[routing-wg]Working group session at RIPE 58.
by Rob Evans 17 Mar '09

17 Mar '09

Hi all, RIPE 58, back in the familiar haunt of the Krasnapolsky in Amsterdam, is approaching fast. The routing working group is scheduled in its regular slot after Thursday's lunch (subject to change!), and the chairs (Joao, Joachim and myself) would like to know what you want to talk about. If there's something you want to present or something you feel the working group should be doing and want to stand up and call for help, drop myself and the other chairs a note. Thanks, and see you in Amsterdam, Rob, Joao, Joachim

[routing-wg]peering change on route-views.routeviews.org
by John Kemp 13 Mar '09

13 Mar '09

We are losing the transit to the previous peering address for the route-views router: 198.32.162.100 Your peering to us there is/was: neighbor 193.0.0.56 remote-as 3333 neighbor 193.0.0.56 peer-group multicast-ebgp neighbor 193.0.0.56 description RIPE NCC If you could change that to peer with: 128.223.51.103 that session should come up now. It is actually the same router, but a different interface. Sorry about the short notice on this. If there is a different channel I should contact about this, please let me know. NOTE: route-views.routeviews.org is an operational looking glass. No data is currently being archived from this device, but the telnet cli remains for operational use. -- John Kemp RouteViews Engineer kemp(a)network-services.uoregon.edu 541-346-1714
