Has anyone noticed any issues resulting from the increase? No http://www.cidr-report.org/as2.0/#General_Status But quite interestingly seems like something went wrong with AS13184 around 12:00 UTC. https://stat.ripe.net/AS13184#tabId=routing Regards, Aftab A. Siddiqui

RE: So Philip Smith / Geoff Huston's CIDR report becomes worth a good hard look today
It looks great though I would not want to troubleshoot the RIB to FIB programing errors unless there's a note somewhere saying what abbreviation to search for in FIB. The other think that comes to mind is that the more specifics could have different backup next-hops programed. adam From: NANOG [mailto:nanog-boun...@nanog.org] On Behalf Of Brett Frankenberger Sent: Thursday, August 14, 2014 4:50 AM On Wed, Aug 13, 2014 at 07:53:45PM -0400, Patrick W. Gilmore wrote: you mean your vendor won't give you the knobs to do it smartly ([j]tac tickets open for five years)? wonder why. Might be useful if you mentioned what you considered a smart way to trim the fib. But then you couldn't bitch and moan about people not understanding you, which is the real reason you post to NANOG. Optimization #1 -- elimination of more specifics where there's a less specific that has the same next hop (obviously only in cases where the less specific is the one that would be used if the more specific were left out). Example: if 10.10.4.0/22 has the same next hop as 10.10.7.0/24, the latter can be left out of TCAM (assuming there's not a 10.10.6.0/23 with a different next hop). Optimization #2 -- concatenation of adjacent routes when they have the same next hop Example: If 10.10.12.0/15 and 10.10.14.0/15 have the same next hop, leave them both out of TCAM and install 10.10.14.0/14 Optimization #3 -- elimination of routes that have more specifics for their entire range. Example: Don't program 10.10.4.0/22 in TCAM is 10.10.4.0/23, 10.10.6.0/24 an 10.10.7.0/24 all exist Some additional points: -- This isn't that hard to implement. Once you have a FIB and primitives for manipulating it, it's not especially difficult to extend them to also maintain a minimal-size-FIB. -- The key is that aggregation need not be limited to identical routes. Any two routes *that have the same next hop from the perspective of the router doing the aggregating* can be aggregated in TCAM. DFZ routers have half a million routes, but comparatively few direct adjacencies. So lots of opportunity to aggregate. -- What I've described above gives forwarding behavior *identical* to unaggregated forwarding behavior, but with fewer TCAM entries. Obviously, you can get further reductions if you're willing to accept different behavior (for example, igoring more specifics when there's a less specific, even if the less specific has a different next hop). (This might or might not be what Randy was talking about. Maybe he's looking for knobs to allow some routes to be excluded from TCAM at the expense of changing forwarding behavior. But even without any such things, there's still opportunity to meaningfully reduce usage just by handling the cases where forwarding behavior will not change.) -- Brett

Everything has pluses minuses. The as7007 debacle was actually made far, far worse by Sprint's policies at the time, including a -smb (thanx, Dorian) build. Vinny may have made a major boo-boo by pumping BGP through RIPv1 then back into BGP, but the fact Sprint filtered only on AS path _and_ had an IOS which ignored withdrawals was the real killer. Let's work on the primary protection of the INTERNET. When you were at Verio, you were driving a policy that you wanted, despite being clearly and objectively a tiny minority of the population in question. It might have made the Internet safer, but it had lots of bad side effects, including making it so that large networks have an advantage over small ones. Since those small networks are frequently the people paying the bills, and I am here to make money, I am not terribly happy with such policies. A quick list off the top of my head: BCP38, filtering customer announcements properly, putting pressure on networks that needlessly deaggregate, ensuring information (e.g. your 6500 is about to crash) is properly disseminated, etc. These will have far larger impacts, disadvantage no one, and will not lose you business like your previous policies did. Everyone wins. All that said, I still abide by my primary rule: Your network, your decision. I am arguing for things we can all agree help everyone, not a select few.

When ACL112 came into being, there were old equipment that were being protected by the /19 filters. However, the filters were in place long after those equipment were replaced. This was done for commercial reasons, not to protect the Internet. You know it, I know it, and I'm pretty sure the statute of limitations has expired, so now everyone can know it. Randy may have created Verio's filters for the good of the Internet (even though I disagree, as I just posted), but Sean's reasons for keeping those filters were absolutely not so pristine. -- TTFN, patrick

I think you mean what is best described here: http://www.swinog.ch/meetings/swinog7/BGP_filtering-swinog.ppt --Aris Suresh Ramasubramanian mailto:ops.li...@gmail.com Thursday, August 14, 2014 04:59 Swisscom or some other European SP has / used to have a limit where they would not accept more specific routes than say a /22 from provider x, so if you wanted to take a /24 and announce it you were SOL sending packets to them from that /24 over provider y. Still, for elderly and capacity limited routers, that might work. On Thursday, August 14, 2014, Brett Frankenberger rbf+na...@panix.com Brett Frankenberger mailto:rbf+na...@panix.com Thursday, August 14, 2014 04:49 Optimization #1 -- elimination of more specifics where there's a less specific that has the same next hop (obviously only in cases where the less specific is the one that would be used if the more specific were left out). Example: if 10.10.4.0/22 has the same next hop as 10.10.7.0/24, the latter can be left out of TCAM (assuming there's not a 10.10.6.0/23 with a different next hop). Optimization #2 -- concatenation of adjacent routes when they have the same next hop Example: If 10.10.12.0/15 and 10.10.14.0/15 have the same next hop, leave them both out of TCAM and install 10.10.14.0/14 Optimization #3 -- elimination of routes that have more specifics for their entire range. Example: Don't program 10.10.4.0/22 in TCAM is 10.10.4.0/23, 10.10.6.0/24 an 10.10.7.0/24 all exist Some additional points: -- This isn't that hard to implement. Once you have a FIB and primitives for manipulating it, it's not especially difficult to extend them to also maintain a minimal-size-FIB. -- The key is that aggregation need not be limited to identical routes. Any two routes *that have the same next hop from the perspective of the router doing the aggregating* can be aggregated in TCAM. DFZ routers have half a million routes, but comparatively few direct adjacencies. So lots of opportunity to aggregate. -- What I've described above gives forwarding behavior *identical* to unaggregated forwarding behavior, but with fewer TCAM entries. Obviously, you can get further reductions if you're willing to accept different behavior (for example, igoring more specifics when there's a less specific, even if the less specific has a different next hop). (This might or might not be what Randy was talking about. Maybe he's looking for knobs to allow some routes to be excluded from TCAM at the expense of changing forwarding behavior. But even without any such things, there's still opportunity to meaningfully reduce usage just by handling the cases where forwarding behavior will not change.) -- Brett Patrick W.

BGP routing table growth has been remarkably stable for many years, and most of the older predictive exercises have proved to be reasonably accurate. with all the usual caveats applying to a post-V4-exhaustion world having a lot more uncertainties than before the current figures show that the default free zone in IPv4 will hit 1 million entires in 2019 (http://www.potaroo.net/presentations/2014-02-09-bgp2013.pdf. slide 30). IPv6 is a much less certain exercise. If we take the most extreme picture of of the recent past and apply en exponential growth model to the IPv6 network, then the V6 table gets to 125,000 entries by the same 2019. (slide 34 of the same pack) Frankly, these figures are not particularly alarming at present. Yes, we've crossed over some equipment thresholds in the past (TCAM banks of 256K entires, now 512K and at some point its looking possible that we'll get to 1M entries. If yesterday is a lot like tomorrow then this is some 4 years out for the global routing table if we add the IPv4 and IPv6 tables together. If I were buying equipment today I'd want a minimum of 2M entries in the TCAM on the forwarding cards, and I'd also want to understand my options for field upgrades to at least 4M over the anticipated operational lifecycle of the equipment. But you may have a different crystal ball of course. Geoff

Pruning seemingly redundant entries from BGP is actually impossible to do safely, or if not impossible at least no one has demonstrated a successful algorithm that can prune even a single entry anywhere but the BGP source node or a BGP leaf node. And there's not much point in pruning the BGP RIB at a BGP leaf node -- DRAM to hold the RIB once received and processed is plentiful and inexpensive.

Re: So Philip Smith / Geoff Huston's CIDR report becomes worth a good hard look today
Swisscom or some other European SP has / used to have a limit where they would not accept more specific routes than say a /22 from provider x, so if you wanted to take a /24 and announce it you were SOL sending packets to them from that /24 over provider y.

Once upon a time, Brett Frankenberger rbf+na...@panix.com said: -- This isn't that hard to implement. Once you have a FIB and primitives for manipulating it, it's not especially difficult to extend them to also maintain a minimal-size-FIB. I would say it is hard to implement, or at least non-trivial. Building a reduced FIB from a given RIB is not hard, but then RIB changes become more complex (possibly significantly so) to process into FIB updates. For example, the control plane receives a BGP update that removes a route from the RIB. Right now, the check is simply was this the best path (and if so, was it in the FIB for systems with RIB-FIB filtering methods). If so, remove it from the FIB. If there's a next-best path in the RIB, add it to the FIB. With a compacted FIB, a RIB update has to check a bunch of different things to see what (if any) FIB updates are required. This could also require other RIB updates (to mark other RIB entries as now in or out of the FIB). The lowest-overhead method would probably be for the control plane to keep a separate (non-compacted) copy of the FIB, with all the pointers to how things were compacted before sending to the forwarding plane compacted FIB. That would take up more control plane RAM (and still add CPU overhead to every RIB change). If you thought things like rpd stalls on JUNOS were fun before, imagine the excitement you could have with FIB compacting! -- Chris Adams c...@cmadams.net

Just as a historical note, Sprint didn't have AGS+ or such equipment that were being propped up by the /19 filters (at least for the vast majority of the filter's existence). Neither did Verio.
