BGP (in)security makes the AP wire
by Mmaad Dooog 11 May '10

11 May '10

Is anyone going to jump on the irony of the last two paragraphs? Having to use the excessively rigid, slow, static, boring expensive PSTN to fix the cool, fast, flexible cheap, cool, fun Internet? That'll work just fine, of course. Until, that is, one of the telcos in the path saves a few bucks and routes a call leg over the Internet. What will us network operators do when there is NO out of band management path to anything? What will happen when you can't even place a phone call? The PSTN ran about 80 years or so on in-band signaling until a very rational cost/benefit decision was made to remove signaling from the traffic path. Physically seperating signaling (SS7) and routing (LERG, etc) paths from the traffic (for all but the access link) was a large, expensive, difficult effort, but worth it. The PSTN is full of quasi-governmental central authorities for everything, and is all the better for it. At some point, the best-effort, cooperative, come-as-you-are paradigm that let the Internet grow fast and far will probably be overtaken by the societal need for reliable, deterministic, assured performance. This thread has discussed only evolutionary, incremental improvements. Who are the revolutionaries among us?

I've worked for a couple of very large providers. I can't speak for what the do they do today but both where very serious about proper filtering. I only hope they both still do it. -jim ------Original Message------ From: Hank Nussbacher To: Thomas Magill Cc: nanog(a)nanog.org Subject: RE: Securing the BGP or controlling it?

> this is a matter of risk analysis. No secure routing means we'll continue > to see the occasional high profile outage which is dealt with very quickly. Speaking from painful experience all kinds of variable can ensure that even when a problem is identified quickly and action taken expeditiously outages can and do take much longer than "very quickly" to correct. Also, while (IMHO) the much higher level of private interconnects / peering links in use today vs. 1997 makes willful route hijacking more difficult, building better security directly into the protocol is certainly in order. A good parallel is the SS7 network that runs "routing" for traditional voice signaling: it's "secured" by using a completely separate, out of band TDM network (DS1s and DS0s) but its also an "in the clear" protocol and could be subject to willful vandalism.

Has anyone here heard of or do they themselves charge extra for providing a complete internet table to customers? Waive the surcharge for sufficiently large commits?

IMPORTANT - Comcast IPv6 Trials
by John Jason Brzozowski 09 May '10

09 May '10

Folks, Wanted to send a short note out about some email that you have seen recently regarding Comcast's IPv6 trials. When you visit http://trial.comcast.net please be sure that you visit the following link "Completed Introduction Survey?" at the bottom right hand side of the IPv6 trial page. This survey is very important, we need the information you supply to properly plan various aspects of our trials. Also, when entering in your information in the "Completed Introduction Survey?" please try to enter only the information requested. For example for your phone number please just enter your phone number and be sure to supply the one that is associated with your Comcast account. Also, when supplying your cable modem MAC address please only enter the MAC address of the cable modem. I also see there has been a fair amount of activity in the forum area of our trial portal. I will try to post some additional information there soon in response to some questions. Thanks again and please let me know if you have any questions. John ========================================= John Jason Brzozowski Comcast Cable e) mailto:john_brzozowski@cable.comcast.com o) 609-377-6594 m) 484-962-0060 w) http://www.comcast6.net =========================================

Books for the NOC guys...
by Robert E. Seastrom 09 May '10

09 May '10

This morning I went digging for a book to recommend that someone in our NOC read in order to understand at a high level how Internet infrastructure works (bgp, igps, etc) and discovered that the old standbys (Huitema, Halabi, Perlman) have all not been updated in a decade or so. On the one hand, they're all still quite relevant since there hasn't been anything really earth-shattering in that department, but they are all going to be lean to nonexistent on stuff like IPv6 and NLRI negotiation. So, what are you having your up-and-coming NOC staff read? Thanks, -r
