IETF I-D: "Operational Implications of IPv6 Packets with Extension Headers" (Fwd: [v6ops] WGLC on draft-ietf-v6ops-ipv6-ehs-packet-drops)
by Fernando Gont 20 Oct '20

Folks, FYI. P.S.: The relevant IETF wg list is: https://www.ietf.org/mailman/listinfo/v6ops Thanks, Fernando -------- Forwarded Message -------- Subject: [v6ops] WGLC on draft-ietf-v6ops-ipv6-ehs-packet-drops Date: Mon, 19 Oct 2020 12:35:34 -0700 From: Fred Baker <fredbaker.ietf(a)gmail.com> To: IPv6 Operations <v6ops(a)ietf.org> I'm opening a two week WGLC on draft-ietf-v6ops-ipv6-ehs-packet-drops-01.txt. This draft started in 2015, and was set aside for a while. We took it as a working group draft in July with some additional authors, it has been recently updated in response to issues raised, and the question before the house is whether it is ready for archival state - to become an RFC. There are a number of questions: - do we agree with the language? (there are probably nits to be cleaned up) - do we agree with the concepts as stated? - do we agree with the direction the draft takes us? I think the draft could use a thorough review, and having said that, am asking for volunteers. You don't have to tell me, per se; do the review and post it to the mailing list. Two weeks gets us to November 2. _______________________________________________ v6ops mailing list v6ops(a)ietf.org https://www.ietf.org/mailman/listinfo/v6ops

Cogent Layer 2
by Mike Hammett 20 Oct '20

Are any legitimate beefs with Cogent limited to their IP policies, BGP session charges, and peering disputes? Meaning, would using them for layer 2 be reasonable? ----- Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP

Virginia voter registration down due to cable cut
by Sean Donelan 20 Oct '20

20 Oct '20

On the last day of Virginia voter registration, the state-wide voter registration system experienced a cable cut disrupting access to the state-wide database system. Absent clear and convincing evidence otherwise, the problems will likely be caused by the usual stupid stuff. VITA @VITAagency A fiber cut near Rt. 10 in Chester near the Commonwealth Enterprise Solutions Center (CESC) is impacting data circuits and virtual private network (VPN) connectivity for multiple Commonwealth agencies. VITA @VITAagency Technicians are on site and working to repair the cut; updates will be provided as work progresses.

A study on community-triggered updates in BGP
by Jakob Heitz (jheitz) 20 Oct '20

20 Oct '20

IOS-XR has duplicate update suppression logic for EBGP sessions, not for IBGP sessions. If you are using EBGP and seeing a fault in the duplicate update suppression logic in IOS-XR, please let me know configs and details of the experiment. Regards, Jakob. -----Original Message----- Date: Thu, 15 Oct 2020 18:35:58 -0700 From: Thomas Krenc <tkrenc(a)nps.edu> Dear NANOG, As a team of researchers from NPS and TU Berlin, we are investigating the impact of BGP community attributes on the update behavior between ASes. We find that when a route is associated with multiple distinct community attributes it does not only lead to multiple announcement at the tagging AS, but also at neighboring ASes, if communities are not filtered properly. This behavior is wide-spread. In order to better understand our observations, we have performed a series of laboratory experiments using Cisco IOS, Junos OS, as well as the BIRD daemon. We find that - by default - all tested routers generate announcements with changing community attributes, even when other attributes do not change. In addition, when communities are filtered at egress, Cisco und BIRD send duplicate announcements (Juniper does not). Since our findings are limited to observations in public data as well as few router implementations, we would like to share our research and kindly ask you to have a look at: ??? https://www.cmand.org/communityexploration/ There, we provide some resources documenting our research, as well as open questions. We greatly appreciate any feedback and insights you can offer. Also, please don't hesitate to contact us directly: ??? communityexploration AT cmand DOT org best regards Thomas Krenc Postdoctoral Researcher Naval Postgraduate School

Virginia voter registration down due to cable cut [ID #5475615x3]

---- DO NOT EDIT BELOW THIS LINE ---- Assigned to: BuyGoods Support Again, hopefully Twitter won't fall down again during the evening of November 3rd. The digeratti will lose thier minds. No offense towards our many friends at Twitter, but I think the best thing that could happen would be for Twitter to shut 'er down from November 1 through November 6. Remove one of the primary avenues for rapid disinformation and confusion, and allow tabulations to proceed without extra nonsense. This of course won't happen, but one can dream.

Other SNAFUs, Georgia had technical problems with its voter database systems during the first couple of days of early voting. Expect all sorts of minor problems throughout the election and afterwards. Nonetheless they are unlikely to significantly impact the results (hopefully), but will generate lots of noise. Its not just underfunded state I.T. systems. Even very large social media companies can have technical Oopsies. Again, hopefully Twitter won't fall down again during the evening of November 3rd. The digeratti will lose thier minds. Even if Twitter or another major social media platform does go belly-up, most likely it will be a normal technical problem. Wishing the FBI & CISA & OGAs watch officers a very boring night on November 3rd. In other news, New Zealand is having national elections this weekend. New Zealand is usually ranked in the top 10 best election administrations worldwide. NZ expects to have the majority of ballots counted within 2 hours of their polls closing on Saturday evening. Jealous of the Kiwis and their competently run elections. :-) Team BuyGoods ===============================================================================
