Information about the national test of the Emergency Alert System
by Sean Donelan 28 Sep '17

28 Sep '17

> And your upstream(s) to work. And their upstream(s) to work. etc. If 90% > of the stations in the EAS web are down you may end up with nothing > working. 6% of TV stations are operating in Puerto Rico 15% of radio stations are operating in Puerto Rico Nationally, there are about 28,000 cable systems, radio and television stations. This test will not use the FEMA primary entry point system, so its only a partial test of the national EAS. Today's national test of the Emergency Alert System will be the same as the 2016 national test. It is a partial test of the EAS, using the FEMA IPAWS system over the internet (i.e. Akamai and Cloudfront are used as CDNs) to the distribute the emergency test message. Cable, radio and TV stations need a working Internet connection as well as radio receivers and transmitters for IPAWS and EAS. Although the national test was scheduled back in July, its still a good test opportunity to see how the internet and EAS works in Puerto Rico and the U.S. VI with so much damage to the infrastructure. The one minute national test should not intefere with disaster recovery efforts in PR or USVI.

Google DNS64 misconfigured?
by Joel Whitehouse 28 Sep '17

28 Sep '17

I had an ipv6-only lab environment cease being able to browse much of the internet on Monday. Tracked the issue down to google's public DNS64 service; the following queries should return DNS64 responses from the 64:9bff::/96 prefix, however, I'm getting 0 DNS64 answers from dig on both their servers for the last 60 hours: dig @2001:4860:4860::64 ipv4only.arpa AAAA dig @2001:4860:4860::6464 ipv4only.arpa AAAA DNS works fine, just not DNS64. A forum topic [0] suggests this behavior might be intermittent but no official response from google there. Is google's public DNS64 down for anyone else?

Re: DHCPv6-PD -> Lack of route injection in RFC
by Baldur Norddahl 27 Sep '17

27 Sep '17

This method is lacking because you might have several routers eg. using VRRP and the backup router will not learn anything from a relay on the primary. Den 22. sep. 2017 14.02 skrev "Steve Teusch" <steve.teusch(a)rtr.guru>: I am running into venders that do not support injection of a delegated route when operating as a DHCPv6 relay (or server for that matter). Brocade supports this, but I am not finding this as part of any of the RFC's. This is to deliver home ISP service, so it is very important or return packets won't go to the client unless the route is manually added as a routing protocol is not an option. There should be a MUST activity for this somewhere. Anyone know what gives?

Major European Continental Long Haul Conduit
by Rod Beck 26 Sep '17

26 Sep '17

I would to tap the collective wisdom of NANOG. What are the major conduit systems in Europe? I know when MFN Europe went bankrupt, everybody jumped in and bought their fiber. So I list GTT/Hibernia, EUNetworks, Zayo, and who else rids this conduit system. And who rides the Level3 conduit and what the other key systems. And yes, I am thinking of the terrestrial routes connecting the European racetrack: Amsterdam, Frankfurt, Paris, and Milan. Regards, Roderick.

IPv6 migration steps for mid-scale isp
by Fredrik Sallinen 26 Sep '17

26 Sep '17

Hello, Recently we have decided to start IPv6 migration in our network. We have ~1K BNGs and connecting our customers to network using PPPoE. I'd be interested in hearing from the technical community about their experiences and recommendations on this process. I'm wondering: Shall I go for IPv6-only deployment or dual stack? Where to start with IPv6? (core, edge or ...) What are the best practices for ISPs? What are the costs and return on investment? How to identify address CPE and legacy application issues? Fredrik

Nanog attendees are invited to Friday Lunch at the Internet Archive (in,San Francisco) and a tour...
by mark seiden 26 Sep '17

26 Sep '17

You've probably used the Wayback Machine, but have you ever wondered how it works? We think of Nanog folks as part of our natural community. So Nanog attendees who will be in the Bay Area before or after the upcoming San Jose Nanog meeting are particularly welcome to be our guests at community lunch at the Internet Archive (300 Funston at Clement, San Francisco) on either Friday Sept 29, or Friday Oct 6. Lunch, buffet style, starts promptly at noon, and prepare to say what you're up to, because we go around the room making brief self-introductions. Afterwards, you can tour the Archive -- see what we do and possibly get involved in helping out with some ambitious plans. To come on Sept 29, RSVP by tomorrow (Sept 27) with a count (so we have enough food) to jcg(a)archive.org or to come on Oct 6, RSVP by Wednesday (Oct 4) with a count to jonah(a)archive.org (who will also be at the conference). (There is often street parking for at least 2 hours. Public transportation involves the 38L bus -- we're at the other end of town from Bart/Caltrain, very close to the Presidio and the Golden Gate Bridge.) If you are local to the Bay Area or hanging around after Nanog, you may want to attend our upcoming Annual Celebration on the evening of Oct 11: https://blog.archive.org/2017/08/30/the-internet-archives-annual-bash-come-… More information about the Internet Archive at https://archive.org

Regex expression
by craig washington 25 Sep '17

25 Sep '17

Hello all, not sure if this is the right place for this. I am not the best with Regex and was looking for an expression in a Juniper that will match on only so many numbers. Meaning, I am looking at the mpls lsp statistics "show mpls lsp transit statistics" and I only want to see the LSP's that have larger Bytes, for instance I only want to see stuff that has at least 12 digits or longer. Any help would be greatly appreciated, and if this is the wrong thing to ask here, I have no qualms with that either 😊 Thanks again.
