Mitigating the effects of SLAAC renumbering events (draft-ietf-6man-slaac-renum)
by Fernando Gont 31 Aug '22

31 Aug '22

Folks, We have been discussing the potential problems associated with SLAAC renumbering events for a while now -- one of the most common cases being ISPs rotating home prefixes, and your devices ending up with stale/invalid addresses. We have done quite a bit of work already: * Problem statement: https://datatracker.ietf.org/doc/html/rfc8978 * CPE recommendations: https://datatracker.ietf.org/doc/html/rfc9096 But there's still some work to do to address this issue: The last remaining it is to improve SLAAC such that hosts can more gracefully deal with this renumbering events. In that light, IETF's 6man has been working on this document: https://www.ietf.org/archive/id/draft-ietf-6man-slaac-renum-04.txt And we have proposed a simple algorithm for SLAAC (an extension, if you wish) that can easily help, as follows: If you (host) receive an RA that contains options, but not all of the previously-received options/information, simply send a unicast RS to the local-router, to verify/refresh that such missing information is still valid. If the information is stale, get rid of it. I presented this algorithm at the last IETF meeting (https://youtu.be/eKEizC8xhhM?t=1308) (You may find the slides here: https://datatracker.ietf.org/meeting/114/materials/slides-114-6man-improvin…) Finally, I've sent draft text for the specification of the algorithm here: https://mailarchive.ietf.org/arch/msg/ipv6/KD_Vpqg0NmkVXOQntVTOMlWHWwA/ We would be super thankful if you could take a look at the draft text (i.e., https://mailarchive.ietf.org/arch/msg/ipv6/KD_Vpqg0NmkVXOQntVTOMlWHWwA/) and provide feedback/comments. If you can post/comment on the 6man wg mailing list (https://www.ietf.org/mailman/listinfo/ipv6) that´d be fabulous. But we'll appreciate your feedback off-line, on this list, etc. (that'd still be great ;-) ) Thanks in advance!

BendTel ASN27008 moving router tonight
by Tim Howe 31 Aug '22

31 Aug '22

Between 9 and 11pm tonight our colo provider must move our router to a new rack. I'll shut down bgp a bit after 9pm and then restore once I verify the router is back up correctly and interfaces are normalized. -- Tim Howe tim.h(a)bendtel.com Data Processing 541-389-8252 BendTel GPG pubkey id: CBDE9FFE

If the hijack was of 44.235.216.0/24, then how did AWS propagate a "more specific" than that? Regards, rfg

IPv6 on Lumen/CL
by Nathan Anderson 29 Aug '22

29 Aug '22

We have a circuit on AS209 that was originally provisioned v4-only. I'm now trying to get Lumen to turn v6 up on it. How long does this typically take? I've had a configuration ticket open for nearly 3 biz days now with no movement (or even acknowledgement). For anybody who has gone through this with them, is this unusual or nah? When they do get around to it, what can I expect in terms of how they will prefer to set this up? Separate BGP session running over v6 itself, or modify existing session to have it also carry v6 NLRIs? Thanks, -- Nathan

VZ FIOS and Intel TCP IPv6 Checksum Offload problems
by Sean Donelan 29 Aug '22

29 Aug '22

Hopefully, my pain will help someone else. I've had sporadic Internet slowdowns and stuck networking since IPv6 was enabled on my FIOS ONT a few months ago. After too much troubleshooting, I found out some older Intel GbE ethernet cards have a IPv6 Checksum Offload incompatibility with certain fiber ONT terminals. As Verizon is enabling IPv6 on its FIOS network, you might find intermittent network problems. Intermittent are the worst kind of problems. In some situations where a client machine is connected via some specific Optical Network Terminals (ONTs), and data is appended after the packet checksum, the network adapter can drop receive packets when using TCP-IPv6 Checksum Offload for receive traffic. Intel published an alert in 2017, but I didn't have IPv6 on FIOS then. https://www.intel.com/content/www/us/en/download/19174/disabling-tcp-ipv6-c… TLDR; turn off TCP IPv6 Checksum Offload Affects all operating systems (Windows, BSD, Linux, etc) using the affected wired Intel ethernet controllers. Not a problem with Intel WiFi.

email spam
by William Herrin 28 Aug '22

28 Aug '22

Hello, To folks at places like Google and Godaddy which have gotten, shall we say, overzealous about preventing spam from entering their systems, consider the risk: https://www.washingtonpost.com/education/2022/08/23/fairfax-county-counselo… "Chesterfield County police said emails notifying Fairfax County Public Schools that an employee was arrested and charged with soliciting prostitution from a minor were not delivered to the school system." Long story short, the pedo kept his school job another year and a half. There was once a time when both the outbound emails and the bounce messages when they failed... worked. It was a spammy place but the important emails got through. Regards, Bill Herrin
