[Apologies for duplicate e-mails] Dear Colleagues, On Thursday, 26 October 2006, there will be planned maintenance on the Routing Information Service (RIS). This work will allow us to avoid several issues related to disabling keepalives for BGP sessions. Between 13:00 and 16:00 (UTC), we will install a new version (0.98.6) of the BGP routing software (Quagga) on our remote route collector (RRC) connected to the Vienna Internet Exchange (VIX). During the maintenance, no routing data will be collected on this RRC and the looking glass for this RRC may not be available. Other services, including the looking glass and data collection for the other RRCs, will not be affected. This upgrade will include a patch we have written to skip the BGP keepalives when dumping the raw data files. Previously, we disabled keepalives everywhere we could, to prevent polluting the raw data files. However, this can cause difficult issues with peerings. If the upgrade causes no problems, we will set all our peerings to use keepalives a few days after the upgrade. If this works well, we will perform the same procedure on all our RRCs. Changing the keepalive settings will not affect the service. We thank you for your patience and apologise for any inconvenience this maintenance may cause.. If you have any questions about this work, please e-mail us at: ris@ripe.net Regards, Erik Romijn RIS Operations RIPE NCC
