Two guys have authority over different parts of a network. They don't agree and neither budges. The manager is not technical (at all) and is hands off on decisions like those. I see fights like this in configs all the time. You look at the configs and go WTF, but after learning what happened in the past between those two folks I go; "Ok, NOW I get it." And for 'clearly defined'...well...to put it politely 'clearly defined' is subjective. ;) I'm OCD about KISS, documentation and consistency, but many folks are not. They want it their way, regardless of what is already there, and they like to turn knobs and not let others know what knobs they turned. You wouldn't believe what we see out here on the raggedy edges of the internet. I started my career in the 90s with a company called Digital Island. There were extremely competent folks building it. Every thing was KISS and consistent. It was a beautiful DFZ network. I miss that. 2001 was the last time I saw it. Been on the ragged edge ever since. scott

BGP prefix filter list
by Baldur Norddahl 30 May '19

30 May '19

Hello This morning we apparently had a problem with our routers not handling the full table. So I am looking into culling the least useful prefixes from our tables. I can hardly be the first one to take on that kind of project, and I am wondering if there is a ready made prefix list or similar? Or maybe we have a list of worst offenders? I am looking for ASN that announces a lot of unnecessary /24 prefixes and which happens to be far away from us? I would filter those to something like /20 and then just have a default route to catch all. Thanks, Baldur

VPN / IPSEC Management
by Chris Knipe 30 May '19

30 May '19

Hi Guys, Quick question... In orgs using frequent and large amounts of IPSec, what are you guys using in terms of configuration management / documentation? Especially in terms of Phase 2 and documenting what the relevant Phase 2s are for? Is it a matter of text files / spreadsheets, or are there something out there to manage this with? -- Regards, Chris Knipe

Internet emergency alerts: Alexa now supports "Announcements"
by Sean Donelan 29 May '19

29 May '19

Amazon has announced a new API for its voice services, i.e. Alexa. This enables one-way Alexa announcements within a household and from Apps without prompting by the user. Although the Amazon blog did not comment about the use of Amazon Announcements concerning Emergency Alert System broadcasts (e.g. tornado warnings, evacuation alerts, wildfires, etc), this newe API may solve the previous constrain that Alexa devices only responded to user interaction. Previously, Alexa speakers could tell you there was a tornado warning when you asked for the current weather or passively show weather warnings on Amazon Echo Show screens. Alexa would not proactively announce warnings until you prompted it. I don't know if Amazon will leave it up to 3rd parties to create Apps with emergency alert announcements. https://developer.amazon.com/blogs/alexa/post/c291e779-366b-4e7f-93e2-782b2… Google Search passively shows some emergency alerts at the top of its search pages based on your location. Google Assistant devices do not appear to react to emergency alerts. Netflix, Hulu and other streaming apps are likely the wrong layer for emergency alerts. Alerts should likely be part of the device management layer, to provide consistent behavior across apps instead of app by app.
