COM zone operational announcement: DNSSEC algorithm rollover
by Wessels, Duane 28 Nov '23

28 Nov '23

Verisign will soon begin the transition to DNSSEC algorithm 13 (ECDSA) for the COM zone. Over the next few days, algorithm 13 signatures will start to appear in the zone, followed by the algorithm 13 DNSKEY records. We expect the DS record for the COM zone to change from algorithm 8 to algorithm 13 on or around December 7. Additional information can be found at our blog post and DNS-OARC presentation URLs below: https://blog.verisign.com/security/dnssec-algorithm-update/ https://indico.dns-oarc.net/event/47/contributions/1012/ We expect no operational impacts for end users, but please feel free to reach out to us with concerns or any observations of anomalous behavior related to this algorithm rollover.

CPE/NID options
by Ross Tajvar 27 Nov '23

27 Nov '23

I'm evaluating CPEs for one of my clients, a regional ISP. Currently, we're terminating the customer's service (L3) on our upstream equipment and extending it over our own fiber to the customer's premise, where it lands in a Juniper EX2200 or EX2300. At a previous job, I used Accedian's ANTs on the customer prem side. I like the ANT because it has a small footprint with only 2 ports, it's passively cooled, it's very simple to operate, it's controlled centrally, etc. Unfortunately, when I reached out to Accedian, they insisted that the controller (which is required) started at $30k, which is a non-starter for us. I'm not aware of any other products like this. Does anyone have a recommendation for a simple L2* device to deploy to customer premises? Not necessarily the exact same thing, but something similarly-featured would be ideal. *I'm not sure if the ANT is exactly "layer 2", but I don't know what else to call it.

ACX7100 Woes - Operator Outreach -
by Edwin Mallette 27 Nov '23

27 Nov '23

In attempting to operationalize the ACX7100 I have run into quite a few challenges with the platform once I stray outside of traditional routing and switching. The EVPN instances seem to have quite a few caveats and things like CFM and RFC2544 traffic generation. Many of the show commands don't seem to work, many of the counters either don't work or update slowly (like I run the command to show CFM messages and it says it sent 100 then I run it again a couple seconds later and it says 10000 sent then a couple seconds later it says 1000000 sent) this with a periodicity of 1 message per second. Oh and the latest is that our original OEM QSFPs just disappear. As in they not only stop working but the chassis no longer sees them. I guess I'm just reaching out to see if I'm all alone in my struggles... Warm Regards and happy Monday after Thanksgiving, Ed

Generally accepted BGP acceptance criteria?
by Tom Samplonius 27 Nov '23

27 Nov '23

In the world of IRR and RPKI, BGP route acceptance criteria is important to get right. DE-CIX has published a detailed flow chart documenting their acceptance criteria: https://www.de-cix.net/en/locations/frankfurt/route-server-guide But I don’t see a lot of operators publishing their criteria. I imagine there is a some sort of coalescing industry standard out there, but so far I can’t find it. Of the upstreams I use, just one publishes a flowchart. Another is basically refusing to explain anything other than they “use” IRR and RPKI, ad that RPKI is “good”. I assumed that everyone implementing RPKI validation, would skip IRR route object validation if the route is RPKI-valid. I assumed that everyone is doing this now, or would do this when they implement RPKI validation. But I spoke to an operator today, which still expects all routes to pass IRR as well (and while they perform RPKI-validation, they effectively do nothing with the result). To me, this seems like a different direction than most operators are going. Or is it? The most surprising thing in the DE-DIX flow chart, was that they check that the origin AS exists in the IRR as-set, before doing RPKI, and if the set existence fails, they reject the route. I don’t see a problem with this, as maintaining as-sets is easy, but it does prevent an eventual 100% RPKI future with no IRR at all. I also thought there may be an informational RFC on this, but I couldn’t find anything. Has there been anything published or any presentations given, on generally accepted BGP route acceptance criteria? Tom

Advantages and disadvantages of legacy assets
by Eric Dugas 23 Nov '23

23 Nov '23

Greetings! Let's say you inherit legacy assets (ASN & IPv4 netblock), what are the first advantages that come to mind (beside not having to pay annual fees). Any disadvantages? The ones I can think of is the lack of RIR routing security services (in the ARIN region at least). No IRR, no RPKI at all. Eric
