Why the internal network delays, Gmail?
by Nate Metheny 21 Jun '17

21 Jun '17

Help (and hi)! I work in higher education and we've been experiencing problems with Google delaying or queuing email for delivery to our domain. Here's some truncated email headers: ** Example 1: X-Received: by 10.237.55.65 with SMTP id i59mr10986018qtb.62.1472137448952; Thu, 25 Aug 2016 08:04:08 -0700 (PDT) Received: by mail-qt0-f175.google.com with SMTP id u25so27419242qtb.1 for <@***>; Thu, 25 Aug 2016 12:05:46 -0700 (PDT) ** Example 2: X-Received: by 10.36.1.75 with SMTP id 72mr5275579itk.40.1472130531887; Thu, 25 Aug 2016 06:08:51 -0700 (PDT) Received: by mail-it0-f48.google.com with SMTP id x131so289116132ite.0 for <@***>; Thu, 25 Aug 2016 11:50:42 -0700 (PDT) In both of these examples, these emails haven't even left Google's internal network yet; I'm getting blamed for these delays, however there is no delay in receiving these emails after they leave Google's network. Are other people having this same problem? I've tested delivery to my network from many outside sources and all SMTP requests go through without delay; this issue seems be exclusive to Google-hosted and Gmail accounts and domains. -- Nate <natemetheny(a)gmail.com>nate(a)dopedesign.com

Internet connectivity in Ghana
by Rishi Singh 04 Jun '17

04 Jun '17

Has anyone dealt with getting internet connectivity in Ghana? I've been doing a lot of research and saw some peering plans with Nigeria but nothing solid there yet. Currently a financial client of mine is paying quite a bit every quarter on satellite up link fees. Do any of the major carriers have any direct connectivity into Ghana? Thank you,

RFC2544 Testing Equipment
by Nick Olsen 02 Jun '17

02 Jun '17

Greetings all, Looking for a good test set. Primary use will be testing L2 circuits (It'll technically be VPLS, But the test set will just see L2). Being able to test routed L3 would also be useful. Most of the sets I've seen are two sided, A "reflector" at the remote side, And the test set in hand run by the technician. Looking to test up to 1Gb/s at various packet sizes, Measure Packet loss, Jitter..etc. Primarily Copper, But if it had some form of optical port, I wouldn't complain. Outputting a report that we can provide to the customer would be useful, But isn't mandatory. Doesn't need anything fancy, Like MPLS awareness, VLAN ID's..etc. Nick Olsen Sr. Network Engineer Florida High Speed Internet (321) 205-1100 x106

Leasing /22 blocks

Recently had someone offer to lease some IPv4 address space from me. Have never done that before. I thought I would ask the group what a reasonable monthly rate for a /22 in the United States might be. Thanks in advance! Ed(ward) Ray

Anyone using Arista 7280R as edge router?
by David Hubbard 01 Jun '17

01 Jun '17

Hey all, have some Brocade MLXe’s that can no longer handle a full v4 and v6 route table while also having VRF support (dumb CAM profile limitations in the software). Mine don’t do anything fancy; just BGP to a few upstream peers and OSPF/OSPFv3 to the inside, management VRF, some ACL’s. I’m looking at the ASR9001 with add-on ports since I need (10) 10gig. However, I’ve also been running some Arista 7280SE’s for the past 18 months with no issues, and they want me to consider their 7280R since it would give me more ports, in addition to some higher speed ports, which would be nice if I ever want to upgrade some of our peering to 40 or 100gig. Arista’s specs say the 7500R / 7280R can handle 1M ipv4+ipv6 routes in hardware (FIB): https://www.arista.com/assets/data/pdf/Whitepapers/FlexRoute-WP.pdf In theory, it would last at least a few years if the v4 table doesn’t get too crazy between now and then. Curious if anyone has deployed a 7500R or 7280R in this role and what the feedback has been? The 9001’s 4M ‘credits’ for the combo of v4 +(2)v6 routes obviously goes much further, but I think either one would make it to their expected end of life, or if not on the Arista side, I’d probably have spent half as much. Thanks, David

NCCoE Secure Inter-Domain Routing Project - request for industry input.
by Montgomery, Douglas (Fed) 31 May '17

31 May '17

The National Cybersecurity Center of Excellence (NCCoE) requests community input on a proposed project entitled: Secure Inter-Domain Routing, Part 1: Route-Hijacks. https://nccoe.nist.gov/projects/building-blocks/secure-inter-domain-routing The objective of the project is to examine and demonstrate the state of the RPKI and BGP Origin Validation technologies in realistic scenarios and to address identified concerns with their deployment and use (e.g., security, robustness, management / monitoring, multi-vendor inter-operation). This request is for industry input on the the proposed project plan. In particular we seek input from both network operators and enterprises on practical issues and barriers to adoption and suggestions for how these could be addressed in the project. Please see the link above for instructions for submitting comments and how you can join a community of interest for the project. *The intention is not to have the discussion here on the NANOG list.* Thanks dougm — Doug Montgomery, Mgr Internet & Scalable Systems Research at NIST/ITL/ANTD

BCP38/84 and DDoS ACLs
by Graham Johnston 29 May '17

29 May '17

I really did try looking before I sent the email but couldn't quickly find what I was looking for. I am looking for information regarding standard ACLs that operators may be using at the internet edge of their network, on peering and transit connections, wherein you are filtering ingress packets such as those sourced from UDP port 19 for instance. I've found incomplete conceptual discussions about it nothing that seemed concrete or complete. This doesn't seem quite like it is BCP38 and more like this is BCP84, but it only talks about use of ACLs in section 2.1 without providing any examples. Given that it is also 13 years old I thought there might be fresher information out there. Thanks, graham

Cisco NCS5501 as a P Router
by Erik Sundberg 28 May '17

28 May '17

We're at the growing point where we need a dedicated P router for a core device. We are taking a serious look at the NCS5501. Is there anyone else using a NCS5501 as P Router or just general feedback on the NCS5501 if you are using it? The big downside is it's only has a single processor I Can't justify a ASR9K or NCS5500 Chassis yet. ________________________________ CONFIDENTIALITY NOTICE: This e-mail transmission, and any documents, files or previous e-mail messages attached to it may contain confidential information that is legally privileged.
