BFD for long haul circuit
by Harivishnu Abhilash 23 Jul '20

23 Jul '20

Classification:Public Guys, I'm looking for recommendation regarding BFD timers that we can use for long haul circuit. RTT is roughly around 110 ms. In fact this is a l2vpn ckt provided by a telco. Can you please advise the factors we can consider when setting the BFD timers (or any recommended values)? I have set 10 ms dead time but this is causing BFD to go down occasionally.

My toolbox in the garage has torque wrenches and allen wrenches and a GS-911 for talking to the Motronic on my bike, too. It's a pretty useful toolbox. I use all of them. I don't keep them all in the same drawer of the toolbox, though. Guessing you don't either. Or if you do, I *probably* don't want you working on my bike. I for one would be happy if someone came up with some different acronyms and subdivide the "world of SDN" into some number of sub-techonologies/practices that were at least a little more cohesive with each other so then at least we'd know what keywords to fit into our news feeds so we could pay better attention to the bits that are more relevant to where we are. Ansible/netmiko/<whatevertoolset>+CI/CD applied to kit (and people) does not resemble OpenDaylight or what hyperscalers are doing with DPDK on cards or the Microsoft FPGA-NIC trickery except in the broadest of views. All are good. Sure, they all belong in the toolbox. But maybe not in the same drawer. As it is, we have marketing people sticking "SDN" onto every bloody thing that comes along in the hopes that it'll better catch the attention of someone without enough of a clue that they'll cough up (and leave someone else to figure out what to do with it). I freely admit that's just what they do and expecting them to do anything different is wishful thinking, but I don't see any of us doing anything about it except creating long email chains wherein we just keep trying to munge apples and oranges together. :) -bacon

ARIN/LACNIC Inter-RIR Transfers Update
by John Curran 22 Jul '20

22 Jul '20

NANOGers – FYI - LACNIC has adopted a policy for inter-RIR transfers of IPv4 number resources, and this policy is compatible with ARIN’s inter-RIR transfer policies. FYI, /John John Curran President and CEO American Registry for Internet Numbers Begin forwarded message: From: ARIN <info(a)arin.net<mailto:info@arin.net>> Subject: [arin-announce] ARIN/LACNIC Inter-RIR Transfers Update Date: 21 July 2020 at 3:52:59 PM EDT To: <arin-announce(a)arin.net<mailto:arin-announce@arin.net>> Inter-RIR transfers of IPv4 addresses can now be processed between ARIN and LACNIC. On 21 July, LACNIC announced that they are now able to process inter-RIR IPv4 transfers. https://www.lacnic.net/4711/2/lacnic/lacnic-starts-processing-inter-rir-tra… Because ARIN and LACNIC have reciprocal policies, this means ARIN can now conduct inter-RIR IPv4 transfers between the two regions.

Issues with deliverability to hotmail -- any Microsoft contacts?
by Brock Tice 22 Jul '20

22 Jul '20

We have been having issues delivering email to hotmail users again, no bulk mail, just various personal emails from a server on our network. We have signed up for SNDS, only identified one mail server of a customer on our network that was flagged as an issue, and it has been remedied, no longer showing in SNDS. We have repeatedly requested removal of our subnet from their block list and it has not worked. MS has done a great job of making it impossible to contact anyone about this. Does anyone have pointers on what else can be done or whom we should contact to get this resolved? Thanks, --Brock -- Brock M.

non-rate limited, automatable Looking Glasses?
by Lars Prehn 19 Jul '20

19 Jul '20

Hi everyone, In the next couple of months, I want to compare data plane and control plane measurements on a larger scale. In particular, I'm looking for (publicly accessible) devices that receive BGP feeds and can perform a bunch of automated (paris) traceroutes. I currently do not have an exact probing rate or target set in mind; however, I'm sure that manually entering IP addresses as targets for usual Looking glasses won't cut it. Does anyone know less-restricted (maybe even automatable?) Looking Glasses (or similar devices) or is willing to provide access to one? BTW: I though about picking Atlas probes from ASes that feed BGP Collector Projects (e.g. RIPE RIS or RouteViews). Unfortunately, the respective probes are often really far apart from the feeding routers; thus, their individual perspectives are likely misaligned :( Best regards, Lars

MX204 Rails
by Nicholas Warren 17 Jul '20

17 Jul '20

We're having a ton of problems trying to find a part number for juniper rails (for an mx204) or even finding something that's compatible. I suppose we can just put the router on a rack mount shelf, but man... it's like pulling teeth to get this part number... Does anyone know of where I can find this part number? (no, our distributer can't find the part number, and communication problems with juniper tac is making them think that we're talking about the rack) nic

CloudFlare Issues?
by Chris Grundemann 17 Jul '20

Looks like there may be something big up (read: down) at CloudFlare, but their status page is not reporting anything yet. Am I crazy? Or just time to give up on the internet for this week? -- @ChrisGrundemann http://chrisgrundemann.com
