Filter update procedures

[Jacques Caron <]

Hi,

This is probably a recurring discussion... Feel free to point me to older 
threads on the same subject. Also, the discussion might be more appropriate 
in another forum (routing WG, specific IX mailing lists...)?

The issue is that of route filtering procedures between peers. Some of us 
(especially those that are present on many IXes) receive quite a bunch of 
"please update your filters with AS so and so and routes so and so", but I 
wonder if anyone uses them? I have the feeling most people either:
- don't filter anything
- filter based on IRR (RADB/RIPE DB...) contents (using an as-macro), with 
regular automatic updates

I don't feel manually updated filters are very realistic. I guess a small 
survey on "who needs notification of new announcements" would be a good 
idea... I suspect we'd end up with a very small list.

Some specific field in AS descriptions in the RIPE DB to indicate 
notification of changes would be great too. It would avoid "spamming" 
everybody with the filter updates.

Comments?

Thanks,

Jacques.
