| mnathani | @smokeping | [12:42] |
| BryceBot | https://smokeping.cobryce.com/ | [12:42] |
| brycec | btw the Time Warner connection was out for an hour earlier
(hence the giant gap) | [12:42] |
| mnathani | brycec: you dont measure latency to each kvr host do you? | [12:43] |
| brycec | no
just from kvr07 I don't have IP's for each host I guess I do come to think of it but the value is questionable | [12:44] |
| mnathani | kvr[02-30].arpnetworks.com
externally it would help from your slave nodes | [12:44] |
| brycec | How so? A connection to ARp is a connection to ARP | [12:45] |
| mnathani | could pinpoint DDOS against specific hosts | [12:45] |
| brycec | More like high load on a given host
a ddos would affect all of arp at least all of a given transit | [12:45] |

mnathani: CaZe : there was a spike of traffic to kvr30 last night, yeah | [17:43] |
| ........ (idle for 36mn) | ||
| mercutio | up_the_irons: is level3 inbound planned for this week now?
i noticed that outbound seemed to be going via level3 rather than any2ix right now. | [18:20] |
| up_the_irons | mercutio: there hasn't been a change to outgoing. i could possible plan level3 inbound this week... | [18:25] |
| mercutio | up_the_irons: curious. it was taking that path when any2ix had issues before, but not for long. but smokeping suggests it's been happening a couple of days or such.
oh it's not all any2ix has any2ix traffic dropped in the last couple of days? facebook still seems to go over any2ix | [18:25] |
| brycec | facebook goes over ntt for me (from kvr07) | [18:28] |
| mercutio | curious | [18:28] |
| brycec | Also, ipv6
:P | [18:28] |
| mercutio | www.facebook.com is an alias for star.c10r.facebook.com.
star.c10r.facebook.com has address 69.171.230.5 oh i'm going over ipv4 | [18:29] |
| up_the_irons | wut.. shouldn't be any difference between anyone's routing ;) | [18:29] |
| brycec | up_the_irons: v4 vs v6 | [18:29] |
| up_the_irons | kvrXX all go thru same path
ah mercutio: i don't see a difference in any2 traffic the last couple days. but there does seem to have been a drop from like, a month ago | [18:29] |
| mercutio | curious.
a looking glass would be nice :) | [18:30] |
| up_the_irons | set one up for me | [18:30] |
| brycec | Odd, v4 goes over coresite | [18:30] |
| up_the_irons | ;) | [18:30] |
| brycec | both v6 and v4 http://sprunge.us/OBbL | [18:30] |
| mercutio | up_the_irons: sure. | [18:30] |
| up_the_irons | i'll give you the session peer | [18:30] |
| mercutio | with bgp multihop? | [18:31] |
| up_the_irons | tell me if there is anything special i need to do on my end for the session (Cisco config) | [18:31] |
| brycec | Yay ARP's own LG | [18:31] |
| mercutio | can it mirror somehow
will look into mirroring | [18:31] |
| up_the_irons | let me see... how did i do this for zeit and brycec ... i think i put a VM under my own account and handed it off.. | [18:32] |
| mercutio | i dunno if there's some easy way to do that so can find out what the different providers thing for routes, rather than what you think for route.
but could get some idea just from having peers to all 3 of routers i suppose | [18:32] |
| apparently there's something called add-path
http://www.nanog.org/meetings/nanog48/presentations/Tuesday/Ward_AddPath_N48.pdf no idea if your router would support it though or what looking glass would do with it http://www.cisco.com/c/en/us/td/docs/ios-xml/ios/iproute_bgp/configuration/xe-3s/irg-xe-3s-book/irg-additional-paths.html#GUID-4EB13F76-7C14-4B74-AFE0-66BF07976BD5 it's pretty cool anyway | [18:38] | |
| brycec | I looked into what it would take to setup an LG for ARP and this was the most solid http://www.ogris.de/howtos/openbsd-looking-glass.html
(in the past, I did this) | [18:40] |
| mercutio | yeh that was my plan bryce. | [18:40] |
| brycec | So that's my $.02 :D | [18:41] |
| mercutio | but bird has bgp add-path support in beta
i wonder if something else supports it | [18:41] |
| brycec | (I'm no expert on BGP so I wouldn't be a very good candidate at adminning it) | [18:41] |
| mercutio | i suppose can look into that later anyway.
basically add-path means if there are routes from level3 and ntt on the same router, they can both be forwarded along, so the route server in theory can show both paths and the as lengths. err the looking glass can show. | [18:41] |
| brycec | ah | [18:42] |
| mercutio | but a simple looking glass would still be way better than none
apparently bird has a beta looking glass and bgp add-path in beta. not sure if the bird looking glass works with add-path though | [18:42] |

| it seems there aren't over 512k routes yet.
http://bgp.potaroo.net/as2.0/bgp-active.html getting close though | [19:05] | |
| up_the_irons | we are getting very close to 512k routes | [19:06] |
| mercutio | yeah, there was that incident a while back when it went over temporarily. | [19:07] |
| up_the_irons | s7.lax>sh ip cef sum
IPv4 CEF is enabled for distributed and running VRF Default 506853 prefixes (506853/0 fwd/non-fwd) Table id 0x0 Database epoch: 3 (506853 entries at this epoch) 506K for me :) yes, we all blame verizon | [19:07] |
| mercutio | i was looking at how much ram openbgpd uses.
and atm looking glass is probably fine on 512mb of ram, but i dunno how long that'd last. taht's with 1.25 million routes. well two full tables plus one partial. i imagine there's some separte ram usage for used routes vs known routes et.c | [19:07] |
