Sorry for the late response. We use the "Please update filters" messages from our peers as follows: Upon receipt of such a message, we regenerate the filters from IRR information. Then we either confirm that we now accept the routes mentioned in the message, or we ask the peer to put them in the IRR. -- Simon. SWITCH (AS559)

We regenerate all filters, but we only upload them on the router(s) on which we connect to the peer who sent us the message. > I.e. do you NEED the messages, or is it just an additional layer of > sanity checking? We don't really need them, but if a peer wants us to accept newly ASes quickly, and they haven't already been in the IRR for some time, they should mail us. -- Simon.

Filter update procedures
by Jacques Caron 25 May '00

25 May '00

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?

Hi all, Well, if you were in Budapest you will have seen that I had to fly through that presentation very quickly as we were pressed for time, so I'll quickly recap.... The main points are that this needs your input as well, but I'll be happy to bring at all together. If there's something not there that you think should be there, or if any of you have any ideas about anything else to go on, or want to help drawing up one or more of the specs, please let me know. Please feel free to catch me off-line in the bar if you are at the meeting :-). Regards, Mike -- Mike Hughes Senior Network Engineer London Internet Exchange mike(a)linx.net http://www.linx.net/ "Only one thing in life is certain: init is Process #1"
