[ixpmanager] Techniques to influence inbound (download) traffic across multiple IXPs with /24 prefixes

[Salvador Bertenbreiter]

Hi everyone,

Hope you’re doing well. I’d like to ask how you approach inbound traffic
engineering (download traffic) when you’re connected to multiple IXPs (some
local, some remote) and you only have small prefixes (e.g., /24), so
announcing more/less specifics isn’t really an option.

In that scenario, what methods have worked for you besides simple AS-path
prepending (e.g., no prepend on local IX, prepend 1 on the closest remote
IXP, prepend 2 on the next, etc.)?

Thanks in advance for any guidance or real-world examples.
