Will a single /27 get fully routed these days?
by Drew Linsalata 27 Jan '14

27 Jan '14

Yeah, its been a while since I had to get involved in this. We have a customer with their own IPv4 allocation that wants us to announce a /27 for them. Back in "the day", it was /24 or larger or all bets were off. Is that still the case now?

China ISPs DNS problems on Jan 22nd - any idea what happened?
by Patrick van Staveren 27 Jan '14

27 Jan '14

This past Tuesday the 22nd I was witness to a widespread DNS poisoning problem in China, whereby a lot of DNS queries were all returning the same IP address, 65.49.2.178. Our websites became unavailable for most of our customers in China, as with many other websites. The major difficulty that we had with one of our websites is that we use Akamai's CDN, and Akamai's servers within China were unable to reach our origin server in London - so it originally appeared as if Akamai was having an issue before unofficial news surfaced that there was a larger problem going on. I have two questions for anyone: 1) I've found quite a bit of unofficial news [1] [2] on what happened, but does anyone know what *actually* happened? The only official news from the government that I can find says, "It was probably a cyberattack, but really, we don't know." [3] 2) As a website & network operator who strives to keep their product always available, is there anything I can actually do to prevent from this in the future? The most fun question I think everyone would love to know is - does anyone from Hurricane Electric have a throughput graph showing the traffic surge caused by this? It must be epic.

L2TPv3/MPLS (TP) Pseudowire to preserve
by Herro91 26 Jan '14

26 Jan '14

Hi, We have a new requirement to load balance across a couple of point to point ethernet links. The previous solution was handled by a few TDM circuits and MLPPP so that traffic was load balanced and any fragmentation/reassembly was handled by ML/PPP. Load balancing per flow is not really an option because we have a single IPSec tunnel (ESP-mode) and there is Layer 4 information to make a better decision to balance the load. I have been considering the use of L2TPv3 or an MPLS Pseudowire as a potential solution as they seem to have mechanisms to ensure packets are not misordered. I would appreciate any feedback/suggestions that the community can offer. Best, -Doug

Charter routing issues
by Cody Rose 25 Jan '14

25 Jan '14

Hello, Can someone from Charter Communications enlighten us to if you are having any issues or reach out to me directly. We are seeing some interesting traceroutes from St. Louis, Mo to St. Louis Charter customers via Level3, Qwest, or Cogent. Packets are being sent all over resulting in traceroutes 20 hops long. We are also seeing high latency between Qwest to XO for some routes. 1184.175.64.225 (184.175.64.225) 0.267 ms 0.241 ms 0.419 ms 2 172.23.27.2 (172.23.27.2) 30.195 ms 30.184 ms 30.176 ms 3 te-8-3.car1.StLouis1.Level3.net (4.53.161.53) 0.784 ms 0.782 ms 0.923 ms 4 ae-6-6.ebr2.Denver1.Level3.net (4.69.132.182) 33.222 ms 33.314 ms 33.295 ms 5 ae-1-100.ebr1.Denver1.Level3.net (4.69.151.181) 33.401 ms 33.358 ms 33.361 ms 6 ae-2-2.ebr2.Dallas1.Level3.net (4.69.132.106) 33.181 ms 32.876 ms 32.874 ms 7 ae-82-82.csw3.Dallas1.Level3.net (4.69.151.153) 32.871 ms ae-92-92.csw4.Dallas1.Level3.net (4.69.151.165) 33.111 ms ae-72-72.csw2.Dallas1.Level3.net (4.69.151.141) 33.600 ms 8 ae-2-70.edge2.Dallas1.Level3.net (4.69.145.75) 33.047 ms ae-1-60.edge2.Dallas1.Level3.net (4.69.145.11) 32.879 ms 33.072 ms 9 CHARTER-COM.edge2.Dallas1.Level3.net (4.71.220.254) 34.095 ms CHARTER-COM.edge2.Dallas1.Level3.net (4.71.221.34) 32.178 ms CHARTER-COM.edge2.Dallas1.Level3.net (4.71.221.58) 35.925 ms 10 dtr01ovldmo-bue-4.ovld.mo.charter.com (96.34.2.19) 30.266 ms 30.263 ms 30.546 ms 11 crr01ovldmo-bue-100.ovld.mo.charter.com (96.34.49.220) 30.347 ms 30.563 ms 30.151 ms 12 crr02rxnail-tge-0-7-0-17.rxna.il.charter.com (96.34.50.115) 31.103 ms crr02rxnail-tge-0-7-0-19.rxna.il.charter.com (96.34.50.119) 31.106 ms crr02rxnail-tge-0-7-0-17.rxna.il.charter.com (96.34.50.115) 31.153 ms 13 crr01rxnail-tge-0-6-1-1.rxna.il.charter.com (96.34.50.16) 31.151 ms crr01rxnail-tge-0-6-1-2.rxna.il.charter.com (96.34.50.18) 31.219 ms crr01rxnail-tge-0-6-1-3.rxna.il.charter.com (96.34.49.190) 32.047 ms 14 crr02blvlil-bue-2.blvl.il.charter.com (96.34.50.97) 32.156 ms 32.249 ms 32.247 ms 15 dtr02blvlil-bue-100.blvl.il.charter.com (96.34.50.149) 31.599 ms crr01blvlil-bue-1.blvl.il.charter.com (96.34.49.232) 31.828 ms 31.552 ms 16 dtr01blvlil-bue-3.blvl.il.charter.com (96.34.49.139) 31.719 ms 32.340 ms 32.284 ms 17 dtr01osbhmo-tge-0-7-1-3.osbh.mo.charter.com (96.34.48.124) 36.638 ms 36.646 ms 36.640 ms 18 acr01osbhmo-tge-3-2.osbh.mo.charter.com (96.34.50.35) 36.762 ms 36.850 ms * 19 cts01osbhmo-tge-1-0-0.osbh.mo.charter.com (96.34.56.15) 36.001 ms 36.926 ms 36.926 ms 20 10.174.65.96 (10.174.65.96) 48.686 ms 48.686 ms 48.659 ms 21 24-240-188-2.static.stls.mo.charter.com (24.240.188.2) 44.111 ms 48.208 ms 53.722 ms # traceroute 75.128.167.38 traceroute to 75.128.167.38 (75.128.167.38), 30 hops max, 60 byte packets 1 bowser.video-direct.net (184.175.64.225) 0.246 ms 0.266 ms 0.262 ms 2 172.23.27.2 (172.23.27.2) 1.555 ms 1.593 ms 1.594 ms 3 crt1-crt2.cybercon.com (216.15.195.182) 1.402 ms 1.472 ms 1.471 ms 4 kcm-edge-17.inet.qwest.net (65.116.48.245) 13.336 ms 13.410 ms 13.405 ms 5 dap-brdr-04.inet.qwest.net (67.14.2.170) 19.025 ms 19.025 ms 18.969 ms 6 * 63.146.26.170 (63.146.26.170) 113.851 ms 113.746 ms 7 207.88.14.238.ptr.us.xo.net (207.88.14.238) 128.318 ms 128.282 ms 128.294 ms 8 ae0d0.mcr1.marylandheights-mo.us.xo.net (216.156.0.178) 126.072 ms 125.980 ms 126.079 ms 9 206.181.23.182 (206.181.23.182) 126.051 ms 126.140 ms 126.108 ms 10 dtr01blvlil-bue-1.blvl.il.charter.com (96.34.2.21) 126.034 ms 125.998 ms * 11 dtr01osbhmo-tge-0-7-1-3.osbh.mo.charter.com (96.34.48.124) 126.074 ms * * 12 acr01osbhmo-tge-3-2.osbh.mo.charter.com (96.34.50.35) 125.978 ms * 122.677 ms 13 cts01osbhmo-tge-1-0-0.osbh.mo.charter.com (96.34.56.15) 122.372 ms 121.404 ms 121.776 ms 14 10.174.64.247 (10.174.64.247) 136.737 ms 136.770 ms 131.410 ms 15 75-128-167-38.static.stls.mo.charter.com (75.128.167.38) 136.380 ms 131.092 ms 134.433 ms Inbound traffic routes seem normal but latency is high. 1 1 ms <1 ms <1 ms 10.0.0.1 2 9 ms 9 ms 9 ms 10.160.192.1 3 10 ms 9 ms 9 ms dtr01ovldmo-tge-0-3-0-13.ovld.mo.charter.com [96.34.52.8] 4 16 ms 17 ms 19 ms bbr01olvemo-bue-4.olve.mo.charter.com [96.34.2.18] 5 117 ms 122 ms 119 ms 63-156-122-145.dia.static.qwest.net [63.156.122.145] 6 120 ms 121 ms 121 ms kcm-edge-17.inet.qwest.net [67.14.11.174] 7 126 ms * 123 ms qwest-gige.cybercon.com [65.116.48.246] 8 40 ms 44 ms 41 ms 216.15.195.205 9 123 ms 124 ms 129 ms65.175.114.250 [65.175.114.250] cody@crt1-re1> show route aspath-regex "^174 20115" active-path match-prefix */24 | match BGP | count Count: 128 lines {master} cody@crt1-re1> show route aspath-regex "^209 20115" active-path match-prefix */24 | match BGP | count Count: 15 lines {master} cody@crt1-re1> show route aspath-regex "^3356 20115" active-path match-prefix */24 | match BGP | count Count: 77 lines cody@crt1-re1> show route aspath-regex "^209 20115" active-path | match BGP | count Count: 161 lines {master} cody@crt1-re1> show route aspath-regex "^174 20115" active-path | match BGP | count Count: 578 lines {master} cody@crt1-re1> show route aspath-regex "^3356 20115" active-path | match BGP | count Count: 396 lines
