Route Flap Damping
by Rob Evans 04 Jan '13

04 Jan '13

Hi all, Whilst it may not have exactly set the mailing list alight, there were a few voices in support of publishing this document and none against it, so I will ask the NCC to make the working group's recommendations on route flap damping a RIPE document. Please start thinking about what you want to see discussed at our meeting in Dublin in a few months time! All the best, Rob
