RIPE 49 is getting closer and in order to complete the agenda for the routing wg at the RIPE 49 meeting, taking place in Manchester, UK, 20-24 September, the chairs of the working group would like to request and invite presentation from members of the community on routing topics. Topics can range from operational experience at your networks that you would like to share, talks on routing protocol development and even specific vendor features that may be of interest to networks operators (particularly those not being marketing pitches). If you are interested in presenting or want to find out more about presenting at RIPE 49, contact either me or Joachim Schmitz, the 2 wg co-chairs. See you at RIPE 49 Joao Damas

Virus Warning from the RIPE NCC
by Gerard Leurs 10 Aug '04

10 Aug '04

Dear Colleagues. We are sorry for duplicate emails. On Monday 9 August 2004, a virus (bagle) was mailed to several mailing lists operated by the RIPE NCC. Unfortunately, the virus passed through the filters of several of these lists. At the moment of writing we know this happened for the db-wg, eof-wg, routing-wg. And the wg-chairs. Please do not open any suspicious .zip files. Please make sure you delete any such mails. The RIPE NCC is working to resolve the issue. We apologise for any inconvenience this may have caused. Regards, Gerard Leurs, Operations department, RIPE NCC.
