Route Flap Damping
by Rob Evans 25 Oct '12

25 Oct '12

All, As Joao mentioned during our meeting in Amsterdam, we'd like to move this document towards a last call in the working group and publish it as a WG document. Appended to this message is the current version (the only difference to the one circulated in July is a change from a comma to a full stop). The last call will run for four weeks from today. Many thanks, 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.

If you are using APNIC as an RPKI trust anchor, please update your Trust Anchor Set.
by George Michaelson 15 Oct '12

15 Oct '12

If you are using APNIC as an RPKI trust anchor, please update your Trust Anchor Set. APNIC will be switching to a new RPKI 'split' trust anchor system on the 25th of October. This change is needed to align APNIC administered resources with their allocation hierarchy. These resources will also be certified under each responsible parent registry at the appropriate time. In accordance with RFC6490 the old APNIC Trust Anchor Locator, associated certificate and repository will be removed, when the certificate expires on the 28th of October. 5 new Trust Anchor Locator (TAL) have been published. These will be kept up to date as an independent trust anchor set for resources maintained by APNIC. The production cycle will start on the 25th of October. Relying parties must add these new TAL by the 25th of October in order to maintain continuity of validation. If you have any questions please contact me. George Michaelson (ggm(a)apnic.net) Please add the following to your trust anchor set: rsync://rpki.apnic.net/repository/apnic-rpki-root-afrinic-origin.cer MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAuMLL96YV9pf0rZ4Ow/bk cgpoPfsRzkcgmisyCuMUdotHwrp8pepujhohatScRK09ILRrZYCdpX4121MJhqXC P3u3hy9fF0CeARKX/Q82nJccD4dtUp23UcFys8hwJgNYZI910ajkAxwNT//H/TFw oUYbzZGBR7o2awMc7GdQl/j6dgOkV6AfYy5DyDEgOUNHnUxED2rreefL/E2Fr2ST Esar6bTR4Tg4+nVF1PjAkgN0tKZYe4wZ6VmtqV/VTngSLysim6av7ki+JR3cVgVU OqXeh1vPjH2tNu6u9bX37ZrdVb6NBRer9I99IDbKvyhELb6nzo8+Q74zga9HI+Pf QwIDAQAB rsync://rpki.apnic.net/repository/apnic-rpki-root-arin-origin.cer MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAp6vscYtzhe0CfFk5Ro44 llPhsInXtfAxqfYmK7m9V3khkqK3d3/ZAW6pcJm7qW8XhEGl+F5mUeeLIm5JoIhr kT5B5M6uL0VlCCkZJH4h76ybOa83vWITNZEDy9L3c3nK4S+Basu3vYoE4ICXGG+J 7zg5Iw9saV+p03E2w1g16pt1QI3Cnggp6edkeWClEz3aPw/ULOIHb7YmatWwdERl tL9LsuMSKszQLUY7F4XVpxey/rJYAZgzDUh+b6813WAClCkkydNjsbviuekAWJbx sW7Mcw53u30K4g8MP03CjkDOubyoR4Qo99R1UQJCdrRsFKbSSfN/fOA4y7ikc3xs jQIDAQAB rsync://rpki.apnic.net/repository/apnic-rpki-root-iana-origin.cer MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAx9RWSL61YAAYumEiU8z8 qH2ETVIL01ilxZlzIL9JYSORMN5Cmtf8V2JblIealSqgOTGjvSjEsiV73s67zYQI 7C/iSOb96uf3/s86NqbxDiFQGN8qG7RNcdgVuUlAidl8WxvLNI8VhqbAB5uSg/Mr LeSOvXRja041VptAxIhcGzDMvlAJRwkrYK/Mo8P4E2rSQgwqCgae0ebY1CsJ3Cjf i67C1nw7oXqJJovvXJ4apGmEv8az23OLC6Ki54Ul/E6xk227BFttqFV3YMtKx42H cCcDVZZy01n7JjzvO8ccaXmHIgR7utnqhBRNNq5Xc5ZhbkrUsNtiJmrZzVlgU6Ou 0wIDAQAB rsync://rpki.apnic.net/repository/apnic-rpki-root-lacnic-origin.cer MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAyoYPp3l3DWyPtLWrmRn4 Oux9hQ5bxd0SX/f6ygHxik+I3eMJP5J0Pr2e500tyXb2uKsX9kDqu/kckr+TUMhV BHd5yAv8OAE3YYEvpz/7uTX7cYy2yUeA76OEP75Y88OIQEzGpPLNpIzDxMggxuDh IhkA5xMiUJgVoEgmWSzR+MuRBjv2422wAGB5GpLgYsOjpwvG0VPmhnE+39+10ucQ CLt0Ny5kOR4an2tkvHjm7rzKDnFm8MWxPzAWESdf+8g7ITzSglqxDNiK5E5rdzNt h1Kvp+9RwaFArw6Ky1A4HhnoplN4EfKwxq0YamuKV0ZTTpWyT2+qDuE6sOfHRbJ0 5QIDAQAB rsync://rpki.apnic.net/repository/apnic-rpki-root-ripe-origin.cer MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAwsQlXmEklLYApoDo7GEa NNTEGFPU5wJpi04iXuga2xn+g/TMLOlyJbjuPYRtRm/7VbRnN3m9Ta+WETy03+Fm EbXzB4xxhJKVik/ARHBnrBWhLyURy8Q5/XplE9cJein37IE1mIsbKM7o/90S225w 7GuvW7T4kjPWYmBFOywHWsfQO1EdsgiJrkz+Ab67ZkdSIiKHkf2UE6/MrbDEj+QK 9+s/vKH8BtDhaLmTWY+bVvfJ3+AWDH6roo1ozbl5yamQFbLOl3ns30f3yOJcNSNu /qgMQRRyp2sXXQovhTy8yqm3LFspaCWnTmQtBieWZwibuOa4Z27A1FzTMst2T4wY /wIDAQAB
