Anyone using Cogent Ethernet
by Mike Hammett 28 Jan '18

28 Jan '18

I much prefer using WDM transport as opposed to Ethernet\VPLS transport due to it being significantly harder (I try not to say impossible) to oversubscribe. That said, it isn't always available at a decent rate at a given location. Cogent has a reputation (right or wrong) for running things a little hot. Have any of you used Cogent Ethernet\VPLS services? What are you experiences? Offlist is fine if you don't want it public. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest-IX http://www.midwest-ix.com

evil ipv6 bit?
by Baldur Norddahl 26 Jan '18

26 Jan '18

Hello After some apparently unrelated changes, one of my routers stopped routing traffic to a few IPv6 destinations. After a lot of experimentation, including rebooting (did not help), I found this: archive.ubuntu.com: 2001:67c:1360:8001::17 "ping6 vrf internet 2001:67c:1360:8001::17" from the router shell works. ping6/traceroute from a customer connection has the packet dropped by the router. Traceroute gets nothing back at all. 2001:67c:1360:7fff:: is ok. Does not reply to ping because I just made up that address. But I get a valid traceroute all the way to the destination. Anything between 2001:67c:1360:8000:: and 2001:67c:1360:ffff:ffff:ffff:ffff:ffff is dropped. My route table looks like this: albertslund-edge1#show ipv6 forwarding route vrf internet 2001:67c:1360:8001::17 IPv6 Routing Table: Headers: Dest: Destination, Gw: Gateway, Pri: Priority; Codes : K: kernel, I1: isis-l1, SFN: sf-nat64, R: ripng, AF: aftr, B: bgp, D: direct, I2: isis-l2, SLN: sl-nat64, O: ospfv3, D6: dhcp, P: ppp, S: static, N: nd, V: vrrp, A: address, M: multicast, UI: user-ipaddr, GW-FWD: PS-BUSI,GW-UE: PS-USER,LDP-A: LDP-AREA, UN: user-network, US: user-special; Dest Owner Metric Interface Pri Gw 2001:67c:1360::/48 B 0 xgei-0/0/0/6 200 ::ffff:185.24.168.254 ::/0 B 0 xgei-0/0/0/6 200 ::ffff:185.24.168.254 Notice how this is a /48 route and one bit at the /49 level changes how it is routed. That is not right. I tried adding a /128 static route but that does not do anything. The packet is still dropped. I just now discovered this: google.com: 2a00:1450:400e:807::200e That address works fine. But then I changed that one bit in the address: 2a00:1450:400e:8807::200e and voila, the router drops the packet. Now I am stumbled. What could the 49th bit in the destination IPv6 address field in a packet mean to the router, that would make it drop the packet? Some extra information about the network: We are using MPLS with l3vpn (vrf) and l2vpn (vpls). The traffic is qinq tagged before being transported in a l2vpn towards the router in question. The l2vpn does not transport the outer vlan tag. The l2vpn is then terminated on a loopback cable. On the other end of that loopback cable we receive the traffic as ordinary qinq tagged without MPLS tagging. It is on this interface the router apparently drops the packet. It might conceivably also drop the packet on the way out of the l2vpn. I have a similar setup, but instead of a loopback cable, the l2vpn is terminated on another MPLS switch, which then connects to a router of the same model. This setup does not have the problem. The change I introduced was changing from an internal interface called "bvi" to the loopback cable. The bvi interface is a simulated loopback cable construct. We are dropping the bvi interface because it is very buggy. We did not have this problem with the bvi interface however. The hardware is ZTE M6000-S V3.00.20(3.40.1). Thanks, Baldur

It is not my impression that maintaining an updatable database of (AS, prefix) pairs is particularly difficult. What's hard is figuring out who's allowed to put what into the database, and blockchains offer no help at all there.

DSL CPE
by Mike Hammett 24 Jan '18

24 Jan '18

After a few off-list responses (and a couple on) encouraging me to use NANOG, here we go... I've recently walked in to a voice\DSL CLEC that has basically been left to entropy for the last ten years. A lot of the core systems just work, but a lot of things aren't exactly managed the best. They run a Calix\Occam ADSL2+\VDSL infrastructure. For those of you doing DSL, what CPE are you using? I'm looking at one that's just a basic modem where I have a more sophisticated router (or ATA\voice gateway) behind it and then one more generic for residential settings with WiFi and all that jazz. We're kinda debating whether we go just dumb Wi-Fi or something more advanced\powerful. I've heard a lot of good about the Calix GigaFamily in that regard. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest-IX http://www.midwest-ix.com

Call for presentations RIPE 76
by Benno Overeinder 23 Jan '18

23 Jan '18

Dear colleagues, Please find the CFP for RIPE 76 below or at: https://ripe76.ripe.net/submit-topic/cfp/. The deadline for submissions is *11 March 2018*. Please also note that speakers do not receive any extra reduction or funding towards the meeting fee at the RIPE Meetings, see the "Speakers" paragraph in CFP for more information. Kind regards, Benno Overeinder RIPE PC Chair https://ripe76.ripe.net/ripe-pc/ -------------------->>><<<-------------------- Call for Presentations A RIPE Meeting is an open event where Internet Service Providers, network operators and other interested parties get together. Although the meeting is mostly technical, it is also a chance for people to meet and network with others in their field. RIPE 76 will take place from 14-18 May in Marseille, France. The RIPE Programme Committee (PC) is now seeking content proposals from the RIPE community for the plenary sessions, BoFs (Birds of a Feather sessions), panels, workshops, tutorials and lightning talks at RIPE 76. See the full descriptions of the different presentation formats, https://ripe76.ripe.net/submit-topic/presentation-formats/. Proposals for plenary sessions, BoFs, panels, workshops and tutorials must be submitted for full consideration no later than *11 March 2018*. Proposals submitted after this date will be considered depending on the remaining available space in the programme. The PC is looking for presentations covering topics of network engineering and operations, including but not limited to: - IPv6 deployment - Managing IPv4 scarcity - Data centre technologies - Network and DNS operations - Internet governance and regulatory practices - Network and routing security - Content delivery - Internet peering and mobile data exchange - Connected Things (aka. Internet of Things - IoT) Speakers Presenters, RIPE Working Group Chairs and the RIPE Programme Committee are required to cover their own costs to attend a RIPE Meeting (meeting ticket, travel and accommodation). We have various ticket options available depending on your needs. In extraordinary circumstances, the RIPE Chair can waive the meeting fee for presenters. These requests are dealt with on a case-by-case basis via pc(a)ripe.net. Also note that, on an individual basis, participants can apply for a RIPE Fellowship to develop their professional or academic career. For more information, please visit: https://www.ripe.net/participate/ripe/ripe-fellowship Submissions Presenters should be clear on whether they wish to submit a presentation for a plenary or working group (WG) session. At present, most working groups will solicit policy proposals, discussion points or other content directly via their mailing lists. If you’re not sure what kind of session you should be presenting at, please visit: https://ripe76.ripe.net/plenary-or-wg/ RIPE Meeting attendees are quite sensitive to keeping presentations non-commercial, and product marketing talks are strongly discouraged. Repeated audience feedback shows that the most successful talks focus on operational experience, research results, or case studies. For example, presenters wishing to describe a commercial solution should focus on the underlying technology and not attempt a product demonstration. Presenters should indicate how much time they will require. In general, the time allocated for the different presentation formats is as follows: - Plenary presentations: 20-25 minutes presentation with 5-10 minutes discussion - Tutorials: up to two hours (Monday morning) - Workshops: one hour (during evening sessions) to two hours (Monday morning) - BoFs: approximately one hour (during evening sessions) - Lightning talks: 10 minutes total for both presentation and any discussion The following general requirements apply: - Proposals must be submitted using the meeting submission system, https://ripe76.ripe.net/submit-topic/ - Lightning talks should also be submitted using the meeting submission system (https://ripe76.ripe.net/submit-topic/) and can be submitted any time up to and including the meeting week. The allocation of lightning talks will be announced on short notice, in some cases on the same day but often one day prior to the time slot allocated. - Presenters who propose a panel or BoF are encouraged to include speakers from several (perhaps even competing) companies and/or a neutral facilitator. - All presentation proposals will only be considered by the PC if they contain at least draft presentation slides (slides may be updated later on). For panels, proposals must contain a clear description, as well as the names of invited panellists, presenters and moderators. If you have any questions or requests concerning content submissions, please email pc(a)ripe.net. -- Benno J. Overeinder NLnet Labs https://www.nlnetlabs.nl/

End of 2017 hurricane season
by Sean Donelan 23 Jan '18

23 Jan '18

November 30 is the official end of hurricane season in North America. Puerto Rico's Internet routing announcements are 95% of pre-Maria levels. US Virgin Islands Internet routing announcements are 80% of pre-Maria levels. The #(provider name)sucks tweets on twitter in South Florida and South Texas have essentially stopped. I assume this means that providers have repaired almost all Hurricane Harvey and Hurricane Irma damage.
