RIPE 42

The European Operators Forum (EOF) is a forum where new technology developments of interest to IP network operators are presented and discussed. The EOF has no formal charter or chair. The agenda is coordinated by a programme committee led by Rob Blokzijl, RIPE Chair.

Participation is open to all interested parties. The EOF is normally a day and a half session that takes place prior to scheduled Working Group meetings. The Programme Committee welcomes input for possible topics and can be reached at eof-coord@ripe.net.

RIPE 42 EOF Draft agenda
Chair: Peter Lothberg

10:00 - 15:30 : Advanced BGP Topics Tutorial
Speaker: Daniel Walton (Cisco)

Abstract:

Advanced BGP Topics Tutorial - The tutorial will not cover the details of how BGP works but will focus on more advanced topics such as troubleshooting and convergence. Examples will be given of how to troubleshoot common BGP problems that operators may see every day.
Convergence will be discussed in terms of common bottlenecks for BGP convergence/scalability and how to fix them.

Intended Audience: Network engineers and operators with working knowledge of BGP and experience deploying/troubleshooting/maintaining the protocol.

Table of Contents:

1. Troubleshooting

• peer establishment
• missing routes
• inconsistent route selection
• route oscillation and routing loops

2. Convergence/Scalability

• peer-groups
• TCP path mtu discovery
• Input queue drops
• UPDATE packing
• UPDATE replication

16:00 - 17:30: Pseudowires and L2TPv3
Speakers: Mark Townsley (Cisco) & Gilles Deworm (KPNQWEST)

Abstract:

Emulation of various layer 2 link types ("pseudo-wires") over IP presents an interesting and potentially valuable choice for Internet service providers looking to consolidate disparate networks or provide new services over a common infrastructure.

The Layer Two Tunneling Protocol (L2TP) defined by the IETF provides a necessary basis for tunneling capabilities used in "pseudo -wire" emulation over IP. First used for emulation of PPP data links over IP, L2TP is being adopted for a number of new data link services, including Frame Relay, ATM, Ethernet, and others.

This discussion will provide a technical overview of L2TPv3, as well as a peek into how it is currently being utilised for pseudo-wire services. A brief overview of the PWE3 (pseudo-wire edge to edge) activity in the IETF will also be presented.
