by RIPE NCC Training 17 Feb '03

17 Feb '03

Dear Colleagues, [apologies for duplicate postings] As a new service to its members the RIPE NCC offers the "Routing Registry Training Course". 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 describe how to receive Internet resources from the RIPE NCC not describe 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 Routing Registry Training Course is conducted in the English language and is free of charge, since it is covered by the membership fee. More information about the Routing Registry Training Course can be found at: http://www.ripe.net/training/rr/ REGISTRATION: You can register for a Routing Registry Training Course at the following URL: http://www.ripe.net/cgi-bin/trainingform.pl.cgi Or by completing the registration form at the end of this e-mail and replying to <training(a)ripe.net> . In order to register for a Routing Registry Training Course you must be an employee of an LIR and either: - be an LIR contact - be confirmed by an LIR contact LIR contacts are those employees of an LIR who are registered with RIPE NCC as authoritative contact persons. It is expected that most of those interested in the Routing Registry Training Course will not be an authoritative contact person for their LIR, and therefore will be, refused by the course registration "robot". In order to be admitted to the course, a confirmation e-mail must be sent to <training(a)ripe.net>. Please approach the LIR contacts from your organisation personally, since the identity of LIR contacts is confidential, and the RIPE NCC is unable to divulge contact persons for any given LIR.
