Has anyone here worked with DiviNetworks (https://divinetworks.com/) to "sell" their unused bandwidth? I'd be curious to hear any thoughts or experiences.

new tool: rpki-ov-checker
by Job Snijders 06 Feb '20

06 Feb '20

Dear ops, I wrote a simple tool to figure out what kind of invalid a rpki invalid is, this can aid people in understanding the impact of "invalid == reject" routing policies. Only "invalid_unreachable" routes present an operational issue in my opinion, IP addresses covered by "notfound" or "valid" less specific routes will still be reachable. You pass it a file name (or via stdin) with one prefix and origin ASN per line (white space separated) representing your full BGP RIB, and then you can grep specific for the task at hand to extract the info you need: $ rpki-ov-checker full_rib | fgrep -f customer_prefixes | grep invalid | sort -R | head invalid_covered_by_not-found 123.101.0.0/21 4809 covering route: 123.101.0.0/16 4134 invalid_covered_by_valid 46.3.74.0/24 134121 covering route: 46.3.0.0/16 207636 invalid_unreachable 83.231.209.0/24 3949 invalid_unreachable 124.30.247.0/24 9583 invalid_covered_by_valid 125.21.232.0/24 9730 covering route: 125.21.0.0/16 9498 invalid_unreachable 120.29.92.0/24 17639 invalid_unreachable 31.40.164.0/24 200872 invalid_covered_by_notfound 45.12.139.0/24 40676 covering route: 45.12.136.0/22 35913 invalid_covered_by_valid 122.160.178.0/24 24560 covering route: 122.160.0.0/16 24560 invalid_covered_by_valid 61.90.251.0/24 21734 covering route: 61.90.192.0/18 7470 NTT is using this to figure out who we need to help fix their ROA or correct their BGP announcements.

Disney+ Geolocation issues
by Michael Crapse 06 Feb '20

06 Feb '20

Myself and a few other ISPs are having our eyeballs complain about disney+ saying that they're on a VPN. Does anyone have any idea, or who to contact regarding this issue? This is most likely improper geolocation databases. Anyone have an idea who they use? Mike

We (discourse.org) have reports from multiple customers that their users are unable to negotiate SSL with our sites when using their AT&T Wireless data connection. The problem is be affecting users around Chicago and Pennsylvania. Evidence points to some sort of SSL interference/tampering. Cheers, Michael Brown

Help with survey on enterprise network challenges?
by Joseph Severini 04 Feb '20

04 Feb '20

Hi, My name is Joseph Severini, and I am a PhD student in the Computer Science Department at Carnegie Mellon University. I’m working on a research project to identify common operational challenges in modern enterprise computer networks. I’ve put together a survey to identify these challenges by analyzing some operational problems found in the Network Engineering Stack Exchange open-source dataset. You’ll be given a problem from the dataset and asked some questions about it. I would appreciate it if you would consider taking this survey, which can be found at the link below: http://cmu.ca1.qualtrics.com/jfe/form/SV_dm6i9znuPWlLDN3 The survey should take ~15 minutes. Participation is voluntary, with no compensation, and all responses are anonymous. You must be at least 18 years old to complete the survey. Thanks, Joseph Severini PhD Student CMU Computer Science Department

EVPN multicast route (multi home case ) implementation / deployment information
by Mankamana Mishra (mankamis) 04 Feb '20

04 Feb '20

Folks Wondering if there is any known implementation of EVPN multihome multicast routes which are defined in https://tools.ietf.org/html/draft-ietf-bess-evpn-igmp-mld-proxy-04 there is some change planned in NLRI , we want to make sure to have solution which does work well with existing implementation. Note: Discussion involves Nokia, Juniper, Cisco, Arista already. So looking for any other vendor who have implementation. Mankamana
