------- Dear Colleagues The RIPE NCC Training Services Department invites you to register for one of our upcoming Routing Registry Training Courses: Date: Friday 13 January 2006 Time: 0900 - 1700 Location: Stuttgart, Germany Hosted by T-com: http://www.t-com.de/ And Date: Tuesday 14 February 2006 Time: 0900 - 1700 Location: Manama, Bahrain Hosted by 2connect: http://www.2connectbahrain.com/ And Date: Friday 10 March 2006 Time: 0900 - 1700 Location: Kiev, Ukraine The main objective of the "Routing Registry Training Course" is to familiarise the LIRs with the features of the Routing Registry, while introducing the relevant tools and services of the RIPE NCC. The course also offers practical exercises. OVERVIEW OF TOPICS COVERED IN THE COURSE: - Routing Registry as a part of the RIPE Whois Database and the Internet Routing Registry (IRR) - Specifying routing policies using (RPSL) Routing Policy Specification Language and the RtConfig tool - IRRToolSet - Routing Information Service (RIS) - Routing Registry Consistency Check Project Please note that this is an advanced course. It will: - NOT teach the basics of routing - NOT teach the basics of RIPE Database operations - NOT describe how to receive Internet resources from the RIPE NCC - NOT describe how to operate a Local Internet Registry (LIR) The target audience of the course are technical staff of LIRs: e.g. network operators, engineers etc. This course is not intended for administrative or management staff (e.g. Hostmasters) . It is assumed that all attendees will be familiar with Border Gateway Protocol routing and with the RIPE Database (i.e. creating/modifying objects). This course is based on interactive exercises in a local network set-up. Please bring your laptops equipped with the following: - A working Ethernet card, - Three meters of Ethernet cable, - A secure connection client, - A web browser. Please be prepared to share your laptop (or at least allow another attendee to "look over your shoulder") if necessary. The course is free of charge. We provide lunch and printed training materials.
