Default routes on BGP routers with full feeds
by Berry Mobley 04 Nov '14

04 Nov '14

I'm wondering how many of you who are multihomed also add default routes pointing to your providers from whom you are receiving full feeds. If so, why? If not, why not? Thanks, Berry

BGP Security Research Question
by Anthony Weems 04 Nov '14

04 Nov '14

I'm a student in college learning about networking and, specifically, BGP. Does anyone have any statistics on the use of S-BGP or soBGP in the wild? I've read a few papers / RFCs on the subject (from Cisco and the like), but I haven't been able to find any information about actual usage. Additionally, do people scan BGP speakers in the same sense that researchers perform scans of the Internet (e.g. zmap)? -- Anthony Weems

Learning about the internet

Hi, I was just reading about transatlantic cabling in some hopes that I would be able to find an answer as to why the latency between here in greece and Los Angeles is roughly ~250ms. This seems to be a really common thing, although I'd like to understand why and the articles on transatlantic cabling as near as I can tell indicate that I am getting screwed if anything (not enough information?) (from Los Angeles to my house) Konsole output Konsole output gw~ #mtr --report-wide xxxxxxxxxxxxxxx.access.hol.gr Start: Mon Nov 3 13:04:02 2014 HOST: gw Loss% Snt Last Avg Best Wrst StDev 1.|-- 208.79.92.65 10.0% 10 1.5 3.6 1.2 15.5 4.6 2.|-- s7.lax.arpnetworks.com 0.0% 10 0.8 10.9 0.8 54.2 20.7 3.|-- vlan953.car2.LosAngeles1.Level3.net 30.0% 10 10.5 10.3 10.1 10.8 0.0 4.|-- ae-27-27.edge6.LosAngeles1.Level3.net 30.0% 10 21.8 16.2 8.6 47.6 14.7 5.|-- ae-4-90.edge1.LosAngeles6.Level3.net 80.0% 10 9.0 8.9 8.7 9.0 0.0 6.|-- be3036.ccr21.lax04.atlas.cogentco.com 10.0% 10 1.7 2.1 1.4 4.3 0.7 7.|-- be2076.mpd22.lax01.atlas.cogentco.com 10.0% 10 1.6 1.9 1.6 3.2 0.0 8.|-- be2068.ccr22.iah01.atlas.cogentco.com 0.0% 10 37.7 37.7 37.3 39.0 0.3 9.|-- be2173.ccr42.atl01.atlas.cogentco.com 0.0% 10 51.6 52.4 51.5 57.5 1.7 10.|-- be2171.mpd22.dca01.atlas.cogentco.com 0.0% 10 62.6 62.7 62.4 63.3 0.0 11.|-- be2112.ccr41.iad02.atlas.cogentco.com 0.0% 10 155.5 155.8 155.5 156.1 0.0 12.|-- be2268.ccr42.par01.atlas.cogentco.com 0.0% 10 152.6 152.7 152.5 153.5 0.0 13.|-- be2278.ccr42.fra03.atlas.cogentco.com 0.0% 10 155.3 155.4 155.1 155.5 0.0 14.|-- be2229.ccr22.muc01.atlas.cogentco.com 0.0% 10 161.2 161.1 160.9 161.3 0.0 15.|-- be2223.ccr21.vie01.atlas.cogentco.com 0.0% 10 164.9 165.1 164.9 165.2 0.0 16.|-- be2046.ccr21.sof02.atlas.cogentco.com 0.0% 10 189.5 189.4 189.3 189.9 0.0 17.|-- be2118.rcr11.ath01.atlas.cogentco.com 0.0% 10 197.5 197.6 197.4 197.7 0.0 18.|-- 149.11.120.38 0.0% 10 202.7 202.2 200.3 204.2 1.4 19.|-- 62.38.97.113 80.0% 10 208.5 209.8 208.5 211.1 1.7 20.|-- gigaeth04-13.krs00.ar.hol.gr 60.0% 10 211.3 213.0 211.2 218.2 3.4 21.|-- ??? 100.0 10 0.0 0.0 0.0 0.0 0.0 22.|-- xxxxxxxxxxxxxxxx.access.hol.gr 40.0% 10 231.3 231.4 231.2 231.7 0.0 gw~ # And to be more clear: I am hoping to learn about the complex trials that these packets are going through and how time is being lost if the latency across the transatlantic cable is really capable of less the 60ms of latency? Sure over capacity (3.2Tbits/s wow jeez) is one answer, but what are some other possibilities for loss of time? Also it seems with my VPN (OpenVPN) tunnel I get the most reliable connection (fewest drops) with: Konsole output mssfix 576 fragment 576 Although this could be a false positive as it only *seems* to help with reliability since I changed it. Even then but less often than before I still experience drops but I want to believe that's possibly due to my ISP at that point.. but assuming my ISP was absolutely perfect and never a problem what else there to consider? Any and all insight is appreciated. -Paige
