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.

DHCPv6-PD -> Lack of route injection in RFC
by Steve Teusch 25 Sep '17

25 Sep '17

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?

Settle Free Peering - Default Route Abuse Monitoring
by Raymond Beaudoin 24 Sep '17

24 Sep '17

Hello, Everyone! Many SFP agreements include terms that the peering link will not be used as an upstream with static defaults. A few examples are provided below. *h. must agree not to abuse the peering relationship by engaging in activities such as but not limited to: pointing a default route at the other or otherwise forwarding traffic for destinations not explicitly advertised, resetting next-hop, selling or giving next-hop to others;* Source: http://www.level3.com/en/legal/ip-traffic-exchange-policy/ *2.6. Neither Network shall point default into or transit the other Network where that network has* *not advertised a route for the destination in question.* Source: http://www.zayo.com/wp-content/uploads/2017/02/ZayoPeeringPolicy.pdf How is this monitored and tracked? Are ACLs applied to help enforce this (seems to be limited at scale)? Flow export and alarming? Analytics and anomalous behavior detection? Common professional courtesy? Thanks so much for any insight you may have. I'd like to ensure I'm following all best practices when in IX and peer situations. -Raymond Beaudoin

Application Layer Gateways
by Colton Conor 23 Sep '17

23 Sep '17

Working with an ISP, we recently deployed Comtrend VDSL routers, and Alcatel-Lucent GPON ONTs. Both of these devices uses chipsets made by Broadcom, and as such probably use the same underlying Broadcom operating system if I had to guess. They are different chipsets though as one is from VDSL2, and the other for GPON By default, the Comtrend had the following Firewall -- ALG/Pass-Throughs enabled: FTP H323 IPSec IRC PPTP RTSP SIP TFTP On the Acatel-Lucent (Nokia) ONT, the following came enabled by default from the factory: FTP H323 IPSEC L2TP PPTP RTSP SIP TFTP The only difference between these two is the Comtrend has an IRC as a ALG, and Acatel has L2TP as a protocol type. The other seven ALG protocols as the same. My question is in general, is it a good idea to disable all Application Layer Gateways? The only ALG I have had experience with was a SIP ALG. Almost all SIP providers strongly recommend you disable SIP ALGs as it does more harm and breaks more things than it does good, so we always disable SIP ALG. But what about the other protocols on these two? Do you think they should be enabled or disabled by default? I am leaning towards disabling them all for our standard config.
