plea for comcast/sprint handoff debug help
by Randy Bush 11 Nov '20

11 Nov '20

tl;dr: comcast: does your 50.242.151.5 westin router receive the announcement of 147.28.0.0/20 from sprint's westin router 144.232.9.61? details: 3130 in the westin announces 147.28.0.0/19 and 147.28.0.0/20 to sprint, ntt, and the six and we want to remove the /19 when we stop announcing the /19, a traceroute to comcast through sprint dies at the handoff from sprint to comcast. r0.sea#traceroute 73.47.196.134 source 147.28.7.1 Type escape sequence to abort.

Bad next-hop? not propagated? covid? magic? which is why we wonder what comcast (50.242.151.5) hears from sprint at that handoff note that, at the minute, both the /19 and the /20 are being announced, as we want things to work. so you will not be able to reproduce. so, comcast, are you receiving the announcement of the /20 from sprint? with a good next-hop? randy

Strange connectivity issue Frontier EVPL
by Jay Hennigan 11 Nov '20

11 Nov '20

We have a strange issue that defies logic. We have a NNI at our POP with Frontier serving as an aggregation circuit with different customers on different VLANs. It's working well to several customers. Bringing up a new customer shows roughly half of the IP addresses unreachable across the link, as if there's some kind of load-balancing or hashing function that's mis-directing half of the traffic. It's consistent, if an address is reachable it's always reachable. If it's not reachable, it's never reachable. Everything ARPs fine. The Frontier circuit is layer 2 so shouldn't care about IP addresses. Frontier tech shows no trouble. They changed the RAD device on-premise. We've triple-checked configurations, torn down and rebuilt subinterface, etc. with no joy. Any suggestions? -- Jay Hennigan - jay(a)west.net Network Engineering - CCIE #7880 503 897-8550 - WB6RDV

Technology risk without safeguards
by Suresh Kalkunte 11 Nov '20

11 Nov '20

Hello, I believe the below described method of causing intentional (1) damage to equipment in data centers and (2) physical injury to a person at the workplace is on-topic for the NANOG community, if not, I look forward to your feedback. As a software developer who has subscribed to the NANOG mailing list for a number of years, I post this note relying on intellectual honesty that I have had the opportunity to observe since 1996-97. The below described technology risk is applicable to computing/communication equipment rendered vulnerable by Intentional Electromagnetic Interference (jamming an electronic device) and the risk of health sabotage affecting people (jamming a human) managing the Internet infrastructure enabled by intentional application of powerful radiofrequency fields (RF) emitted by re-purposed components salvaged from a kitchen heating appliance (Magnetron) or from an outdoor high gain/power Line of sight transceiver (unidirectional microwave radio) which has a harm causing range up to 25 meters (estimated using a Spectral Power Density calculator like www.hintlink.com/power_density.htm) This risk from mis-application of powerful RF is from human operated or IoT apparatus** with an avenue of approch from (a) subterrain placement aided by a compact/mini directional horizontal drilling machine (eg. principle of placing a stent in the heart) and/or (b) strategic placement in an obscure over-surface location to maximize negative impact on the target of opportunity. With building materials or ground offer insufficient* protection to block the passage of powerful RF and the absence of diagnostic/forensic tests to detect biomarkers expressed post-overexposure to harmful RF (combination of RF frequency, Spectral Power Density/Specific Absorption Rate incident on a person and duration of exposure), intentional damage to electronic equipment and people is at present unrestricted. The purpose of bringing this method of exploting technology to your attention is with an interest to build the momentum for ushering in the much needed safeguards in this context. Thanks.

CNAME records in place of A records
by Dovid Bender 09 Nov '20

09 Nov '20

Hi, Sorry if this is a bit OT. Recently several different vendors (in completely different fields) where they white label for us asked us to remove A records that we have going to them and replace them with CNAME records. Is there anything *going around* in the security aranea that has caused this?

In response to feedback from operational security communities, CAIDA's source address validation measurement project (https://spoofer.caida.org) is automatically generating monthly reports of ASes originating prefixes in BGP for systems from which we received packets with a spoofed source address. We are publishing these reports to network and security operations lists in order to ensure this information reaches operational contacts in these ASes. This report summarises tests conducted within usa, can.

BGP Peers Data modeling schema
by Douglas Fischer 06 Nov '20

06 Nov '20

I'm designing a tool for provisioning configurations for an ITP and his Peers. The idea is that based on that, all the configs to all the involved components configurations to be deployed based on that source of data. I'm Talking about Routers, BMP, SNMP tool(Ex.: Zabbix), etc... But, once again, I'm feeling that I'm reinventing the wheel. I'm pretty sure that someone else has already suffered from that. I search for a bit, and I didn't find anything... But with this gray area between developers and network operators, I'm not sure if I'm looking at the right place. I even tried to look at http://schema.org but didn't find anything related to networks and BGP there yet. So, anyone could point me in the right direction? -- Douglas Fernando Fischer Engº de Controle e Automação

Verizon or Verizon Wireless contact
by Jeff Shultz 05 Nov '20

05 Nov '20

Looking for a contact with a clue at Verizon/Wireless who can help me with a problem, to wit, Verizon is blocking calls from our landline customers to one of their local wireless prefixes. We've got the error that the Verizon switch gives ("Welcome to Verizon your call can not be completed as dialed. Announcement for switch 3 0 dash 2.) Any publicly available numbers or tech support just leads me in circles. I figure if I keep at it long enough, I'll collect the whole set of their toll free numbers... but I'd prefer not to.
