Certainly a case can be made for the use of the redistribute bgp
command when it comes to route-reflection and confederations.  I know of a
couple enterprises that make use of the command in order to maintain
consistent route information throughout their core(which happens to run
eigrp). As well, depending on the size of the enterprise this could prove to
be a valuable asset.

I think the command itself provides the same funcionalty as cisco "backdoor"
command in that it allows for the mistakes made by man, since
computer(routers) don't make mistakes..:-)  This really come down to the
orginal design of the network and if the "requirements" were completely
identified before implementation, unlike the real world scanerio which is
normally the opposite.
