Hi,
What is keeping you from advertising a more specific route (i.e /25's)?
Most large transits and NSPs filter out prefixes more specific than a /24. Conventionally, at least in my experience, /24's are the most-specific prefix you can use and expect that it will end up in most places. Some shops with limited router processing or table storage capacity will filter even more restrictively, so a bigger aggregate is worth announcing as well. Cheers, jof
