We compare the local IXP Prefix length Announcements to International Looking Glasses. We provide a view of either Shorter, balanced or longer:
- Shorter = Longer IXP Prefix announcement. Therefore International path may be preferred over IXP Path (BAD)
- Balanced = Equal Prefix length announcement. Therefore shortest AS Path (IXP) will be preferred (Best Practice)
- Longer = Shorter IXP Prefix announcement. Therefore IXP path will be preferred at all times. (not recommended)
