BCP38 For BGP Customers
by Charles Rumford 22 Nov '22

22 Nov '22

Hello - I'm are currently working on getting BCP38 filtering in place for our BGP customers. My current plan is to use the Juniper uRPF feature to filter out spoofed traffic based on the routing table. The mentality would be: "If you don't send us the prefix, then we don't accept the traffic". This has raised some issues amongst our network engineers regarding multi-homed customers. One of the issues raised was if a multi-homed BGP customer revoked a prefix from one of their peerings, but continued sending us traffic on the link then we would drop the traffic. I would like to hear what others are doing for BCP38 deployments for BGP customers. Are you taking the stance of "if you don't send us the prefix, then we don't accept the traffic"? Are you putting in some kind of fall back filter in based on something like IRR data? Thanks! -- Charles Rumford (he/his/him) Network Engineer | Deft 1-312-268-9342 | charlesr(a)deft.com deft.com

SPF (and other email security protocols) Survey
by Taejoong (tijay) Chung 21 Nov '22

21 Nov '22

Greetings, The Sender Policy Framework (SPF) is an easy way to check whether the sender is authorized to send emails – however, it may cause some security holes if it causes too many DNS lookups. Together with researchers from Virginia Tech and Max-Planck-Institut für Informatik, we would like to understand which challenges operators face when configuring the proper limit of DNS queries for SPF lookups and when deploying other email security protocols. Filling out the survey should take between 5 and 10 minutes; we would highly appreciate your participation. https://www.surveymonkey.com/r/D9M3ZHV Please note that we do NOT collect any personal information, thus the Institutional Review Board (IRB) at Virginia Tech determined the survey as Non-Human Subjects Research. We will aggregate and anonymize all responses during evaluation and share the results after evaluation. Please do not hesitate to drop me a mail if you have questions or comments. Also, please excuse us if you have received this email from different mailing lists. Thank you. Taejoong "Tijay" Chung, Assistant Professor Virginia Tech | Computer Science Knowledge Works II, RM 2228 2202 Kraft Drive, Blacksburg, VA 24060 (540) 231-0667| tijay(a)vt.edu

Random shower thought: GBIC with LC connector...
by Warren Kumari 19 Nov '22

19 Nov '22

Hi there all, While looking through my big box of random optics I suddenly realized that I'd never seen a GBIC with an LC connector, and I started wondering if anyone else had / if such a thing actually exists. Yes, I realize that this would be a fairly niche device - if you arrived somewhere with a device that took GBICs and there was existing fiber with LC connectors you could just replace the patch cable or use an LC-SC convertor, but that doesn't really satisfy my curiosity. A quick look through the GBIC MSA / SFF documentation implies that such a thing *could* probably exist (there is a defined value for the 'LC' connector), but I wasn't able to actually find any. It might not actually be compliant with the specs (the document I found only lists SC fiber or copper (coax with BNC, TNC or DB-9?!)), but that doesn't mean that no-one made them. So, has anyone seen a regular (30mm/1.2") GBIC with LC connectors? And, if so, "pics or it didn't happen"... :-) Obviously I don't have an actual use for this, it's just to satisfy my (OCD) curiosity... W

Fred Brooks has died

18 Nov '22

His Mythical Man Month is a must read for anybody even remotely adjacent to coding, and frankly it should be read out of that context too. RIP Fred and thank you, that was one of the most important books I've ever read. Mike

please update IP addressses for NLNOG Looking Glass BGP sessions
by Teun Vink 18 Nov '22

18 Nov '22

Hi, Here’s a friendly reminder that the IP addresses of the NLNOG Looking Glass BGP daemon has changed a few months ago. All sessions with the old addresses are currently offline. So if you’re peering with the NLNOG Looking Glass, please make sure you’re using the correct addresses: Here are the correct details: IPv4: 212.114.120.72 IPv6: 2001:7b8:62b:1:0:d4ff:fe72:7848 AS: 199036 (unchanged) You can check the state of your BGP sessions at https://lg.ring.nlnog.net/summary. Feel free to contact the NLNOG RING Admins (ring-admins(a)nlnog.net, or give shout in #ring on IRCNet) if you have problems renumbering your side. Thanks! Teun

EVPN ESI BUM Forwarding
by Crist Clark 18 Nov '22

18 Nov '22

My google-fu and attempts to dig through all of the standards is failing me. I am trying to understand the mechanism to prevent an ESI designated forwarder from looping BUM traffic. The scenario I am imagining is BUM traffic coming into the fabric on an ESI link on a non-designated member of the ESI. It still needs to replicate the traffic to all of the VTEPs in the instance, including the other ESI members. Other non-designated members obviously don’t send the BUM traffic out the associated ESI ports, but how does the designated one know not to? It could lookup the source Ethernet address, but MACs move and if it’s new, there’s a race with the BGP NLRI getting there and getting processed before the encapsulated traffic. We’ve been seeing what looks exactly like this not working. A switch with a port channel to two leaf switches complains MAC addresses flapping between where they really are and the port channel. Doesn’t seem like some endpoint out in the fabric doing it because it’s across a whole bunch of VLANs, and it goes away if we shut down one of the port channel links, leaving only one up. I want to understand how this should be working to maybe understand what’s not working here and how to fix it.

FCC Requires Broadband Providers to Display Labels to Help Consumers
by Sean Donelan 17 Nov '22

17 Nov '22

The effective date will be determined later, after publication in the Federal Register and OMB review under PRA. November 17, 2022—The Federal Communications Commission today unveiled new rules that will for the first time require broadband providers to display easy-tounderstand labels to allow consumers to comparison shop for broadband services. The Report and Order approved by the Commission creates rules that require broadband providers to display, at the point of sale, labels that show key information consumers want−prices, speeds,fees, data allowances, and other critical information. The labels resemble the well-known nutrition labels that appear on food products. https://www.fcc.gov/document/fcc-requires-broadband-providers-display-label…
