It sounded to me as if it's "evil" when used for connected networks because
it inserts the connected network as "external" which results in incorrect
costs and advertisements and, I suppose, general confusion when reading the
ospf database.
Don't know how to get the connected routes into OSPF if OSPF fails to pick
them up, though.. Nobody has been clear on how to do that!

By what other method, short of a static routes, which to a dynamic
protocol are just as bad, do you insert routes for all your connected
interfaces? IMHO it's a very useful comand when you want all your
interfaces to be advertised but do not necessarily run OSPF on all of
them. Or, for that matter, interfaces that run other IGPs.
I've never heard of this being an issue, I'd be interested to hear why
it is such an "evil" command?
