Ohio,
I have tried this on externally distributed routes
(via redistribution) and via internal (another area).
For the externally redistributed routes I used "no
discard external" and for the internal used "no
discard internal".
They both got rid of null entries in their routing
tables, and their summaries were still propagated.
So it all worked well.
Your experience is strange and goes against the grain.
Maybe do a bit more checking with your config etc. or
if you can post it. Or do a console log so we can see
what happens when you insert the command.
