Route table growth and hardware limits...talk to the filter
by Jon Lewis 23 Sep '07

23 Sep '07

This evolved from a thread on another list. I think it's more appropriate for nanog, so here it is. Since many of you probably aren't on the other list, some context is lost, but it shouldn't matter. The prefix-list presented below should be considered a proof-of-concept / work-in-progress. As stated below, no testing has been done to verfiy it will cause no loss in connectivity (i.e. due to networks deaggregating their space and announcing it only as longer subnets than their RIR states are the minimum allocation size for the range from which their CIDRs were carved). OTOH, this _should_ be a relatively safe way for networks under the gun to upgrade (especially those running 7600/6500 gear with anything less than Sup720-3bxl) to survive on an internet with >~240k routes and get by with these filtered routes, either buying more time to get upgrades done or putting off upgrades for perhaps a considerable time. Here's what I ended up with (so far) based on Barry Greene's work at ftp://ftp-eng.cisco.com/cons/isp/security/Ingress-Prefix-Filter-Templates/ T-ip-prefix-filter-ingress-strict-check-v18.txt While working on this, I noticed a bunch of inconsistencies in the expected RIR minimum allocations in ISP-Ingress-In-Strict and in the data actually published by the various RIRs. I've adjusted the appropriate entries, and as previously mentioned, flipped things around so that for each of the known RIR /8 or shorter prefixes, prefixes longer than RIR specified minimums (or /24 in cases where the RIR specifies longer than /24) are denied. Due to the number of minimum acceptable allocation inconsistencies, I recollected all the data on number of routes shaved per RIR filter. For some reason, today I started out with fewer routes (228289...yesterday, I started with 230686) with no filtering. RIR filter section Reduction in routes APNIC 16690 ARIN 41070 RIPE 16981 LANIC 4468 AFRINIC 1516 ----------------------------- TOTAL 80725 The end result of applying all the RIR minimum allocation filters was 147564 BGP routes. I haven't checked to make sure there was no loss in reachability...this is just an idle 7206/NPE225 with nothing but its ethernet uplink. The prefix-list I'm using for this experiment is: !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!

Trouble with Marconi ASX-200BX
by Bjoern 21 Sep '07

21 Sep '07

Hi, sorry for a little offtopic. But i don´t knew a better place for hopefully find help. We had a little trouble when trying to configure a "new" Marconi Fore ASX-200BX ATM Switch with an running config from another Marconi ASX-200BX. Some of the config commands, seemed not to be known by the newer Foreos 7.1 on the "new". we tried to do downgrade the Foreos on the "new" Marconi Fore ASX-200BX ATM Switch. Installed was Foreos7.1 on a Pentium based SCP (SCP-ASXp5), careless we decided to delete the whole files and wanted to copy the Foreos7.0 files from another System. We backuped the Files to a tftp server, and then we deleted the folders :( No we have the Problem, that we could not create a folder LD7.0 to copy the files from the other System. And we can´t go back with the saved files, because we was to fast to delete the LD7.1 folder :( We have access to Webfrontend and console. But i´m afraid that the SCP is electronic trash if i try to boot now. I think there are 2 possible solutions to solve our Problem: 1. someone could tell us, how to create a folder and we copy the saved files back to the flash Looking back and thinking about what we have tried, and realization how naive we have acted, in my eyes the best way. 2. We make a "system uprade" and this upgrade will recreate the files. Our Problem with the second solution is, that we can´t find a download link for a System upgrade file, like discriped in the manual. We tried to get an public account for the Software http://tactics.marconi.com/services/index.cgi?loadPage=software/software.cg… But we did not get an answer on our request since more then 2 days. Could anyone help us ? Or did we create electronic trash? thanks Bjoern
