Internet Exchanges supporting jumbo frames?
by Kurt Kraut 17 Mar '16

17 Mar '16

Hi, I'm trying to convince my local Internet Exchange location (and it is not small, exceed 1 terabit per second on a daily basis) to adopt jumbo frames. For IPv6 is is hassle free, Path MTU Discovery arranges the max MTU per connection/destination. For IPv4, it requires more planning. For instance, two datacenters tend to exchange relevant traffic because customers with disaster recovery in mind (saving the same content in two different datacenters, two different suppliers). In most cases, these datacenters are quite far from each other, even in different countries. In this context, jumbo frames would allow max speed even the latency is from a tipical international link. Could anyone share with me Internet Exchanges you know that allow jumbo frames (like https://www.gr-ix.gr/specs/ does) and how you notice benefit from it? Best regards, Kurt Kraut

Latency in ATT DSL from Houston.
by Charles van Niman 17 Mar '16

17 Mar '16

Hello All, I am trying to get some assistance with latency I am seeing inside ATT. DSL Support has been next to useless, and I am already pursing different connectivity options, but getting this fixed would be awesome. The problem is two fold, I see latency to pretty much any destination, that starts after my modem / gateway. The second part of the problem is mostly clerical, ATT seems to be using IANA documentation space inside their network, which DSL support has no explanation for. If someone from ATT could reach out to me off-list, that would be greatly appreciated. db-353-fw01> traceroute 8.8.8.8 traceroute to 8.8.8.8 (8.8.8.8), 30 hops max, 40 byte packets 1 75.39.205.94 (75.39.205.94) 2.451 ms 2.713 ms 2.693 ms 2 192.0.2.100 (192.0.2.100) 882.693 ms 1375.347 ms 682.396 ms 3 12.83.37.201 (12.83.37.201) 993.819 ms 1436.967 ms 616.373 ms 4 12.122.85.197 (12.122.85.197) 944.982 ms 911.500 ms 676.696 ms 5 206.121.120.70 (206.121.120.70) 937.521 ms 1312.248 ms 206.121.120.66 (206.121.120.66) 1353.350 ms 6 216.239.40.139 (216.239.40.139) 1756.335 ms 216.239.54.109 (216.239.54.109) 1117.386 ms * 7 72.14.238.45 (72.14.238.45) 1710.237 ms 64.233.175.9 (64.233.175.9) 1005.727 ms 64.233.174.151 (64.233.174.151) 1707.119 ms 8 google-public-dns-a.google.com (8.8.8.8) 1468.629 ms 1529.764 ms 834.876 ms admin@db-353-fw01> traceroute 4.2.2.2 traceroute to 4.2.2.2 (4.2.2.2), 30 hops max, 40 byte packets 1 75.39.205.94 (75.39.205.94) 2.702 ms 5.745 ms 6.493 ms 2 192.0.2.100 (192.0.2.100) 1986.510 ms 621.122 ms 604.383 ms 3 12.83.37.201 (12.83.37.201) 1202.705 ms 1886.382 ms 1821.073 ms 4 gar26.dlstx.ip.att.net (12.123.16.109) 1458.154 ms 1338.124 ms 1766.894 ms 5 * * * 6 ae-3-80.edge2.Dallas1.Level3.net (4.69.145.139) 999.252 ms ae-1-60.edge2.Dallas1.Level3.net (4.69.145.11) 1597.016 ms 1843.397 ms 7 ae-4-90.edge2.Dallas1.Level3.net (4.69.145.203) 2156.637 ms ae-1-60.edge2.Dallas1.Level3.net (4.69.145.11) 1125.729 ms ae-4-90.edge2.Dallas1.Level3.net (4.69.145.203) 1912.391 ms 8 b.resolvers.Level3.net (4.2.2.2) 1282.430 ms 1640.264 ms 1037.577 ms admin@db-353-fw01> traceroute 12.123.16.109 traceroute to 12.123.16.109 (12.123.16.109), 30 hops max, 40 byte packets 1 75.39.205.94 (75.39.205.94) 2.994 ms 3.034 ms 2.660 ms 2 192.0.2.100 (192.0.2.100) 626.326 ms 1637.689 ms 1883.235 ms 3 12.83.37.205 (12.83.37.205) 1972.528 ms !X * * /Charles

10gig pricing with Verizon crazy?
by David Hubbard 17 Mar '16

17 Mar '16

Curious if anyone has had similar experience; looking for a 10gig transit circuit at a colo, contacted VZ as they’re on net in the facility, quoted me an astronomical amount at 10-20x going rates these days. I’m curious if I just happened across a bad rep and should dig further, or that’s par for the course? Rep was comfortable talking about BGP, v4/v6, etc. so I felt like I was talking to the right person until I saw the price lol. Thanks, David

Two of these prefixes I see via direct peering with Google and, alternatively, via Cogent through Zayo transit.

remote serial console (IP to Serial)
by greg whynott 16 Mar '16

16 Mar '16

Recently I have taking over the responsibility of managing about 18 remote routers and firewalls. None of these have a console port for 'out of band' access accessible today. Most sites has available IPs between the ISP and us (typically a /29) or a backup DSL connection available for use. I'd like to purchase a IP to Serial port device I can use for each location in the event I lock myself out. The requirement would be an Ethernet port, a serial port, and SSH. Anyone have any recommendations on something like this? thanks much, greg

Looking to see what others are using out there as an alternative to a Cisco ME3600X? Also, what other vendors out there are playing in this space? Need a full MPLS stack.

Juniper MX Sizing
by Graham Johnston 15 Mar '16

15 Mar '16

I am wondering if anyone can provide their real world experience about sizing Juniper MX routers as it relates to BGP. I am needing a device that has a mix of layer 2 and 3 features, including MPLS, that will have a very low port count requirement that will primarily be used at a remote POP site to connect to the local IX as well as one or two full route transit providers. The MX104 has what I need from a physical standpoint and a data plane standpoint, as well as power consumption figures. My only concern is whether the REs have enough horsepower to churn through the convergence calculations at a rate that operators in this situation would find acceptable. I realize that 'acceptable' is a moving target so I would happily accept feedback from people using them as to how long it takes and their happiness with the product. For those of you that deem the MX104 unacceptable in this kind of role and moved up to the MX240, what RE did you elect to use? Thanks, Graham Johnston Network Planner Westman Communications Group 204.717.2829 johnstong(a)westmancom.com<mailto:johnstong@westmancom.com> P think green; don't print this email.
