FWIW: I do not use it, and neither do most of the people I know - on
ciscos. On Junipers, apparently they like you to do this, not sure why.
On a cisco, many people say the route is already in the IGP (has to be to
be advertised by BGP), so why not just redistribute with filters. I prefer
to put the prefixes into BGP manually, and nail something to the loopback
for the IGP. If you make a mistake in typing the prefixes in, you get a
single route wrong. If you make a mistake in your filter during
redistribution, all kinds of bad things can happen.
My $0.00000000002.
