Prefix Size Distribution in multiple flavors, on RIPEstat
by Vesna Manojlovic 07 Aug '12

07 Aug '12

Dear colleagues, thanks to the feedback we received after we've published the interactive widget for querying "RIR prefix size distribution" in RIPEstat, we created a follow-up: a dynamically updated web page that gives an overview of IPv4 address space prefix size distribution, per /8: https://stat.ripe.net/specials/registered-ipv4-prefix-size-distribution This page is updated once a day, and is based on statistics published by all 5 RIRs. Possible usage is general research about the distribution of address space, or prefix filtering based on minimum allocation size. If you want to query any other prefix size, and not only /8, or if you want to query for IPv6 space, here is the link to the widget: https://stat.ripe.net/widget/rir-prefix-size-distribution For the background, please find more information in RIPE Labs article about the widget: https://labs.ripe.net/Members/becha/rir-prefix-size-distribution-in-ripestat Looking forward to your comments or questions, regards, Vesna -- Vesna Manojlovic BECHA(a)ripe.net Senior Community Builder +31205354444 for Measurements Tools RIPE NCC http://ripe.net

IETF sidr meeting after RIPE65
by Rob Evans 03 Aug '12

03 Aug '12

Hi, If you haven't yet booked your return travel from Amsterdam for RIPE 65, and are interested in participating in such things, it may be worth noting that there will be an "interim" meeting of the IETF's sidr (Secure Inter-Domain Routing) working group at the same venue on September 29th, i.e. the day after the RIPE meeting finishes. This will be part of a Large Interim Meeting where several other working groups will also be present (although don't ask me which ones). Best regards, Rob

Route flap damping considered usable
by Rob Evans 26 Jul '12

26 Jul '12

All, Those of you that were in Ljubljana will have seen Randy Bush's presentation 'Route Flap Damping Made Useful.' Based on the work behind this, Randy, Cristel Pelsser, Mirjam Kuehne and myself have produced the following document which we'd like to publish as a document of this working group. Please have a look and discuss on this list. I'd also like to remind you that we'll be meeting nine weeks from today in Amsterdam at RIPE65. I should be allowed out for this meeting, so if you have any suggestions for what you'd like to see on the working group's agenda, please send it to Joao and myself via <routing-wg-chairs(a)ripe.net>. Hope you're having a good summer! Rob RIPE Routing Working Group Recommendations on Route Flap Damping Introduction Route Flap Damping (RFD) [1] is a mechanism for BGP speaking routers that penalises prefixes that exhibit a large number of updates (‘flapping’), and suppresses a route when the accumulated penalty exceeds a given threshold. The penalty decays over time until it reaches a lower threshold at which point the route is unsuppressed. RFD is intended to improve the overall stability of the Internet routing table and reduce the load on BGP speaking routers. In ripe-378 [2] it was stated that due to the dynamics of BGP, especially a phenomenon called ‘path hunting,’ the default configurations of flap damping can do more harm than good as it may suppress a prefix after it has only flapped a few times. Consequently RFD was deprecated due to the problem of over damping (see [2] for more details). A small number of prefixes on the Internet continue to flap rapidly and cause a disproportionate number of updates to BGP and load on BGP speaking routers, this document uses experimental data gathered from an operational environment to suggest changes to the RFD parameters to suppress the prefixes that flap the most, while minimising the suppression of other prefixes. This document suggests parameters which would make RFD usable and is based around the work of Cristel Pelsser, Olaf Maennel, Pradosh Mohapatra, Randy Bush, and Keyur Patel presented at PAM2011[3]. History and Background In the early 1990s the accelerating growth in the number of prefixes being announced to the Internet (often due to inadequate prefix aggregation), the denser meshing through multiple inter-provider paths, and increased instabilities started to cause significant impact on the performance and efficiency of some Internet backbone routers. Every time a routing prefix altered state because of a single line-flap, the withdrawal was advertised to the whole BGP-Speaking Zone (BSZ) and handled by every router that carried the full Internet routing table. The load this processing placed on the control planes of routers caused further instability as the routers were not able to process other BGP updates or they dropped traffic transiting the device. This could produce cyclic crashing behaviour. To overcome this situation RFD was developed in 1993 and has since been integrated into most router BGP software implementations. RFD is described in detail in RFC 2439[1]. When RFD was first implemented in commercial routers, vendor implementations had different default values and different characteristics. As this inconsistency would result in different rates of flap damping, and therefore introduce inconsistent path selection and behavior that was hard to diagnose, the operator community introduced a consistent set of recommendations for flap damping parameters, so that ISPs deploying RFD would treat flapping prefixes in the same way. This call for consistency resulted in the RIPE Routing Working Group producing first ripe-178, then ripe-210, and finally the ripe-229 documents [2a]. The parameters documented in ripe-229 were considered, at time of publication in 2001, the best current practice. In 2006, this was reviewed again and resulted in ripe-378 [2] which recommended to disable RFD because it created more harm than good. Analysis In the work by Pelsser et al [3], it is shown that 3% of all prefixes cause 36% of BGP updates, and just 0.01% of the prefixes cause 10% of the BGP updates. The aim is to only penalise those prefixes with excessive numbers of updates. The default values used in current implementations of RFD apply a penalty of 1000 each time a route flaps, and suppresses the prefix when the penalty exceeds a figure in the region of 2000 (Cisco IOS) or 3000 (Juniper JunOS). The table shows the percentage of prefixes above the suppress threshold and the percentage reduction in BGP churn for various values of suppress threshold. The current default suppress value of 2000 reduces BGP churn by 47%, but it suppressed 14% of the prefixes at some point over the lifetime of the experiment. Significantly larger values of suppress threshold such as 12000, 15000 or 18000 still reduced BGP churn, but suppressed far fewer prefixes which it is believed reduces the risk of penalising otherwise well-behaved prefixes. Suppress % prefixes % reduction in BGP churn Threshold suppressed compared with no damping 2000 14 47 4000 4.2 26 6000 2.1 19 12000 0.63 11.26 15000 0.44 9.51 18000 0.32 8.12 Recommendations In order to punish the biggest offenders - those prefixes that flap the most – yet without punishing others, the RIPE Routing-WG recommends vendors raise the maximum suppress threshold in router implementations to 50,000 and operators configure a suppress threshold value of at least 6,000. The vendors might also change the default suppress threshold to 6,000. But this might surprise operators who use the defult. This has a number of advantages: • it is easy to implement • it will reduce the churn compared to the situation we have now where no RFD is applied • it spares the smaller offenders. Changing the default suppress threshold could result in an increase in forwarding table size or announcement rate for operators who use RFD with the default settings. This warrants further discussion.

A /48 is the minimum assignment size for IPv6 PI and IXP assignments.

RIPE 555 is not a RIPE Policy document but a RIPE NCC organisational document. The scope of this document is to list the address space managed by the RIPE NCC. > So, I guess I'm just thoroughly confused. Can somebody help > me understand what exactly RIPE-555 means? > I apologise if I have not been clear about the changes. I will try to clarify further. RIPE 510 listed only the /8s allocated to the RIPE NCC by IANA. With RIPE 555, our aim is to provide the full and current list of all address space managed by the RIPE NCC, therefore increasing the quality of the data provided. Please also note that not all blocks allocated to the RIPE NCC from IANA in the past are still fully managed by the RIPE NCC. Some IP address space was transferred to AFRINIC, for example. For this reason, we removed the static list and refer to the extended FTP stats, which contain accurate and up-to-date information. This is also the reason why the route sets for these /8s in the RIPE Database (see section 1 of RIPE 510) will be removed. I hope this clarifies. If not, please don't hesitate to contact me. Best regards, Andrea Cima RIPE NCC
