companies requiring the longer prefixes. Are there companies that actually announce their smaller routes despite controlling the shorter prefix?
Yes.
What would be the benefit of doing so?
They mistakenly believe that all providers will proagate their more-specifics and want to attranct traffic in a certain way for a certain longest-match. If they - anticipate this link-juggling to ONLY occur along contracted paths - appropriately tag NO-EXPORT - also announce the greater aggregate ...then they'll get what they want out of the parties with whom they contract. It is trivial and stunning that service providers don't actively promote it to their customers. Some would rather collect money for customers grazing on the commons rather than for providing *service*. -- RSUC / GweepNet / Spunk / FnB / Usenix / SAGE
