Multihomed route visibility
by Boyle, Patrick 04 Nov '19

04 Nov '19

We are advertising the same prefix to ISP A & ISP B. When looking at various route servers across the world, I always see the path through ISP A in the BGP table, but most don't show a path at all through ISP B (some do, like Oregon IX). I would expect any router with the full table to show both routes. Is this a consequence of how the route servers are peered up? Are they only displaying the preferred path? ISP Issue? Am I missing something? Any help would be appreciated.

D'oH III: In 3-D! Plot Twist from Google/Chrome, Vixie approves?
by Jay R. Ashworth 01 Nov '19

01 Nov '19

It's not clear to me whether Paul is expressing approval of the whole shebang at this point, or just the one change they've made, but, just on first look, I don't think that change addresses *my* distaste for DoH, as discussed in last month's 100-poster. :-) https://www.zdnet.com/article/dns-over-https-google-hits-back-at-misinforma… TL;DR: they (Chrome) won't enable DoH unless it's being run from an internet which they know supports it; there are apparently a list of 8-12 ISPs/etc which are announcing such support.

Best components for a full mvno core network?
by Dario Renaud 01 Nov '19

01 Nov '19

Hello, At my day job, we are considering going Full MVNO. Which means building a mobile core network. I was wondering if some of you would have feedback or advices on the solutions currently available? We would like to avoid the big providers (Ericsson & such). Ideally, something opensource, or, if proprietary, a company maybe willing to license access to the code (one can dream). There seems to be a lot of bits and pieces available out there, with a mix of full, fullish or partial solutions. This makes for quite the puzzle. Among the ones I found most interesting: nextEPC, covering, well, the EPC… (https://github.com/nextepc/nextepc) It looks like the more active open EPC implementation out there. And it seems that Yate people have a commercial product covering basically everything needed ( https://yatebts.com/solutions_and_technology/mobile_virtual_network_operato…) What do you think? Regards Dario Renaud

T-Mobile help!!
by David Funderburk 31 Oct '19

One of our customers office number is coming across as 'Survey Call' on T-Mobile cell phones. I know with certainty it's with 'T-Mobile' phones. I don't have another contact on another network that I know I can try. How do we get that fixed?

RTG
by Drew Weaver 31 Oct '19

31 Oct '19

Hello, We've been using this product for years and years http://rtg.sourceforge.net/ to collect and store SNMP statistics. It has been working fine for us. I haven't really been able to find much information about forks, new versions, and development happening on it. A while back I heard that Yahoo created their own version of it but I could never find it. Does anyone know if there is a spiritual successor to RTG that pretty much works the same way that is modernized? Thanks! -Drew

Looking for input -- OSS tooling
by Leslie Daigle 30 Oct '19

30 Oct '19

I know that a number of people on this list use, and/or contribute to, open source software tools (e.g., *RTG). As I outlined in my lightning talk at the NANOG meeting last June, I’m collecting information about what operators find useful/off-putting in the use, contribution to, and support of open source software tools. My plan, and why I hope this project will be interesting to you, is to share the results of the data collection publicly so that supporters of OSS projects will be able to better tune them to what works for you. People who fund open source are asking for answers, so your thoughts would be appreciated! If you have 8 - 10 minutes to spare and would be willing to contribute your thoughts, you can get to the questionnaires here: https://possie.techark.org/operators-and-open-source-software-survey/ Thing 1 — “Questionnaires” because there’s one for individual contributors, and one for decision makers. You’re welcome to fill out both, if applicable. Thing 2 — the questionnaire does not require you to provide your name or contact info — that’s optional, if you’d like to do some follow up. Thanks for considering contributing your thoughts! Leslie. -- ------------------------------------------------------------------- Leslie Daigle Principal, ThinkingCat Enterprises ldaigle(a)thinkingcat.com -------------------------------------------------------------------

RE: fuzzy subnet aggregation
by Jakob Heitz (jheitz) 30 Oct '19

30 Oct '19

Another thing to consider is how long it takes to download into forwarding hardware. Forwarding hardware is optimized for forwarding, not programming. The programming has to wait for time slots when forwarding is not using the memory. When you do smart aggregation, a single changed route could cause a massive change in your aggregates. Then the resulting download could be both long and cause glitches. Glitches, because you remove some aggregates while adding others within a finite time. During this finite time, you may have incorrect routing. Regards, Jakob.

IXP Renumbering: Equinix Miami (formerly known as NOTA)
by Fredy Künzler 30 Oct '19

30 Oct '19

It seems that many participants of the Equinix Miami Exchange (formerly Nap of the Americas NOTA) are unaware of the required IP renumbering. Init7 AS13030 sees at least 50% of the new BGP sessions still down. While the usefulness of the replacement of the peering mesh /23 with another /23 could be discussed, the process itself hasn't been announced, at least we didn't became aware of it until recently, and only because some peers asked for new sessions. Equinix provided a website with the necessary information, but it seems that they failed to announce it. Interestingly the schedule is already overdue. https://ix.equinix.com/home/ip-migration/mi/ I would propose that some IXP operators should write a BCOP to avoid future renumbering pain. -- Fredy Künzler Init7 (Switzerland) Ltd.
