Full Abstract

This tutorial covers common problems ISPs have when deploying BGP within their network. It looks at problems with peer establishment, missing routes, inconsistent route selection, and convergence issues. It also looks at real world examples of common errors which are made when deploying BGP, both as iBGP and eBGP, in service provider networks.

Full Abstract

First-generation commercial Internet network engineers used key principles in the way they built, deployed, and operated their networks. The principles were derived and deployed from core theorems that proved to scale during times of exponential growth. Until the publication of RFC 3439, "Some Internet Architectural Guidelines and Philosophy," these principles were undocumented and rarely passed to the next generation of network engineers. This primer discusses in detail the core principles highlighted in RFC 3439 and reviews some of the assumed fundamentals of functional, hierarchical, and modular design that are core tools for today's network designs. http://www.1-4-5.net/~dmm/talks/NANOG33/designing/">http://www.1-4-5.net/~dmm/talks/NANOG33/designing/

Full Abstract

Fault management and diagnosis is a challenge in MPLS networks due to the separation of the control plane and data plane. Several tools are available in Cisco IOS to detect control and data plane failures. This toolset has been expanded to include data plane liveliness check for LDP, TE tunnels and pseudo wires LSPs. This presentation discusses IOS-embedded tools that help troubleshoot the control and data plane in MPLS networks. We review capabilities such as VRF-aware ping and traceroute, in addition to LSP ping, LSP trace, and VCCV for fault management and diagnosis of network elements.

Full Abstract

The applicability of IP fast-reroute as applied to a particular core network is analyzed. This analysis considers loop-free alternates and U-turn alternates. The analysis examines both the effectiveness of the techniques on the various network topologies and the capacity planning implications of using IP fast-reroute.

ISP Security professionals encounter unique security incidents. Miscreants, extortion, attacks on their infrastructure, law enforcement knocking on their doors, rampant worms, botnets gone wild, and collateral damage that knocks out multiple gig links are all types of incidents that an enterprise security professional will never experience. "A Day in the Security Life of an SP" is a new regular session given by service provider security professionals to help the broader NANOG operations community learn about their colleagues' work, point out worries and concern in the industry, and recommend actions that the community can take that would make life easer. For this NANOG we have Don Smith, Security Operations at Qwest.

Speakers
Don Smith, Qwest
Donald Smith is a Security Engineer at Qwest and an Internet Storm Center handler (isc.sans.org). He began his computer career 28 years ago in the Army, on a "portable" analog computer. He worked for CDC and received his first security certification in 1995 (CISSR). He has contributed to various computer security groups, tools, and standards, including TIS-fw toolkit, AISSIM, NISPOM ch8, RFC3871, "Operational Security Requirements for Large ISP IP Network Infrastructure," and SANS NT security and incident handling guides.

Bogons are network prefixes that should never appear in the Internet routing table. These networks are commonly used by miscreants for spam and DDoS attacks, and therefore filtering bogons at your perimeter is generally considered useful. However, these filters must be maintained as the list of unallocated subnets (bogons) changes from time to time. Team Cymru offers a variety of resources to help you maintain your filters, including the Bogon Route Server Project, which can automatically filter bogons on your routers via an eBGP peering session with us. This presentation will give you an overview of options available for automated filtering of bogons within your network.

Dave Deitrich, Team Cymru
Dave Deitrich is a full-time member of Team Cymru and an employee of Cisco Systems. Prior to this he worked for Motorola, IBM, and Computer Sciences Corporation as a network architect, engineer, and troubleshooter.

We report on our experiences in adopting a hardware packet capture solution to improve the ability to capture (and discard) packets on both our existing IDS platform and new IDS solutions to protect our lively environment. The University of California at Santa Cruz School of Engineering is growing and traffic rates are overwhelming the existing IDS PC-based system. Gigabit ports are cropping up all over the department, and major traffic flows go to and from I2. We'll discuss our investigation into next-generation capture cards and our desire to continue to use Snort (www.snort.org) aligned with the discovery and use of some new, interesting technology.

Speakers
Paul Tatarsky, UCSC
Paul Tatarsky is a UNIX sysadmin and security consultant in the Midwest who has spent most of his 15 working years monitoring IDS systems at UCSC on the west coast. He also runs several compute clusters for the Human Genome Project at UCSC and tries to come up with better ways to protect his systems from attack and improve the way he monitors for such attacks.
