Follow up to previous post regarding SAAVIS
by Drew Weaver 14 Aug '09

Anyone know why SAAVIS would be allowing PEER1 (AS 13768) to advertise routes for whatever IP addresses they want? route-views.oregon-ix.net>sh ip bgp 173.45.110.0 | i 13768 2905 701 3561 13768 1221 4637 3561 13768 3549 3561 13768 3277 3267 174 3561 13768 6539 3561 13768 16150 3549 3561 13768 701 3561 13768 3267 174 3561 13768 6453 3561 13768 3582 3701 3356 3561 13768 This is probably a fairly major problem... -Drew

Any Qwest routing engineers?
by Jon Lewis 14 Aug '09

14 Aug '09

I hate doing this, but I'd appreciate it if someone who can look at routing issues inside AS209 would contact me. We're not a customer, but one of our customers noticed they (actually, our whole network) couldn't reach one of your multihomed customers. Traces stop at chi-edge-25.inet.qwest.net. Rerouting the traffic to avoid AS209 "solved" the problem...but perhaps we can get the real problem found & fixed? ---------------------------------------------------------------------- Jon Lewis | I route Senior Network Engineer | therefore you are Atlantic Net | _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________

IPv6 Interview: XS4ALL rolls out native v6 to DSL customers
by Alex Band 14 Aug '09

14 Aug '09

http://www.youtube.com/watch?v=f3WcWBIQ11A Marco Hogewoning of Dutch ISP XS4ALL talks about the roll out of IPv6 in their 300,000 customer network. German modem vendor AVM supplies them with a CPE that supports native IPv6, although it does have some limitations that need to be ironed out. Marco talks about how they got in touch with them, how they handle the spec and the issues, and how the project gained traction when the Sales department got interested. Enjoy, -Alex

Residential BW Planning
by sjk 13 Aug '09

13 Aug '09

I am trying to perform some capacity planning for some of our residential pops, but the old calcs I used to use seem useless -- as they were adapted from the dialup days and relied upon a percentage of users online (~50%) and a percentage of concurrent transmission (~19%). My present scenario involves a micro-pop terminating 250 residences where users are expecting 4 mb/s. So I am looking for some baseline to begin at, so I am wondering what others are doing. Any thoughts are appreciated. Thanks --steve

Visualizing BGP paths
by Dylan Ebner 12 Aug '09

12 Aug '09

I have been working on a project to better illustrate for our manages the provider path data takes when it flows from one of our customers to our datacenter. I have tried to use trace routes to illustrate the number of hops data takes, but when I try to show many sources on one page, it gets fairly messy quickly. I am also less concerned with the number of hops, and more concerned with the number of providers. Does anyone know of a toolset that will take a list of source IP's and a destination IP and show graphically which as numbers the packets need to traverse to reach our datacenter? I am thinking of something like this: http://www.robtex.com/as/as19629.html#graph, but instead of all the upstreams it would show something like AS16150 -> AS1239 -> AS209 -> AS19629. Dylan Ebner

I use BGPLay for showing our connected status, but it doesn't let me put in a source IP/AS and a destination IP/AS. BGPlay is very helpful though.

Re: IM based BGP route-server interface
by mkarir 12 Aug '09

12 Aug '09

All, Thanks to all who responded and provided useful feedback. We had an overwhelmingly positive response. We have incorporated a bunch of comments into the new version of the bot that is currently live. Some of the most visible changes are: - added minimal support for ping and traceroute from the bot interface - added a new aslookup command to provide a quick conversion of AS numbers to names and names to as numbers - added a show ip bgp view command to list possible views that can be queried - added support for cisco shortcuts - IPv6 bgp views should be available soon as well. - the jabber version of the bot was moved to a new server. The new versions of the bots are currently live at: AIM: bgpbotz Jabber: bgpbotz(a)jabber.research.merit.edu We would be happy to add more BGP views to the bot if anyone is willing to provide us with a BGP feed. So far we have only received 1 BGP feed offer. The new version of the bot code has been updated on the website as well if folks want to give that a shot. http://software.merit.edu/bgpbotz Comments and feedback are welcome and appreciated. Thanks.
