Here's a couple of operational questions for those who build filters from IRRdb's. Background: * peval / rpsl.merit.edu *may* be incorrectly evaluating RIPE database entries currently - but this isn't my main thrust. The scary thing is suddenly what I'm 99% sure used to work (expanding AS Macros) now silently fails if they are in RIPE. [for details see the end] * I'm not saying the server is broken (I guess it has something to do with the 'server is running at low priority' line), but if I had this in an automatic filter generating run, it would generate the RADB stuff just fine, and silently filter out all RIPE based peerings. Even if it's working perfectly correctly, the questions are still interesting, at least to me. Questions: * Does anyone actually do build filters without running their own complete database mirror, i.e. do they rely real time on a database working. If so, which one? * Does anyone let this config their routers automatically? To peers customers, transits, or all three? Or do you rely on humans to reinstall the lists once autogenerated? * If it's just a fact of life that occasionally this thing turns up duff data, and if people are in general doing automatic installation, what data validation heuristics are used? I'll summarize to the list any off-list replies that are interesting. -- Alex Bligh GX Networks (formerly Xara Networks) Boring details: [ If anyone from merit/isi is interested this is peval (RAToolSet v4.3.1) binaries from the isi site running on Solaris 2.5.1 and I'm sure it was working a little while ago. I can't get peval to produce anything sensible at the moment for anything in a database other than RADB. For instance: opal[amb].158$ ./peval -no-as -T all AS-EUNET Whois: Open rpsl.merit.edu, 43, RADB,MCI,RIPE,ANS,CANET Whois: WriteQuery -V RAToolSet4.3.1 --single --silent -k -r -s RADB,MCI,RIPE,ANS,CANET -u -T as-set AS-EUNET Whois: Response % RIPEdb(3.0.0a13) with ISI RPSL extensions % Server is running at low priority for -M, -m and -k queries % No entries found in RADB, MCI, RIPE, ANS and CANET database. NOT ANY A 'whois -h whois.ripe.net AS-EUNET' demonstrates that this isn't in fact the case. Works for anything in RADB, including my macros which are in both. As I said, I'm not saying the server is broken (I guess it has something to do with the 'server is running at low priority' line), but if I had this in an automatic filter generating run, it would generate the RADB stuff just fine, and silently filter out all RIPE based networks ] -- Alex Bligh GX Networks (formerly Xara Networks)
