Consistent routing policy?


In reviewing our BGP routing policies last week, I realized that we are
advertising our address space upstream in slightly different ways to our
two upstream providers.  For example, we might advertise a /21 to one
provider and break that into two /22s when advertising it to the other.
(The reason this was done was to help with traffic engineering--we'd
prepend one of the /22s to help balance the traffic.  Prepending the entire
/21 might have been too much.)

I'm just wondering if that's acceptable practice, or if we should advertise
consistent prefixes between providers?
